Your job is to design the collections, indexes, and rules so that: • bookings update in real time for all parties involved •...

I’m rebuilding my site and need an extra pair of hands on both the look-and-feel and the engine that drives it. You should be equally at home crafting a polished, responsive interface in React, Vue, or Angular and wiring it up to a solid back-end running on Node.js, Django, or Rails. Here’s how I picture the collaboration: you’ll jump into my existing code-base (Git repo access provided), refine or replace the current front-end components, build or optimise the API layer, and make sure everything works seamlessly together. Clear commit messages, well-structured pull requests, and clean, documented code are must-haves. To be considered, send me a detailed project proposal outlining: • the stack you recommend for front end and back end, • the milestones ...

​Project Overview ​We run a multi-site platform built with Node.js, React, and MongoDB (Customer site, Partner dashboard, Admin portal). We need a full-stack developer to fix a critical session bug and implement a few business guardrails. ​Immediate Fixes & Features: ​Fix Auto-Logout Bug: Customers log in fine, but attempting to book a service automatically terminates their session and kicks them out.

I need a developer or small team that can own the entire lifecycle of a custom, database-level integration for our business. The work goes far beyond a connector; it involves analysing our existing data flows, designing the architecture, coding the synchronisation logic, and deploying a production-ready solution that supports our bespoke business rules. Because the job is strictly about database integrations, you’ll be working directly with structured data stores. We haven’t locked ourselves into any single engine yet, so part of your brief is to recommend the most appropriate technologies, map the data models, and deliver a maintainable, well-documented codebase that other engineers can extend. Key expectations • Discover and document current data sources and target s...

I need a complete inventory module built with Node.js on the back-end, Angular on the front-end, and MySQL as the data store. The overall project is a business management system, but for this phase I’m focusing solely on inventory management. Here is what has to work from day one: • Stock tracking – real-time quantity updates, low-stock alerts, and simple adjustment logs. • Barcode scanning – generate and read codes directly in the browser; a basic handheld scanner should work out of the box. • Order management – create purchase orders, receive items into stock, and tie outgoing orders to stock deductions. Clean, modular code is important because I’ll be adding CRM and accounting components later. API endpoints should be RESTful, the Angu...

I have a production-ready Node.js application backed by PostgreSQL and now need a complete, automated DevOps workflow on AWS. Everything must live in the cloud, and I specifically want the workload to run on EC2 instances and/or an ECS or EKS cluster—no Lambda in this stack. The assignment covers the full lifecycle: infrastructure provisioning, build and test automation, continuous delivery, monitoring, and rollback strategy. Infrastructure-as-code (Terraform or CloudFormation) is essential so I can reproduce the environment from scratch. A secure, highly available Postgres setup—preferably Amazon RDS with multi-AZ—is required, alongside a VPC, subnets, and the usual security groups. Please containerise the Node service, wire up a CI pipeline (GitHub Actions, GitLab CI,...

I need an experienced mobile engineer to step in, trace, and fix the problems that have crept into my Capacitor-based iOS and Android app. Over the last five months we have suffered four serious data-loading failures. Alongside that, a notification process has gone rogue, hitting MongoDB nonstop and pushing our Google Cloud spend far beyond forecast. We have not spotted any clear usage pattern that triggers the outages, and our own quick analysis of the notification storm still leaves the root cause unknown. Your job is to run a full technical investigation, eliminate the defects, and get both stores running on a clean, optimized build. Deliverables • Root-cause report covering the data-loading incidents and the excessive notification traffic • Remediated code with performanc...

I am rolling out a production-grade workload on AWS and I want the operational foundations built right the first time. The immediate focus is on three areas: 1. CI/CD • Pipeline built around Jenkins, running on AWS. • Automated build, test, and deploy stages for multiple micro-services. • Zero-downtime, blue/green or canary releases where feasible. 2. Infrastructure as Code • Reusable CloudFormation templates (no manual console work) that stand up VPCs, subnets, ECS/EKS clusters (or similar), security groups, and any supporting resources. • Parameterisation and clear documentation so the stack can be reproduced in any account or region. 3. Monitoring & Logging • End-to-end visibility using AWS CloudWatch; integration with l...

