I’m looking for help securing one United States VoIP DID that plugs straight into my existing PBX so our support team can start taking customer calls right away. The number must be fully functional for both inbound and outbound traffic and delivered with clear SIP credentials I can drop into my system without extra hardware. You’ll handle everything—from sourcing a reliable carrier, activating the line, and confirming it registers cleanly on my PBX—to ensuring call quality meets normal business-class standards. If you can bundle extras such as voicemail, call recording, or simple forwarding rules, let me know; they aren’t mandatory but would be appreciated. Once the line shows registered and I can place and receive live test calls, the job is done.
My iPhones and several smart-home devices have almost certainly been compromised. Unexplained behaviour, network slow-downs and repeated password lockouts suggest an active intrusion that I have not been able to stop remotely. I need an experienced cyber-security professional to visit in person, trace the breach and leave every device—and the Wi-Fi network itself—clean, secured and fully documented. What I expect during the visit • A thorough forensic check of each affected iPhone and the smart-home hub/gear, including router or mesh nodes you judge relevant. • Immediate containment and removal of any malicious profiles, apps, firmware or network configurations you uncover. • Clear advice on whether each device can be salvaged or should be replaced, follow...
I already have CapRover up and running on my own server, and the root domain is fully configured. What I’m missing is a clean, reliable one-click template that will let me spin up Snipe-IT instantly from the CapRover “One-Click Apps” catalog. Here’s exactly what I need you to deliver: • A `captain-definition` and companion `` entry that pulls the latest stable Snipe-IT Docker image, sets the correct environment variables, maps persistent volumes, and links everything to a fresh MariaDB service (my preferred database for this project). • The MariaDB service itself defined in the same template with sensible defaults and clearly commented placeholders for root password, app user, and database name. • Optional sections for SMTP, HTTPS, and timezon...
I’m looking for a reliable ViciDial pro who can jump in each day and keep my dialer running smoothly. The core of the job is straightforward but must be done consistently: • Run the standard performance and list-based reports I specify, download them, and drop them in our shared folder before end of day. • Import new lead files (CSV) as they arrive, map fields correctly, and verify the list is live. • Check that every active campaign’s leads are sitting in the hopper in the right quantities so agents never run dry. If a hopper is empty—or about to be—top it up and ping me in Slack. Everything is handled remotely; you’ll just need a stable connection, a headset for quick follow-up calls if questions arise, and solid familiarity with the Vic...

**Operating System:** CentOS 7.x (7.9 recommended) **Core Architecture:** Spring Cloud + Kafka + Hadoop + Python Automation **Core Package Name:** ``
We need a full-stack technical staff member with expertise in Java microservice development (Spring Cloud), message queues (Kafka/RabbitMQ), databases and caching (MySQL/Redis), Linux server deployment and maintenance, Nginx gateway configuration, and distributed system debugging to complete the deployment.
I have an existing code-base that needs to be compiled, configured, and deployed on a CentOS 7 server. The stack spans several languages (the repository mixes Java, Python, a bit of C++, and some PHP utility scripts) so I need someone comfortable moving through polyglot projects without breaking stride. (Developed independently using a non-Java language) The immediate goal is a repeatable deployment: building the artefacts, resolving library dependencies, wiring in systemd service files, and validating that everything starts cleanly after a reboot. You’ll work directly on my CentOS 7 instance (SSH access provided) and document any package or kernel-level tweaks you make so I can reproduce the setup on staging and production later. Because the code also ships to a small cross-pla...
I’m rolling out a Python-based platform that keeps an eye on city roads in real time. The first goal is clear: monitor live video from roadside traffic cameras, spot congestion, accidents or blockages within seconds, and push actionable alerts through a cloud-hosted pipeline. Later phases will weave in IoT sensors, GPS data and public-transport schedules, but for now cameras take centre stage and all processing happens in the cloud. Here’s what I need from you: • A complete stream-to-insight workflow: camera feed ingestion → cloud message bus → analytics micro-service. • Computer-vision models (OpenCV, YOLO, TensorFlow—your call) that flag incidents with >90 % precision/recall on my test clips. • A REST API that surfaces live traffic stat...

Our Magento 2 store suddenly refuses to complete the Product Price reindex and shows the familiar “no linked stock” message. Nothing was updated, no extensions were added, and I haven’t tried any quick-fix SQL scripts or CLI commands yet, so you’ll be starting with a clean slate. I’m looking for someone who has already wrestled with this specific indexing glitch and can get the catalog back to a fully reindexed state without disrupting live traffic. Acceptance criteria / deliverables: • Identify the root cause of the “product price index – no linked stock” error and document it briefly. • Apply the corrective fix (database clean-up, configuration adjustment, or code patch) on our staging site, demonstrate a successful bin/magent...

