Akbank · Senior Android Engineer Android, written for production.

Muhammed Ali Kocabey.

I build native Android systems that ship in banking: architecture, security, and the shared infrastructure other teams build on top of. Two concrete examples: an in-house NFC identity-verification SDK that replaced a licensed third party and has been live since February, and a KSP navigation codegen running in production org-wide. Alongside that I keep Aspectify and SecureCheck open source, write up what I learn, and record a podcast.

What I'm on right now

Akbank Mobile · navigation module

After the NFC flow shipped, I built KSP-based codegen for the navigation/router module. It's now in 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.

  1. Senior Android Engineer

    Akbank T.A.S. (via Veripark)

    Jan 2026 - Present
    • Wrote Akbank Mobile's NFC identity verification SDK from scratch; live since Feb 2026. Replaced a licensed third-party solution.
    • 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 KSP-based build-time codegen for the navigation/router module; shipped org-wide in production.

  2. Senior Android Developer

    Akbank T.A.S. (via Veripark)

    Feb 2024 - Jan 2026
    • 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.

    Akbank T.A.S. (via Veripark)

    Feb 2023 - Feb 2024
    • Built parameterized UI components like CalendarSelectable and DoubleOption; picked up by several feature teams.
    • Contributed to the static-analysis pipeline, encryption standards, and secure-coding practices.

  4. Android Developer

    Altamira Digital

    Oct 2022 - Feb 2023
    • Built five smart-life and loyalty apps end to end with modular MVVM and REST APIs: Zorlu World, TAV Passport, 42 Maslak, Emaar, Nidalife. All met Play Store compliance.
    • Cut runtime issues and crash rates on high-traffic apps in production, and added secure session handling for loyalty and location-based promotions.

  5. Android & iOS Developer

    Comodo / Xcitium

    Jul 2021 - Oct 2022
    • Owned a cross-platform mobile security app on my own, across Android/Java and iOS/Swift: antivirus scanning, runtime threat detection, device integrity.
    • Cut threat-detection latency by about 25% by moving syncs to scheduled background services and trimming the on-device scan path.

  6. Founder & Developer

    ScoreUpp

    Jan 2019 - Jun 2021
    • Built an NLP analytics platform that pulled sentiment and categories out of Play Store reviews, using BERT, SymSpellPy, and custom classifiers under the hood.
    • Built the MVP in Python (Flask backend, NLP pipeline) with a lightweight Android frontend, cut support requests by 50% through automated review flagging, and took it into beta with 200+ early adopters.