I am already more than halfway through building a multi-tenant ERP platform offered as SaaS. The current stack is React on the front-end with a Node.js (Express) API, and subscription payments are flowing through an integrated payment-gateway module. What’s left is to finish the remaining business-logic layers, tighten up the UI, and prepare the whole product for production release. I’ll give you access to the existing Git repository, detailed module road-maps, and the payment gateway keys already in place. Your job is to pick up the codebase, complete the unfinished modules, squash any bugs you find, and push clean, well-commented commits back to the repo. Key expectations: • Keep everything in React + Node.js, following the existing component and controller patte...

I already have an IPO tracking app in production and now need a dedicated backend service that can fetch allotment results from the 30-plus Indian registrars the moment they go live. The entire service must be written in Node.js, since the rest of my stack is JavaScript based. Core expectations • Connect to every major registrar (KFintech, Link Intime, Bigshare, Cameo, Skyline, etc.) and return real-time allotment status using the usual identifiers—PAN, application number, DP/Client ID, or combination thereof. • Normalise the various HTML, CSV, PDF, and basic API outputs into a single clean JSON response. • Build a set of REST endpoints with simple auth, comprehensive error handling, and logs I can pipe into my existing monitoring. • Provide clear deploym...

I’m building a full-featured website for our new pickleball league and need an experienced backend developer to bring the real-time pieces to life. The stack is already chosen: Node.js (Express or NestJS) with PostgreSQL as the primary database. Core tasks • Live player auctions – real-time bidding, instant bid notifications, and a full auction history log powered by Socket.IO. • Live match scoring – endpoints that push each team’s score and stats seconds after every rally so the front-end can update instantly. • Secure auth – JWT sessions plus OTP or token-based magic-link login for captains, admins, and bidders. • Media handling – upload player photos and team assets straight to AWS S3 (or Cloudinary if you prefer) and stor...

I need like Coach Surfing web + mobile app. I have an existing Flutter mobile application that already communicates with a Node.js backend. I now want to push it further: tidy up the current codebase, add several new screens, tighten the API layer on the server, and introduce a small yet meaningful AI feature (think personalised recommendations or basic natural-language queries—exact scope to be agreed together). Here is what I need from you: • Flutter work – polish the present UI, wire in the new screens I will supply as Figma frames, and be sure state management stays clean and predictable. • Node.js work – extend the current Express API, connect the new endpoints to MongoDB, and add role-based authentication so the app can distinguish between guest and...

I’m kicking off a full-stack project and need an experienced developer who can attack both the front-end and back-end at the same time. The stack is already defined: Node.js (my preferred choice even on the front end), React.js with Redux, and a microservice layer in Java Spring Boot. RESTful APIs, PostgreSQL or MySQL on the relational side, and MongoDB for document storage are all part of the architecture. Speed matters—I’m looking to see working code as soon as possible, so we’ll iterate quickly and ship incremental features rather than wait for a big-bang release. Modern JavaScript (ES6+), async/await patterns, and clean module structure are must-haves; so is writing well-tested, production-ready Java Spring Boot microservices. High-level deliverables: • R...

I need access to battle-tested enterprise repositories that exceed 50,000 lines of code. The primary goal is to run AI benchmarking, perform deep architecture reviews, and carry out engineering evaluations for technical due-diligence work. Real-world complexity is essential—simple CRUD samples will be declined. Preferred technology foundations include Java, .NET, Python, Node.js, or React, ideally containerised with Docker or orchestrated through Kubernetes and deployed on AWS, Azure, or GCP. Repos hosted on GitHub, GitLab, Bitbucket, or a private Git server are all welcome. Any supplementary assets—such as PRD/BRD documents, Jira tickets, detailed API docs, architecture diagrams, deployment playbooks, or test artefacts—will significantly strengthen your submission and ...
