##about01

Engineer working on web and mobile products, mostly in TypeScript. Interested in staying current with the toolchain without letting it become the job — the deliverable is a product that loads fast, ships often, and does not page anyone at night.

Graduated in Computer Engineering from İstanbul Teknik Üniversitesi. Since then: eight roles across agencies, startups and product teams in İstanbul, Lisbon and Delaware.
