About this gig
Looking for a reliable backend developer to build a clean, scalable
REST API? You're in the right place.
I'm a Full-Stack .NET Developer with hands-on experience designing
production-grade APIs using ASP.NET Core, Entity Framework Core, and
PostgreSQL. Currently I work on an enterprise project at DXC Luxoft,
so I understand what production-ready really means.
What I can build for you:
- Clean REST API with ASP.NET Core and C#
- Database schema design with PostgreSQL, SQL Server, or MongoDB
- JWT authentication and role-based authorization
- Input validation, error handling, async programming
- Full Swagger / OpenAPI documentation
- Docker containerization for easy deployment
- Unit tests with xUnit
- Source code with clear comments, following SOLID principles
Tech stack:
C#, ASP.NET Core, Entity Framework Core, PostgreSQL, Docker, JWT,
Swagger, xUnit.
Why work with me:
- Real enterprise experience, not just tutorials
- Clean, maintainable code you can extend later
- Clear communication in English
- On-time delivery, no ghosting

FAQ
Will I receive the source code?
Yes. All packages include full source code delivered via a Git repository or ZIP archive, with clear comments and a README.
Can you work with a database other than PostgreSQL?
Yes. I can also work with SQL Server, MySQL, SQLite, and MongoDB. Just let me know before ordering and I'll adjust the stack.
Do you provide deployment to a server or cloud?
Deployment is available as an extra service. I can deploy your API to Linux, Azure, or AWS with a basic setup and guide.
What if I need more endpoints than the package includes?
You can add the "Extra endpoints" option at checkout, or we can discuss a custom offer tailored to your exact scope.
Do you sign an NDA?
Yes. I'm happy to sign a reasonable NDA before we start. I have experience working in NDA-bound enterprise environments.
What do you need from me to get started?
A short description of your data model, the endpoints you need, any authentication requirements, and your preferred tech stack if you have one.
