Akbank Mobile · navigation module
After the NFC flow shipped, I'm writing KSP-based codegen for the navigation/router module. Currently being rolled out org-wide.
Muhammed Ali Kocabey.
I wrote Akbank Mobile's NFC identity verification flow, live since February 2026. I also maintain two open-source projects on GitHub: Aspectify, an AOP framework for Kotlin, and SecureCheck, a security library for Android.

Jan 2026 — Present
Staff Android Engineer
Akbank T.A.S. (via Veripark)
- Wrote Akbank Mobile's NFC identity verification SDK from scratch. Live since Feb 2026; replaces a third-party solution that cost the bank $1-2M/year.
- Wrote the shared Hilt multibinding patterns and the common network-response architecture every feature team uses.
- Built KSP-based build-time codegen for the navigation/router module; rolled out across the org in production.

Senior Android Developer
Akbank T.A.S. (via Veripark)
- Migrated more than 8 financial modules (investment flows, SIM block, corporate admin, limit management) to MVVM + UseCase. Hit 80–90% test coverage per module.
- Wrote the RxJava → Coroutines migration PoC. The lifecycle-aware utilities I shipped run across the org's feature modules.
- Closed long-standing session and routing crashes on the admin and account screens.
