About Me

// about_me.json

I'm a software developer based in Dhaka, Bangladesh, specializing in building exceptional digital experiences for both web and mobile.

With 3+ years of production experience, I've shipped apps used by real users across SaaS platforms, B2B tools, alumni networks, and community apps — including iOS App Store & Google Play deployments.

My toolkit spans React & Next.js for the web, React Native for iOS/Android, and Node.js / Express / MongoDB for backend APIs.

I'm also fluent with modern AI productivity tools — Cursor, Claude, ChatGPT & GitHub Copilot — leveraging agentic AI to ship faster and smarter.

Lead mobile engineer shipping production React Native apps to iOS App Store and Google Play — from architecture to final store submission.

▸Integrated biometric auth (fingerprint/face ID via react-native-biometrics), FCM/APNs push notifications, deep linking, and international + local payment gateways into cross-platform apps
▸Owned full App Store / Google Play release cycles — Xcode archiving, signing, TestFlight, App Store Connect review, Google Play Console staged rollouts, and EAS OTA updates between releases
▸Optimised heavy list rendering with FlatList + memo/useCallback, cutting frame drops on mid-range Android devices; used Flipper and Reactotron for profiling and network debugging
▸Introduced async MMKV storage (replacing AsyncStorage) and Reanimated 3 gesture-driven animations to elevate app responsiveness and UX quality
