Dari 192,552 ulasan, klien menilai .NET Developers kami 4.9 dari 5 bintang.I need a robust Playwright-based automation framework written in C# that follows the opus oe sonet model from Claude and embraces a full BDD workflow. The framework must suit my “Automation framework” target rather than being tied to just one platform, so while web support is the priority, I want the architecture to stay open for possible mobile or desktop extensions. The main focus is on end-to-end automation test coverage, yet the code structure should remain flexible enough that future performance or security layers could drop in without a rewrite. All test logic will live in readable .feature files, with step definitions, hooks, and a central object repository generated automatically. Key deliverables • Framework source in C# (.NET 6 or later) integrating Playwright ...
I need a small-scale Library Management System built with C# and SQL Server that targets just one user group—students. The single workflow I want implemented is book borrowing handled through an online request form. At minimum, students should be able to: • Sign in with a basic account • Search or browse the book catalogue • Submit an Online request to borrow a selected title • View a confirmation that their request has been recorded Behind the scenes the system must store all catalogue data, user accounts and borrow-request records in SQL Server. Clean, parameterised queries or stored procedures are expected so the code is safe and easy to extend later if we decide to add faculty or librarian roles. Deliverables • Complete C# source (desktop WinF...

From Pakistan or India Only new Junior Level Work Needed. I maintain a small-to-medium ASP.NET solution written in C#. Day-to-day work occasionally piles up, so I want to bring in a junior developer who can jump into Visual Studio, pull the latest branch from Git, and tackle clearly defined tasks as they appear. Typical assignments will involve: • Updating or refactoring existing C# classes to keep the codebase clean and readable • Implementing straightforward pages or components in ASP.NET (MVC/Core) under guidance from my side • Writing concise unit tests so we keep coverage intact • Checking in changes via pull request and responding to code-review comments You will always receive a ticket that describes the goal, the current behaviour, the expected result, a...

I already run my business on a desktop-based invoicing tool and can supply its full source code. I want an exact replica built from that code, retaining the entire workflow and interface, but I also need a seamless WhatsApp integration so I can share invoices or payment reminders directly from the app. The new build must run reliably on Windows, match every existing screen and function, and keep all current features—client management, payment tracking, and automated recurring invoices—intact. While you are free to refactor or modernise the codebase for maintainability, the user experience should feel identical to what I have today. Key deliverables: • Compiled Windows installer and signed executable • Complete, well-commented source code • Fully functional ...
I’m expanding a US-based SaaS product team and need an experienced .NET engineer who can own our customer-facing web applications while helping to ship production machine-learning models. Most of our stack lives in C# with ASP.NET MVC and Entity Framework, but our ML pipeline runs in Python, so you should feel at ease moving between both worlds—writing clean controller/API code, optimising queries generated by EF, and wrapping or calling Python models for inference and training. Selected technologies you must already handle: • Entity Framework • Python • AI (machine-learning models) Prior experience at a U.S. company is strongly preferred because we follow U.S. business hours (roughly 9 am–5 pm EST, Monday–Friday). If you enjoy bridging full-...

I need an experienced .NET developer—five years or more working hands-on with C# and SQL Server—to step into an existing web application and keep it moving forward. The solution is already live and in daily use, so you’ll be working against a real-world codebase, not a green-field prototype. The core stack is ASP.NET (a mix of MVC and newer .NET Core services) with a SQL Server back-end. I rely on Entity Framework for data access, Git for version control, and a straightforward CI/CD pipeline. You should feel comfortable reading and refactoring legacy code, designing new features that slot cleanly into established patterns, and optimising T-SQL when a query starts slowing things down. Key things I’ll be asking you to do: • Review and refactor existing mo...

