/about

Who is Orhan?

I write code and try not to break things in production. Been at it for 4+ years mostly building APIs, cloud stuff, and web apps that banks and tech companies actually use.

I'm into making things work better. Faster APIs, cleaner code, smoother UX. The usual developer stuff, but I actually care about it.

Outside of code, I'm usually exploring new tools, simplifying side projects, or just tinkering with ideas that keep me curious.
