Usama Sadiq

I'm a React Native & Full Stack Developer with 4+ years of professional experience building and shipping 15+ production-grade mobile and web applications. I specialize in cross-platform mobile development using React Native and Expo — from initial architecture to App Store and Google Play Store deployment. My work involves deep integrations with Supabase (auth, real-time database, edge functions), RevenueCat (subscription flows, Apple & Google server-to-server notifications), and TypeScript-first development practices. On the web side, I bring solid experience in Next.js, Node.js, Express.js, MongoDB, PostgreSQL, and REST API development — having delivered full-stack solutions across multiple client projects, including remote work for a US-based company. I also build workflow automation solutions using n8n — including WhatsApp bots, AI integrations, and custom business automations that save teams hours every week. If you're a startup or business struggling with a slow or outdated website, a missing or broken mobile app, or manual workflows eating up your team's time — I can help. Whether you need a web platform, a cross-platform iOS & Android app, or smart automations that run on their own — I build it the right way, on time, and without the back-and-forth. What I bring to every project: → End-to-end ownership — from architecture decisions to store deployment → Production mindset — clean code, performance, and real-world reliability → Clear communication — I understand requirements quickly and deliver on time → 4+ years across 4 companies — stability, depth, and diverse exposure Currently open to: ✦ Freelance mobile, web & automation projects ✦ Remote clients worldwide DM me with your project idea — I'll get back within 24 hours.
