What I'm looking for

I seek senior mobile/React Native roles in fintech or telecom that value security, scalable architecture, CI/CD, and opportunities to lead and mentor teams.

I am a Senior React Native developer with over five years building secure, scalable mobile applications for banking, fintech, and telecommunications. I specialize in TypeScript, JavaScript, Redux, GraphQL, and robust API integrations.

At Mashreq and VOIS I led frontend squads, architected reusable libraries, and delivered production apps to Google Play and the App Store. I drove KYC/OCR integrations, implemented banking-grade security (OAuth2, JWT, E2E encryption), improved app responsiveness by 40%, and maintained high test coverage.

I mentor junior developers, champion Atomic Design and i18n, and prioritize CI/CD-driven delivery and developer productivity. I seek to lead technical direction and deliver secure, user-centered mobile experiences at scale.
