About Me
Senior mobile engineer. Production Android apps, and the systems behind them.
I'm Mahmud, a senior mobile engineer with production experience in Kotlin and Jetpack Compose, and Flutter for cross-platform work. I've shipped apps to Google Play for government agencies, enterprises, and my own products.
I build my own backend (Laravel, Node.js) rather than wait on one, so mobile features ship end-to-end without a handoff. On top of that, I run multi-agent AI systems that automate parts of my own development and release workflow.
