Oscar A.

Former Senior Developer at Angel Studios (millions of users). I build full-stack web and mobile apps with Next.js, React Native (Expo), Supabase, Node.js, and Stripe. I specialize in solo projects — owning everything from frontend to deployment.

⚡ Next.js Development: I build fast, SEO-optimized web applications with Next.js, TypeScript, and Tailwind — leveraging SSR/SSG for performance and search visibility.

📱 React Native & Expo: I create cross-platform mobile apps from a single codebase that deploy to iOS App Store, Google Play, and web.

🗄️ Supabase & Backend: Full backend development with Supabase (auth, storage, realtime, edge functions), Node.js, Express, GraphQL, and tRPC.

💳 Third-Party Integrations: Seamless integration with Stripe, Clerk, Twilio, SendGrid, and other APIs to power your app's core features.

🚀 Solo Full-Stack Ownership: I manage entire projects end-to-end — frontend, backend, integrations, CI/CD, and deployment to Vercel, Digital Ocean, or your preferred platform.
