My focus is simple: smooth performance, revenue generating apps, and code that can grow without breaking. I build fast, secure, and scalable mobile apps for Android and iOS using Kotlin, Jetpack Compose, and Kotlin Multiplatform.

I’ve spent the last 4 years helping founders and companies turn ideas into production-ready apps. My recent work includes ArmourVault, an offline-first file encryption app built from scratch with secure storage, custom cryptography, ML Kit, and seamless file handling, delivered without delays or scope issues.

What I’m best at

• Android Development (Kotlin, Compose, Java): High-performance UIs, clean modular architecture, MVI, Coroutines, Hilt.

• Cross-Platform Development (KMP): Shared business logic for Android + iOS without sacrificing native quality.

• Performance Optimization: Reduce crashes, eliminate lag, optimize networking, improve stability.

• Secure Systems: Authentication, encryption, data protection, offline caching.

• Payment Systems: Stripe, in-app purchases, subscriptions.

• Firebase: Auth, Firestore, Storage, Cloud Functions, analytics

• iOS development support through Kotlin Multiplatform or Flutter

Industries I deliver for

E-commerce, Fintech, Food Delivery, Productivity/SaaS, AI tools, Secure File Systems.

Why clients work with me

• Zero-drama communication

• Strong engineering background across Android, KMP, Flutter, and system design

• Ability to own both product thinking and technical execution

• Reliable delivery with clean, maintainable code
