Hey👋, I'm Berk —
I build enterprise-grade
software.

Software engineer based in Istanbul, building the kind of quietly reliable systems that thirty-thousand people use every day without thinking about them — backends, integrations, and the middleware that keeps the lights on.

01 / About

A little about me

I'm a software engineer focused on building enterprise applications, backend services, and system integrations using .NET and React.

Most of my work lives on high-volume internal platforms — HR systems, SSO, LMS integrations, automation workflows — the kind of software a business actually runs on. I care about clean, maintainable code, sensible data models, and solving real problems without over-engineering them.

Recently wrapped up two years at Zorlu Holding, where I contributed to 15+ enterprise projects supporting 30K+ users across the group's companies. I'm currently between roles and open to new opportunities — full-time, contract, or freelance.
