What I'm looking for

I'm open to remote, hybrid, and relocation opportunities worldwide.

At Systems Limited, I architect and develop mobile applications for enterprise clients including Unilever, ABB, IGI Insurance, and Regeneron Pharma. I work across Flutter and Native Android, from requirements through deployment.

I led development of Abb Engage, a full e-commerce solution built in Flutter and Native Android that serves thousands of active users. I integrated payment gateways, order tracking, and third-party SDKs.

At Amid Tech, I built Kotlin-based Android apps including Hertz Driver App and Muslims365. For Muslims365, I engineered a custom native Azan plugin and an offline-capable Quran reading and audio-recitation experience.

Across my mobile development work, I’ve delivered 53+ apps published on Google Play Store. I hold a PMP certification and have mentored junior developers.
