About this gig

I build robust REST APIs and backend systems using C# and ASP.NET Core, from simple CRUD APIs to full solutions with JWT authentication and database integration (SQL Server, Entity Framework Core).

Whether you need a quick API for one entity or a complete backend with secure authentication and multiple integrations, I deliver clean, well-documented code you can actually maintain and build on.

What I offer:

  • REST API development in C# / ASP.NET Core
  • JWT authentication & secure endpoints
  • Database design and integration (SQL Server, EF Core)
  • Swagger/OpenAPI documentation
  • Clean, documented, production-ready code

(Optional add-on: I can also integrate an AI chatbot connected to your database using function calling ask me about it if you're interested.)

Message me with your project details and I'll get back to you with a clear plan and timeline.

I'm a Higher Technician in Software Development specializing in .NET backend technologies, including ASP.NET Core and Entity Framework Core — demonstrated through personal projects like a REST API for inventory management with JWT authentication. I also have hands-on experience in AI prompt engineering and chatbot design from a professional internship, including sentiment detection logic and escalation flows. I'm currently seeking my first professional opportunity to apply these skills in backend development and AI integration.
