🚀 I design Android apps using Kotlin, Compose, and modular patterns — with a strong focus on long-term maintainability and security.
🎯 I enjoy writing clean, reusable code that simplifies both development and collaboration.

Hi, I'm Muhammed Ali Kocabey 👋
Android developer with 4+ years of hands-on experience, mostly in fintech and enterprise-scale apps. I specialize in Kotlin, secure architecture, and testable modular code.

• 🧩 Specialized in Kotlin, Clean Architecture, Modular Systems, Jetpack Compose (in OSS projects).
• 🔑 Focused on secure coding, scalable architecture, and lifecycle-aware test utilities.
• ✨ Creator of Aspectify, a small library I built to handle cross-cutting concerns like retries and logging — with minimal boilerplate.
• 📘 I write about Android architecture and Kotlin development in both Turkish and English on Medium.
• 🎧 Host of Shaping the Future of Android, I turn selected blog posts into short podcast episodes — sharing real-world tips and reflections from my work in Android development.
• 🌍 Open to remote roles or relocation, especially in Europe, the US, or Dubai.

⚠️ In my enterprise role at Akbank, I use a custom declarative UI framework (not Jetpack Compose), tailored to internal design systems and CI/CD requirements.

• ✅ Refactored and reused the NFC verification flow in 4+ feature modules, improving testability and SDK integration time.
• 🛠️ Delivered flows like SIM unblocking and admin unlock with encrypted sessions and secure architecture.
• 📆 Created reusable UI components (e.g., CalendarSelectable, DoubleOptionView) from scratch.
• 🔄 Led the migration PoC from RxJava to Coroutines, later standardized across multiple modules.
• ⚖️ Introduced lifecycle-safe coroutine utilities used in 15+ test cases.
• ⚒️ Took initiative in deprecated API replacements (e.g., onBackPressed) with modern, high-order solutions.
• ⚡ Integrated time-critical SDKs (e.g., NFC & Liveness) under production deadlines.

• 🔄 Exploring Kotlin Symbol Processing (KSP) and Compiler Plugin tooling.
• 🛠️ Enhancing legacy enterprise codebases with secure, modular Kotlin architecture.
• 🔍 Working on better coroutine testing tools and writing about real-world performance issues in UI layers.

• ✨ Aspectify: A modern, modular AOP Framework for Android & Kotlin
  → Started as an experiment in modular AOP, now helps me abstract retries/logging in large-scale apps.

• 🔐 SecureCheck:
  → A showcase security app with 25+ checks like root, SSL pinning, Frida/Xposed, SafetyNet and more — all wrapped in a modular Clean Architecture setup.

• 🏦 Akbank Mobile (Enterprise, Private):
  → Delivered modular fintech flows (Investment, SIM Block, Corporate Admin, 129 Unlock, Holiday Access) with MVVM, encrypted session management, and test utilities.

• 💎 Smart-Life & Loyalty Apps:
  → Developed and maintained multiple loyalty apps (TAV Passport, Zorlu World, ALiving) with secure session handling and RESTful APIs.

• 🛡️ Comodo Mobile Security:
  → Designed and implemented mobile antivirus and scan features on Android & iOS.
