Senior React Native Developer | Mobile App Consultant
I'm Syed Ali Hasan Gilani, a senior react native developer who ships production apps end-to-end — from architecture and native module bridging to App Store / Play Store release. I've shipped fintech, real-estate CRM, and social apps used by real people every day.
Senior React Native Developer Who Ships Measurable Results
Cross-platform iOS & Android engineering with React Native, TypeScript, Redux, and GraphQL — from architecture and native modules to App Store release and team leadership.
I'm a Senior React Native Developer with 5+ years building production, cross-platform apps for iOS and Android — including a real-time background geolocation app and a location-driven real estate platform. My stack centers on React Native, TypeScript, Redux (Toolkit/Saga/Thunk), GraphQL, REST APIs, and Socket.IO.
Past releases have delivered +35% app speed and +20% user retention. I've also led and mentored engineering teams in Agile/Scrum environments, driving a 15% increase in team productivity — owning everything from architecture and native module bridging to App Store / Play Store release.
Currently open to full-time and contract React Native roles.
Apps I've built that are live right now.
Every project below is shipped and publicly available on the App Store and Google Play.
Mashreq Pakistan
// Digital Islamic banking app
A production React Native banking platform for Mashreq's Pakistan launch — instant account opening, debit card management, bill payments to 4,000+ billers, fund transfers, and biometric-secured 24/7 banking, built on Redux Saga, REST APIs, and CMS-driven content.
BatchLeads
// Location-aware real estate platform
A location-driven real estate app that surfaces nearby properties in real time as users move or drive past a road — combining live geolocation with REST API integrations for lead discovery, skip tracing, and outbound campaigns.
PrayerLog
// Daily salah tracking & habit app
A daily prayer (salah) companion app that helps users log each of the five daily prayers, track streaks, and stay consistent — engineered with React Native performance best practices for a fast, reliable experience across devices.
Serendipity
// Real-time background geolocation app
A real-time user-tracking app that maintains accurate background location updates even when the app is killed, powered by react-native-background-geolocation. The real-time data layer syncs live location between mobile clients and backend services via GraphQL and Socket.IO.
5+ years across fintech, SaaS, and consumer apps.
