I'm a full stack developer. I build complete products, web apps, mobile apps for iOS and Android, and the APIs and databases behind them. Most developers can ship something that works. I ship things that work and feel considered: a checkout that responds the moment you tap it, a dashboard that loads instantly, a sign-in flow that doesn't feel like paperwork. One person handling every layer means no handoff gaps, no "that's a backend issue," and a faster path to launch. What I build: • Mobile apps for iOS and Android from one codebase. React Native and Expo, published to the App Store and Google Play • Full web applications, auth, dashboards, payments, admin panels, integrations • REST APIs, webhooks, and third-party integrations (Stripe, Meta/Instagram, OpenAI) • Databases and backend logic in Node.js, PostgreSQL, and Supabase • Front ends in React, Next.js, and vanilla JS + Vite, responsive, accessible, fast • Advanced interface animation with GSAP, Canvas, and WebGL when a product needs to stand out I've built 150+ interactive components and projects, and I record a short video of each one, so you can see how my work actually behaves, not just screenshots. Clear updates, honest timelines, and code your team can maintain after I hand it over. Tell me what you're building and I'll tell you exactly how I'd approach it.
