Android Developer | Kotlin & Java | Jetpack Compose • Firebase • REST APIs | Consumer App Specialist · Coimbatore, Tamil Nadu, India

I'm an Android Developer with 2 years of hands-on experience designing, building, and shipping consumer-facing Android applications to the Google Play Store — independently, end to end. I specialize in Kotlin, Jetpack Compose, Firebase, and REST APIs (Retrofit / PHP / Node.js), following clean MVVM architecture to build scalable apps across diverse domains. Apps I've built and shipped: 🎓 Aptitude Question & Answers — Interview prep app with optimized API integration (30% efficiency boost). 👶 Eduraan — Kids learning app with drag-drop, tracing, TTS, parental controls & gamified videos. 📖 Bible Quiz — Adaptive quiz engine with improved user engagement. 🏋️ Workout Zone / Yoga Zone — Fitness apps with shared backend & reusable UI. 🗺️ Smart Travel Guide — Real-time Map SDK + GPS travel assistant. 🎨 Kids Colouring : Art wall — Currently building, Jetpack Compose coloring app. As a solo developer, I've owned the full app lifecycle — architecture, UI, APIs, deployment and optimization.
