Message

At Halalbooking, I’m the sole mobile engineer responsible for the React Native application across iOS and Android. I built end-to-end deep linking and a two-way communication layer between React Native and WebView, connecting web and native workflows.

I also built mobile push notification infrastructure with Firebase Cloud Messaging, APNs, and Customer.io, and integrated EAS Update into an existing bare React Native application. I’ve owned 40+ production releases across iOS and Android.

At FitGrid, I led a frontend team of 2–3 engineers while staying hands-on with React and React Native development. I designed a two-way client messaging experience integrated with Twilio and built a standalone event-ranking web application with React and TypeScript.

Earlier, I developed production web and mobile applications at FitGrid, AgileEngine, Akvelon, and Nix Solutions. My work included modernizing frontend build systems, integrating APIs, and developing React Native applications with native iOS and Android functionality.
