I'm a data engineer. I build data platforms at work and ship my own apps on the side.

How I build

I designed and run a team of AI coding agents, and I drive it from my phone by chatting with its orchestrator. The orchestrator splits the work across parallel Claude Code and Codex sessions on several accounts, and the other engine reviews every change. It runs Handlez end to end, makes its marketing videos and built this site.

17–25 October 2026 · 411 agent sessions · about 580 commits to HandlezHow it works →

About

I work as a data engineer in Istanbul, in the data team of a large group of companies: Fabric lakehouses, pipelines over SAP and plant production data from many sites, and the Power BI models on top.

In my own time I build products end to end, from the pipeline that feeds them to the app in the store. Three of them are above.

I studied Management Information Systems at Yeditepe University on a full scholarship and spent a semester in Warsaw on Erasmus+.