ERPNext v16 is already live on our Linux cloud server—what I need now is the Frappe Drive module (version 15) installed and fully integrated. After the deployment you will map a Synology NAS drive to the server and configure frappe drive so every file, attachment, and upload is stored directly on that NAS share, not on the local disk. Once storage is redirected, I want granular control over space allocation: individual user quotas, department-level shared folders, and clear policies for sharing and syncing with the official Frappe Drive clients on Windows, macOS, Android, and iOS. Every employee should see only the folders they’re permitted to access, while teams (Sales, Finance, Ops, etc.) can collaborate inside their own common spaces. Because this is for an existing busine...

I have between two and ten new workstations that need to be taken from boxed parts to fully-operational machines. Every unit already has its CPU, motherboard, RAM, storage drives, graphics card, and standard peripherals on hand; I just need a reliable technician to install and configure them correctly. Once the hardware is in place I’d like you to load the operating system and the core software applications we use so that each computer boots straight into a ready-to-work environment. Driver updates, basic BIOS tweaks, and any firmware required for stability are expected as part of the job. The installation will take place on-site, and I’ll supply all components, licences, and network credentials. You bring the tools, know-how, and a methodical approach that leaves every machi...
I’m looking for someone who can install and configure OpenClaw on a fresh Linux environment (Ubuntu 24). Once it’s in place I need it tuned specifically for running automation scripts—no other features are required right now. The job is considered finished when: • OpenClaw is installed from source or packages, whatever is most stable on Ubuntu 24. • The automation‐script module is enabled and a sample script executes without errors. • I have a brief README outlining the key commands to start, stop, and update the service. If you’ve compiled similar tools or set up CI-style script runners before, this should be straightforward. open claw open site and login and bet bhave of me what i say to him ho and this mach and bet liek that
I pull live messages (roughly 2 000 users, no media) from one of my own Telegram channels through the raw Telegram API in a Python script, yet every event reaches me several seconds late. That lag ruins the downstream logic I built, so I need another pair of eyes to pinpoint the bottleneck and get as close to true real-time as the API allows. What’s already in place – Python 3.11, Telethon (latest) inside a small async service – Standard getUpdates loop plus a simple database write – No proxy/VPN in between Where I’m stuck Even with a bare-bones handler, the gap between a message appearing in the Telegram client and being processed in my script stays at 4-6 s. I have ruled out network latency and local disk I/O. Your task • Analyse the curren...

I need to move my live React-based website from its current host to a new server and want the transition to be completely seamless for users. The job covers copying the full codebase or production build, recreating environment variables, configuring Node.js and a web server such as Nginx or Apache on the destination machine, migrating SSL, pointing DNS to the new IP, and confirming that every page, route, and API call works exactly as before. Deliverables • Site running flawlessly on the new server, accessible over HTTPS • Step-by-step documentation of the migration and any configuration changes • Quick rollback or recovery plan in case we need to revert I will open a low-traffic window for the switchover so downtime stays near zero. Let me know what access or prelim...
I already have the complete source code for a Python / Django project that is intended to run on a web platform. What’s left is the production-ready deployment. The task is straightforward: set up a reliable hosting environment, configure the required services (virtualenv, database, static and media file handling, SSL, and process manager), then push the code so the site is publicly accessible under my domain. I’m currently undecided on whether to use Apache, Nginx, or another stack; feel free to recommend what you know will keep things stable and easy to maintain. Please make sure that: • The application starts without errors via the chosen server stack. • Migrations, static file collection, and environment variables are handled cleanly. • A short read-m...
I run a small server that relies on a single token embedded in five local bash scripts. That token changes frequently and is published inside a public .m3u file on GitHub. What I need is a lightweight solution that runs every minute from cron, fetches that remote .m3u, pulls out both the URL and its accompanying token, and then slips the fresh values into each of the local scripts where they are currently hard-coded as script parameters. Current state • The five bash files already exist and work; they simply hold outdated, hard-coded parameters. so they probably need to be modified to run like: $token= "" ffmpeg -i "blablabla/$token/channel/ -c copy blabla • The .m3u has a consistent format, so the token and URL can be isolated reliably with a regex or simila...
I want to develop inside IntelliJ IDEA while all compute happens on runpod.io. The goal is a clean Remote Development Environment setup that lets me open the project locally, yet run, debug, and test code on a RunPod container with zero friction. My day-to-day work is mostly Python, and there’s also a Java web-application module I need to keep compiling and serving. I need you to: • Spin up or pick a suitable RunPod image that includes the required Python tooling and a compatible JDK. • Enable secure, persistent SSH access (or JetBrains Gateway) so IntelliJ connects every time without manual tweaks. • Create IntelliJ run/debug configurations for both Python scripts and the Java web app, verifying that breakpoints, unit tests, and console output all work remotely....

