Full Stack Developer

Full Stack Engineer with 4+ years shipping production web and mobile apps that clients actually rely on — not just prototypes. I build across the whole stack: React and Flutter on the front end, Node.js/Express and MongoDB (plus Firebase Cloud Functions) on the back end. What that looks like in practice: • Built and published 4 cross-platform apps on the App Store and Google Play, maintaining a 99.8% crash-free rate through disciplined code review and performance tuning. • Led a 4-person team building a multi-app astrology & e-commerce platform (1,100+ commits, PR-based workflow) with real-time VoIP audio/video consultations via WebRTC and CallKit, localized across 15+ languages. • Cut a React app's load time from 4.2s to 1.8s (Lighthouse 92/100) and reduced bundle size 35% via code-splitting and Redux optimization. • Drove a 25% lift in merchant sales and 20% jump in user engagement on a grocery commerce app through better UX and a crash-free, scalable architecture. • Designed secure REST APIs with JWT auth, automated CI/CD pipelines (cutting deploy time 17%), and integrated payment gateways and real-time systems end to end. I care about reliability, speed, and measurable results. If you need someone who can own a feature from API design through App Store release — and leave it faster and more stable than they found it — let's talk.
