About this gig

Need a .NET backend that won't fall apart in production? That's what I do.

AI tools generate code fast but it often breaks under real traffic, leaks money on slow queries, or can't be maintained. I build and rescue ASP.NET Core backends that hold up when real users show up.

I'm a backend developer with 4+ years on large-scale production systems. I focus on what AI can't reliably do: clean architecture, correct data modeling, and performance that scales.

What I do:

  • REST APIs in ASP.NET Core (C#) on Clean Architecture
  • Database design with PostgreSQL, MongoDB, Redis (EF Core)
  • JWT auth, validation, error handling, Swagger
  • Background jobs (Hangfire), payment & 3rd-party API integration
  • Performance & scaling: caching, query optimization
  • Fixing broken or AI-generated backends

Why me:

  • Real production experience code that survives real load
  • Clean, tested, documented code your team can build on
  • Clear communication in English and Turkish

Not sure which package fits? Message me your project and I'll tell you honestly what it needs.
