What I'm looking for

I’m open to full-time or contract remote roles and international relocation with visa sponsorship. I can work through an Employer of Record, overlap with European working hours, and bring experience working remotely with a US-based team.

At Avetics Global Pte Ltd, I own the rewrite of a mission-critical drone-control app, now in production. I built it with Kotlin and Jetpack Compose, integrating the DJI Mobile SDK for live camera feeds and autonomous flight.

I defined the app’s multi-module architecture and built real-time hardware communication and offline-first data handling. I also set up testing that replaces the DJI SDK and socket layers with fakes, and mentored the six-person Android team as we adopted Compose, Hilt, and unit testing.

Before Avetics, I worked on fintech, health, and consumer apps at GrowFolio and Samsung R&D Institute Bangladesh, and founded Power GP BD Limited, where I delivered Android applications for phones, tablets, and Android TV. I’m an early adopter of Kotlin Multiplatform and Compose Multiplatform, and I use AI-assisted development tools in my work.
