TÜRKİYE / OPEN TO REMOTE

From architecture
to production.

I'm Harun Erkam Balı. I build and operate software systems end-to-end — bringing backend engineering, infrastructure and R&D together.

C# / ASP.NET CORE / DJANGO / FASTAPI / MSSQL / POSTGRESQLA little more about me

Good software doesn't stop at the API. It needs thoughtful data models, a usable interface and infrastructure you can depend on.

I am a backend-focused engineer with 3+ years of experience designing, building, deploying and operating production systems. I develop C#/.NET APIs and web applications with ASP.NET Core and Entity Framework Core, alongside Django, FastAPI and Go services. My work spans authentication, payments, invoices, automation and external integrations, using MSSQL and PostgreSQL across Linux and Windows Server environments.

I'm drawn to R&D projects where performance, reliability and emerging technologies come together to solve practical problems.
