Full-Stack Developer (.NET 8 / React Native/ Linux)

@talhaamin

I am an expert in c# microservices and react native both and can deliver quality work, i understand that you are interested in paying for only worked hours not on time spend understanding code.

@Microlent

Hello! What you’re describing is very much production work, not greenfield experiments, and that’s where I’m most comfortable. A mature .NET 8 microservice system with real users means changes have to be deliberate, tested, and shipped cleanly, not “try and see.” My focus would be squarely on the backend as you outlined. Extending existing microservices in C#, adding new APIs with clear contracts, wiring events correctly through RabbitMQ, and persisting data reliably in PostgreSQL. I’m used to containerising services, deploying to Ubuntu-based AWS setups, and pushing changes all the way to production without disrupting live traffic. For the sprint items, I can handle exposing and documenting new endpoints for the React Native app, tracking down and fixing the FCM notification issue at the service level, and integrating the chat component from the backend side so it behaves predictably under load. I pay attention to logging, error handling, and backward compatibility so mobile clients don’t break unexpectedly. I work independently, manage my own tasks, and communicate clearly about what’s done, what’s blocked, and what could be improved. I’m fine with the hands-on-only billing model and focused on delivering working code, not billable noise. If you want someone who can step into a live system and move it forward safely, I’m ready to start. Best Regards, Jenifer

Hello There!!! ⚜⭐⭐⭐⭐⚜(( Extend and stabilize a live .NET microservice backend for production scale ))⚜⭐⭐⭐⭐⚜ Working on a live production system where code ships directly to users requires discipline, clarity, and respect for what already exists. Your setup with .NET 8 microservices, React Native, RabbitMQ, and PostgreSQL on AWS clearly points to a backend first role focused on reliability and delivery, not experimentation. You are looking for someone who can step into a mature codebase, extend services cleanly, expose well documented APIs, and deploy with confidence. I have solid experience building and evolving .NET based microservice systems on Linux, containerising services, handling async messaging, and integrating APIs consumed by mobile apps. My approach would be to understand service boundaries first, then implement new functionality with minimal risk, clear documentation, and production ready testing so releases stay predictable. Three key areas I would focus on: • Extending .NET 8 microservices and shipping stable production code • Designing and documenting APIs consumed by the React Native app • Fixing FCM notification issues and integrating real time chat components If you want a dependable backend developer who owns tasks and communicates clearly, I would be happy to discuss the first sprint and priorities. Warm Regards, Farhin B.

@Appworldz

Hi, I work with production-grade .NET microservices and React Native apps on Linux-based AWS stacks, so extending your existing architecture and shipping stable features fast is very familiar territory. I can focus first sprint on backend-heavy work while keeping the React Native integration clean and non-disruptive for current users. For the initial 7–10 day sprint, the plan is to extend your existing .NET 8 microservices by adding the required RabbitMQ events and PostgreSQL persistence with proper unit/integration tests, design and document the new API endpoints, then integrate them into the current React Native flows without breaking existing behavior, and finally diagnose and fix the FCM notification problems while integrating a robust chat component with reliable message delivery, logging, and basic monitoring around both features so the new functionality is production-ready and observable from day one. What are the highest-priority APIs and FCM/chat issues you want solved in the very first sprint so we can define a clear, testable done-state ? ​ If you are open to a short technical call, a quick walkthrough of the current microservice layout, deployment flow, and existing API docs will help ensure safer, faster releases from day one. Regards Sahanaj

@sabaehsan

Greetings, I appreciate the opportunity to help you enhance your live production app. It sounds like you need a dedicated full-stack developer to extend your .NET 8 microservice architecture and develop new APIs, with a focus on reliability and clear documentation. I'll approach this by diving into your existing codebase, ensuring that I understand the current setup, and then efficiently adding the required features while maintaining high-quality standards. With my experience in C#, PostgreSQL, and RabbitMQ, I can tackle the enhancements you need, as well as fix the FCM notification bug and integrate the chat component seamlessly. I believe effective communication and a proactive approach to improvements are key to a successful collaboration, and I'm ready to take ownership of the tasks. Best regards, Saba Ehsan

@uzzairkhan

You need a reliable developer to expand your .NET 8 microservices and APIs. I will extend your backend with new, tested modules and APIs, addressing FCM notifications and chat integration. This approach prioritizes direct delivery of production-ready code. I will clearly communicate throughout, suggesting improvements as I build. This covers the described sprint deliverables. Any unforeseen complexities will be flagged immediately. Recently, I delivered a similar API extension for a financial services client, increasing their transaction processing capacity by 30%. Are your AWS credentials set up for immediate deployment access?

@Arshaqwajid

I’m a .NET developer experienced with microservices, PostgreSQL, and API design in production environments. I can extend your .NET 8 services, containerize them, wire events through RabbitMQ, and ship reliable APIs that integrate smoothly with your React Native app. I’ll also fix the FCM notification issue and implement the chat component with clean, testable code. Comfortable working on Ubuntu/AWS, I communicate clearly, work independently, and focus on stable deployments that add real value from day one.

@Julian29

Thanks for the clear brief. I can absolutely help, and I want to be upfront: at $6/hour, I can still deliver the work, but only if the scope is strictly limited to hands-on development with minimal support overhead (no architecture consulting, no deep research, no extensive onboarding). That said, I can help you with the immediate priorities: new API endpoints, microservice extensions, RabbitMQ wiring, PostgreSQL persistence, and production deployment, plus FCM notification fixes and chat integration—all in a stable, production-safe way. ✅ What I can deliver in the initial sprint Extend microservice modules with clean C# .NET 8 code and new endpoints Integrate RabbitMQ events across services Persist new data in PostgreSQL with migrations Deploy updated containers to AWS (Docker + ECS/containers) FCM notification bug fix and reliable delivery Chat component integration (backend + API + frontend hooks) ⚠️ What I need from you to move fast To start immediately, I’ll need: Repo access (read/write) AWS access (or CI/CD credentials) Current API docs / swagger FCM credentials and notification logs Chat provider details (if any) Next step If you’re happy to proceed, I’ll start by reviewing the codebase and immediately submit a sprint plan with clear milestones, so we don’t waste time. Reply “START” and send access details, and I’ll begin today.
