I’m a Senior Android Developer with 6+ years of experience building, modernizing, and maintaining Android applications using Kotlin, Java, Jetpack Compose, MVVM, Retrofit, Firebase, SQLite/Room, and REST API integrations. I have worked on complex mobile products involving payment workflows, PAX/FEITIAN terminals, NFC/RFID/EMV transactions, custom libraries, ad monetization, and Google Play releases.
I’m strong in taking ownership of legacy projects, improving app performance, fixing critical bugs, optimizing API communication, and delivering stable production-ready apps. I have also mentored junior developers, collaborated directly with clients, and helped teams improve delivery speed and code quality.
I’m looking for a Senior Android Developer / Android Engineer role where I can contribute to scalable mobile apps, modern Android architecture, clean UI/UX, and high-quality product delivery. What sets me apart is my mix of deep Android development, payment system experience, debugging skills, and ability to handle projects from concept to release.
