About

A bit about me

I'm a software developer from İzmir with 8+ years of experience building web applications and backend systems on the .NET stack, from hospital information systems to retail e-commerce backends. On the side, under my personal brand Cordelia Software, I design, build and publish cross-platform mobile apps with .NET MAUI, backed by ASP.NET Core APIs that I host and operate myself on Linux.
