In 10+ years of active development I've worked across the spectrum — from small SaaS to enterprise POS deployed across hundreds of stores. My core expertise is backend architecture in the .NET ecosystem — building scalable, maintainable, quietly-running systems.
Currently I work as a Senior Backend Developer at Colin's in Istanbul. I develop ERPOS — our enterprise POS — covering sales, returns, invoicing, and staff/customer modules; focusing on cache architecture, message queue refactoring, and performance optimization.
Outside work I focus on truly integrating AI tooling into the developer workflow. I've put Antigravity at the center of my daily process — using it across freelance work, side SaaS experiments, and content creation. Currently I freelance on Upwork, develop my own SaaS ideas, and work on various mobile apps.

I don't chase cool tech. Once you define the right problem, the solution is often already in plain sight — you just need to see it.
Don't write code you can't read 6 months later. Complexity is debt — I take it on only as much as needed.
I speak with numbers, not guesses. Profiler, APM, log analysis — no evidence, no decision.
Launch isn't the end. I watch how it's used in the first weeks and carry the learning to the next version.
If there's something to work on together — backend architecture, performance, .NET system renewal, or MVP development — write me.
