Mobile-First · Full-Stack Engineer

From schema
to store.

I'm Veli Kaan Çetinel — a mobile-first engineer with 10+ Flutter apps shipped to the stores, and the full-stack depth to build everything beneath them: schemas, APIs and workflow engines. Currently the technical owner of the ARES V2 re-platform at Destech Hasar (RS Servis).

Every layer, owned

Mobile is where I'm strongest — and I take responsibility for the whole path beneath it, from the tap on the screen to the row in the database.

Mobile

10+ Flutter apps shipped to the App Store and Google Play — a 3-in-1 tablet suite with five languages and RTL, BLE hardware pairing, background geolocation, CI/CD with Codemagic and GitLab.

Backend

Normalized schema design, dual-write migrations that reversed direction mid-flight, transactional outbox + HMAC integrations, workflow & document rule engines — and internal tooling that cut schema introspection from 94s to 1.9s.
