About

Who I am

Based in: Isparta, Türkiye
Time zone: UTC+3
How I work: Remote, end to end
Studio: Jante Creative, co-founder since 2023
Every day: Claude Code
Coworker: Oli, the cat

I live in Isparta, Türkiye and work remotely. My time zone is UTC+3, so my day overlaps with Europe and with US East Coast hours.

I am a co-founder of Jante Creative, a software and design studio, since 2023. I lead the engineering side and ship projects end to end: database, server logic, front end, payments, deployment and maintenance.

I use Claude Code every day and run Claude API features in production, such as reading invoices from a photo. My cat Oli is my coworker. He watches from the second chair.
