Mohammad Jahangir

Mohammad Jahangir — Riyadh, Saudi Arabia

React Native Developer

React Native is the mobile framework behind every shipped app in the portfolio: Opperiq's field-operations app, Kafoo's loyalty app, NavGo's ride-comparison app, and Top Influencers Content's iOS/Android apps. Each has different constraints — offline-tolerant GPS tracking, camera-based AI verification, bilingual RTL/LTR text, third-party API aggregation — solved within the same React Native codebase pattern.

What this looks like in practice

  • Geofenced attendance and live GPS tracking in Opperiq's field app
  • Camera-based AI face/selfie verification (YOLOv8, InsightFace) integrated into a React Native screen flow
  • Bilingual Arabic/English UI in Kafoo, including diagnosing an iOS-specific CoreText font-fallback bug
  • Redesigning Kafoo's dashboard header and partner rewards screens for a more premium visual treatment
  • Shipping Top Influencers Content to both the App Store and Google Play

Frequently asked

What React Native apps has Mohammad Jahangir built?

Opperiq's field-operations app, Kafoo's loyalty app, NavGo's ride-comparison app, and Top Influencers Content's iOS/Android apps — all React Native, all in production.

Has he solved platform-specific React Native bugs?

Yes — for example, an iOS-only Arabic text rendering bug in Kafoo caused by CoreText font fallback, which required a platform-specific fix rather than a shared-code change.
