Senior React Native and Expo developer. I've spent the last five years building production iOS and Android apps, usually as the only mobile engineer on each project, taking them from empty repo to live on the App Store and Google Play. Some of what I've shipped: Fitra360: an AI wellness platform that analyzes DNA, bloodwork, symptoms, and lifestyle data to generate personalized health and routine plans. FIXA: a car services and AI diagnostics app with camera-based tire scanning and Elasticsearch-powered search, in production. Gayar: Kuwait's first car parts marketplace. Three years in production with full ad-platform integration (TikTok, Snap, Meta, Google) and deep-linked campaigns. Other production work spans health insurance telemedicine, Saudi enterprise ERP (POS, inventory, geofenced HR attendance), university apps with campus security systems, and AI-assisted real estate platforms. The work tends to land in two buckets. New builds: production React Native + Expo apps from MVP through enterprise scale. AI features like health analysis, in-app assistants, image recognition, and smart recommendations. Healthcare and telemedicine platforms with video consultations, secure data, and prescriptions. Marketplaces and e-commerce apps with deep linking and full event tracking. Enterprise ERP, POS, inventory, and HR systems. Supabase, Firebase, and GraphQL backends (auth, RLS, realtime, edge functions, storage). Pixel-perfect UI from Figma, REST and GraphQL APIs, push notifications, in-app purchases, geolocation, maps, geofencing, deep linking. App Store and Google Play submissions end-to-end, including rejection appeals. Rescues: crashes, white screens, broken navigation. Performance issues like slow lists, laggy animations, high memory, slow cold start. Auth and session problems (Supabase, Firebase, OAuth, expo-auth-session). App Store and Play Store rejections. TestFlight build and distribution issues. Send a quick description, a Loom, or an error log. I'll come back with a clear plan, a realistic timeline, and what it'll actually take.
