I turn complex ideas into shippable mobile products.
I'm Mamun — a Senior Mobile App Engineer with 7+ years building Flutter and React Native apps for global clients. From multivendor marketplaces to enterprise ERP, I care about clean architecture, measurable performance, and clear communication.
I led mobile for the Dokan and WP ERP ecosystems, and today I work independently — partnering with teams like EduLaabs and CoderTig, and with founders on Fiverr, Upwork and LinkedIn, to launch products people love to use.
- Clean, feature-first architecture
- Performance & 60fps by default
- AI-assisted delivery with Claude & Cursor
- End-to-end: build → CI/CD → store launch
-
"Ship fast, but never sacrifice architecture."
— My engineering principle
