I'm leading React Native development for RAKBank mobile banking at Systems Limited, serving 1 million+ users across the UAE. I build secure, bilingual banking journeys for Payments, Loans, Credit Cards, Crypto trading, KYC, and Onboarding within a large Nx monorepo.

Across Systems Limited, CodeNinja, InvoZone, and AlphaSquad, I've delivered React Native and React.js products spanning fintech, enterprise software, logistics, POS, and real-time communication. I focus on reusable front-end architecture, Redux Toolkit and RTK Query state layers, reliable mobile releases, and high-quality engineering practices.