I’m ready to rebuild my GoDaddy VPS: it currently runs CentOS and hosts my company websites behind Nginx with SSL enabled. I want the server re-imaged to the latest stable Ubuntu, with every element of the existing stack preserved and an additional n8n instance installed. Scope of work • Perform and store an off-box, full backup of all site files, databases, and current Nginx configurations before any changes begin. • Re-provision the VPS on Ubuntu, harden the OS, and apply basic firewall rules. • Restore my websites, bringing Nginx back online with the original virtual host blocks and SSL certificates so no visitor notices the change. • Install n8n (Docker or native systemd service—whichever fits best on Ubuntu) and expose it securely over HTTPS ge...
I need a small, reliable script that can take batches of raw text files and run them through a fully automated workflow. At a minimum the routine should ingest the files, process the text, and return clean, well-structured output I can feed straight into my existing systems. My current bottleneck is doing this by hand, so the solution must run unattended once configured. Although my immediate goal is straightforward data processing, I’m open to seeing how you’d weave in text extraction, transformation, or even lightweight analysis if that simplifies the pipeline or adds value. I work comfortably with Python, so a solution built with pandas, spaCy, or similar libraries would fit right in, but I’m not married to any single toolset as long as the final deliverable is easy f...
I need reliable freelance computer-hardware engineers who can visit my customers’ offices and homes across India and carry out installation services—specifically Linux installation on their machines for everyday desktop use. Here’s what a typical call looks like: I send you the location and preferred Linux flavour (most often Ubuntu or Mint, though customers occasionally ask for Fedora or Debian). You arrive on site with a bootable USB/DVD, install the OS on a new or existing desktop or laptop, set up common drivers, configure the network, and verify that everything—from Wi-Fi to printers—works smoothly before hand-over. I cover any reimbursable travel expenses that we agree on in advance, and you invoice me once the job is signed off by the customer. So...
During the next 6–9 months we’ll be working with a Chinese OEM that is adding several key capabilities to its new 4G/5G router line: higher data-throughput paths, richer network-management options, and extra data interfaces such as serial ports and general-purpose I/O. All new code must interoperate with the OEM’s own proprietary protocols, so every build needs to be exercised against their closed, in-house stacks. Our immediate need is rigorous quality-assurance and debugging support throughout the development cycle. Your job is to design and run repeatable tests and make sure we meet customer's objective, and feed concise feedback and bug reports to the factory team. Expect iterative rounds of validation on both bench setups and pre-production hardware. Once the ...

I recently moved my custom PHP / MariaDB e-commerce site to a new Ubuntu virtual dedicated server. Since the switch, every page—home, product, checkout, you name it—now loads noticeably slower even though CPU and RAM usage stay low. The job is straightforward: dissect and tune the stack so the site performs at least as quickly as it did on the old box. I’m specifically after smart adjustments to , vhost files, , php-fpm pool settings, and —buffer sizes, innodb settings, query logging, connection limits, the works. Deliverables • Optimised configuration files for Apache, PHP-FPM, and MariaDB, commented so I can see what changed. • A brief report (bullet points are fine) showing baseline vs. post-tuning load times and the reasoning behind each tweak, so...
I am just getting started with Python and would like a patient tutor who can guide me step-by-step, answer my questions as they come up, and help me practise writing clear, working code. The main areas I need to master are: • Basic syntax and data types • Control structures and functions • Libraries and modules Please structure the lessons so each concept is demonstrated with short examples, followed by hands-on exercises I can share back for review. I am happy to work in whichever environment you prefer—IDLE, VS Code, Jupyter Notebook—so long as I can replicate the workflow on my own machine. By the end of our time together I should be comfortable writing small scripts, understanding error messages, and knowing where to look next when I get stuck....
I’m looking for a reliable way to mirror my on-premise SQL database to AWS RDS in real time. The web service you build will capture every change that hits the local tables—customer information, inventory data, and transaction records—then push those changes up to the cloud with minimal latency. My priorities are: • Zero data loss and consistent state between the two stores, even when connectivity drops temporarily. • Latency low enough to feel immediate to downstream apps that rely on the cloud copy. • A straightforward deployment path: I should be able to install the service on a Windows or Linux host beside the local database, point it at the RDS instance, and watch it run. Deliverables 1. Source code for the sync service (language and framewor...

