Akbank · Senior Android Engineer

I turn vision into code.

Muhammed AliKocabey.

I build native Android for banking. Beyond architecture and security, I also build shared infrastructure that other teams work on. For example, I wrote the NFC identity-verification SDK from scratch to replace a bought-in vendor; it's been live since February. The KSP navigation-codegen POC I built was then matured into production by the framework team. On the side I keep Aspectify and SecureCheck open source, write about what I learn, and record a podcast.

$ whoami

Hi, I'm Muhammed Ali. I build Android for banking, where mistakes aren't an option. Because there's real money and people's identity behind the code, I own the work from start to finish.

I like hard problems and solid architecture. I share what I learn as open source, writing and a podcast, which is why Aspectify and SecureCheck are public.

What I'm on right now

:codegen· KSP · build-time

Letting the compiler write navigation.

I built a POC that generates the navigation graph at build time from @Destination annotations via KSP; the framework team matured it into production, now used across feature teams.

Akbank Mobile · navigation module

After the NFC flow shipped, I built a KSP-based codegen POC for the navigation/router module; the framework team took it to production org-wide.

Aspectify

Handles cross-cutting concerns like logging, retry, cache and timeout through a single annotation. Built on Kotlin Reflection and Dynamic Proxy.

:migrate· RxJava → Coroutines / Flow

Modernized the tech while it kept running.

Migrated the app's async layer from the legacy library (RxJava) to modern Kotlin flows with zero user-facing disruption. Less code, fewer crashes.

Akbank T.A.S. (via Veripark)

Wrote Akbank Mobile's NFC identity verification SDK from scratch; live since Feb 2026. Replaced a paid third-party vendor.
Built NFC eID and liveness-based identity-verification onboarding for KYC, using liveness as an anti-spoofing control, delivered under fixed regulatory deadlines.
Wrote the shared Hilt multibinding patterns and the common network-response architecture used across feature modules.
Built a KSP-based build-time codegen POC for the navigation/router module; the framework team took it to production org-wide.

Akbank T.A.S. (via Veripark)

Migrated more than 8 financial modules (investment flows, SIM block, corporate admin, limit management) to MVVM + UseCase, holding around 85% unit-test coverage with static analysis.
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.
