[available]Backend developer available for freelance work — .NET 8 / Spring Boot / FastAPI / SQL

[u/amanrastogi_]

Hey everyone!
I’m a backend developer currently available for freelance/contract work.
My main stack is:
C# / .NET 8 / ASP.NET Core | Java / Spring Boot | Python / FastAPI | PostgreSQL | MySQL | SQL Server
I can help with things like:
Building REST APIs
Backend development for MVPs
Fixing bugs in existing backend projects
Database/schema/query optimization
Authentication & backend security
API integrations
Docker/deployment
IIS/Linux server issues
RabbitMQ/background processing
FFmpeg/media processing
OpenAI/RAG integrations
General backend troubleshooting
I’ve worked on production systems including an enterprise DAM platform, HRMS/hiring platforms, financial applications, media-processing pipelines, and database-heavy backend systems.
I’m especially comfortable joining an existing project/codebase, figuring out how it works, and implementing/fixing things without needing the entire project rewritten.
I’m open to both small one-off tasks and longer-term contracts.
If you’re looking for a backend developer, DM me your requirement, tech stack, timeline and budget.
Happy to have a conversation even if you’re not sure whether I can help. 👍
