Software that runs in production

I take the code I write to production and keep it running.

Yavuz Çelik

I'm an engineer building end-to-end production software in the enterprise .NET ecosystem. Web (ASP.NET Core), mobile (React Native/Expo), desktop (WinForms) and Windows services — I've shipped production-grade products on all four. My specialty is integrations connecting Logo and Bay.t ERPs to e-commerce, payment, marketplace and logistics platforms. I'm pursuing an M.Sc. in Data Science & AI at Sakarya University, working on OCR/NLP-based industrial monitoring systems under TÜBİTAK 3501.