I’m building a live remote-monitoring dashboard that ingests MQTT messages from a teltonikak rtu 901 gateway along with temperature, pressure, and oxygen sensors and many other parameters from a controller. The stack I have in mind runs on DigitalOcean or AWS and is driven by Python on the back-end and JavaScript on the front-end, but I’m happy to discuss refinements if you can justify them. Current status • Devices is yet to publish raw readings over MQTT. • No cloud pipeline, storage layer, or UI exists yet. What I need next • A lightweight yet secure ingestion service (Python is preferred) that subscribes to the topics, validates payloads, and writes them to a scalable store on DigitalOcean. • A real-time dashboard in JavaScript that shows live ...
I’m spinning up a brand-new SA-MP roleplay server and need a complete Pawn script built entirely from scratch. The end result should feel as if it came out of a polished commercial package: clean, modular, thoroughly commented, and fully optimized for desktop and SA-MP mobile clients alike. Core systems I must have • MySQL-driven account and character handling (registration, login, persistent data) • Job framework with at least a fully functional Police-Officer career path (duty toggle, arrest flow, ticketing, rank promotion, on-duty perks) • Faction, gang, and turf logic that can scale without performance drops • Business ownership with Clothing-Store mechanics (inventory, cash flow, stock restock, employee ranks) • Admin suite that, at minimum, s...
I have a brand-new VPS with Hostinger and need it fully configured right away. The server is running Ubuntu, and its sole purpose will be to host websites reliably and securely. I’ll give you root access plus the Hostinger panel credentials; from there, I expect a streamlined, production-ready environment set up without delay. Please bring your own best-practice checklist—speed, stability, and basic hardening are what matter most to me right now. Deliverables • Update Ubuntu to the latest LTS patches • Install and configure a web-server stack (Apache or Nginx—your call, as long as it’s stable) • Enable a firewall, SSH key authentication, and basic fail2ban or equivalent protection • Set up one test virtual host so I can point a domain a...
I maintain a Node.js / TypeScript code-base that submits Jito bundles to the Solana network at high frequency. The current version works, yet under heavy load it saturates network bandwidth, slows slot confirmation, and leaves a larger attack surface than I’m comfortable with. I’d like you to jump in, profile the pipeline, and return an implementation that is measurably better across three axes—performance, scalability, and security. What performance means here is simple: bundles must reach the leader faster so more of them land profitably. I’m especially keen on lowering the chatter between my service and Jito’s relays so network bandwidth is used far more efficiently. You’ll have full access to the existing TypeScript modules, aggregator logic, and t...

I need a reliable automation script that can interact with a browser-based application I use every day. The solution must run smoothly on Windows machines and handle the full workflow without manual clicks or keystrokes. While the main focus is the web interface, I’m open to whichever stack you feel is most stable—Python + Selenium, PowerShell with headless Chrome, or a comparable approach—as long as it can be launched by a non-technical user from a desktop shortcut. What success looks like for me: • The script logs in, completes the required on-screen actions, and exits cleanly. • It reports basic status (success, failure, or any error message) in a simple log file. • Setup is straightforward: a short read-me or a one-time installer that covers any ...

I am rolling out an in-dash Android interactive display and need a seasoned AOSP specialist to turn the stock source into a lean, security-hardened custom ROM. The target hardware is a car-grade unit that hosts a camera alongside proximity and accelerometer sensors, so the build must include the right HALs and permissions for those components. What I want you to handle: • Fork the AOSP branch that best matches our SoC, import or craft the correct device tree and board-config, and fine-tune the kernel where necessary. • Strip every Google Mobile Service while preserving base Android stability. • Apply low-level security tweaks (SELinux policy work, verified boot, hardening flags). • Set up seamless OTA delivery (delta or full images) so field upgrades stay painless. &bu...
I need an experienced telephony engineer to bring up a new IVR on our Asterisk-based server that will answer calls coming in on both a SIP trunk and a PRI.
