02 — ABOUTHow I think about the work

Good software is
quietly capable.

I work as a Backend Developer at Kapadokya University, building institutional systems, REST APIs, integrations and AI-powered tools. I also build independent products where an idea needs to become something real.

My background moves between Python, Django, Flask, PHP, Laravel, React and database architecture. The stack matters, but the outcome matters more: a dependable system that makes someone’s work easier.