I'd love to connect and discuss potential collaboration opportunities.
I need an experienced .NET Core developer to plug full FASTag capability into my existing parking management platform. The RFID readers are already in place and streaming tag IDs; what’s missing is the software layer that talks to the FASTag service provider and folds those events into our business logic. Here is what the work entails: • Entry and exit processing – build secure REST endpoints that receive the tag read, validate it against the provider’s API, open the barrier, and persist the transaction with status codes for later audit. • Reconciliation and reporting – create automated, scheduler-driven jobs that pull settlement files, match them to our local ledger, flag discrepancies, and generate daily CSV-based reports. Beyond those core items, th...
I need a Windows-based application that talks directly to our Additel digital pressure gauges and Hydratron transducer, captures live pressure-temperature data, and drives the entire hose pressure-test workflow to NATA and current Australian Standards. The program must let a Technician log in, select a hose specification, enter temperature and target pressure, then automatically calculate the correct test duration and pass/fail limits. While the test is running it should stream readings from the instruments, display them in real time, and store everything in a SQL Server database. Once complete the software must produce a pressure-versus-time graph, compile all critical measurements, and generate a tamper-proof test certificate that satisfies NATA formatting requirements. Acceptance crit...
I’m extending our existing web-based application to cover the full accounts-receivable cycle. The new module must sit inside the current web app, so please plan your code to use the same tech stack, database, and authentication flow that is already in place. Core workflow • Finance reviews each quotation request that the team already creates in the system. • From that same screen Finance can produce a Invoice from system or from other application and upload the invoice against that quotation request and choose the due term (Net 0, 10, 30, 60, 90, 120). Support team will review it and click to send the invoice to client from application. • Issued invoices appear in a master list; any request that is still “uninvoiced” lives on its own page for quick fo...

I am launching a new web application and want the entire backend built in F#. The project must include rock-solid user authentication and two external API integrations: a payment gateway for transactions and social-media endpoints for sign-ups and data sharing. You will have full control over the technology stack on the .NET side, so feel free to suggest frameworks such as Giraffe, Saturn, SAFE Stack or any other F#-friendly tools that help us move quickly while keeping functional principles intact. The frontend can be whatever you are most comfortable with (Fable, React, Svelte, etc.) as long as it talks cleanly to the F# services you create. Key goals • Secure authentication: registration, login, password reset, JWT/session handling and role management. • API integratio...

My Microsoft Lists setup relies on several Power Automate flow triggers, yet two problems are slowing the team down: the flows sometimes fire on the wrong data and, at other times, they fire only sporadically. In addition, the SharePoint connections these flows depend on are now breaking at random moments. I need you to jump in immediately, identify the root cause, repair the faulty logic, and re-establish the SharePoint connections—all within the next 12 hours. Expect to work inside Microsoft Lists, Power Automate, and SharePoint Online; once you are done, every trigger should launch only when the correct item criteria are met and should do so consistently across repeated tests. Deliverables will be accepted when: • All affected flows run against the correct data set, w...
I need a bespoke recruitment platform that carries an applicant from first contact right through to payroll, all inside one fluid workflow. The core functionality has four pillars: • A robust Applicant Tracking System that lets me capture, parse and progress every application while maintaining a clear audit trail. • Smart Interview Scheduling with calendar sync (Outlook, Google, Apple), automated reminders and simple drag-and-drop re-booking. • Full Onboarding Management so new hires can sign documents, complete checklists and gain system access without paperwork bottlenecks. • Allocations & Payroll tools that assign hires to cost centres, calculate pay components and export clean data to my existing payroll engine through CSV or an open API. The system mu...
The core of my pets-services platform is already running on C#, ASP.NET Core and SQL Server, but only part of the roadmap is complete. I need a developer who can dive into the existing repository, understand what’s been built so far and then work alongside me, sprint by sprint, until we launch. and after we launch stay with me to develop it more. Where things stand • Current status: partially developed. Key models, some controllers and basic pages are live, but several workflows still stop at stubs or placeholders. • Guidelines: I have an architecture outline, UX wireframes and a list of required endpoints; however, I’m open to your recommendations on best practices, performance tuning, and UI polish. What you’ll be picking up – Clean up and extend...
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 ...
I need a developer who has already completed a Malaysian MyInvois / e-Invoice integration to plug that same expertise into our web-based EMR (ASP.NET C#, Microsoft SQL Server). The immediate goal is automated invoice generation: every time a consultation, treatment or ancillary service is saved in the EMR, a compliant e-Invoice must be created in the background and transmitted to the LHDN MyInvois gateway without any manual touch points. You will work directly in our existing codebase, expose or consume the necessary REST endpoints, handle authentication and digital signing, and persist the MyInvois response so finance staff can retrieve the PDF or XML from inside the EMR UI. Please bring along any helper libraries, middleware components or stored-procedure strategies you have already pro...
