Senior full-stack developer from the Dominican Republic. I build web products end to end with Next.js, TypeScript, PostgreSQL and Stripe, and I add AI features (Claude API) that stay reliable in real use.
- Full-stack web apps: Next.js, React, Node.js, PostgreSQL, Tailwind CSS
- Payments: Stripe subscriptions, signed webhooks, retries without duplicates
- AI features: document extraction, prompts, validation and fallbacks
- Mobile: React Native and Expo (Android)
- Quality: Jest, React Testing Library, CI, Lighthouse and Core Web Vitals
- PlantPal: offline-first plant care app (Expo, Next.js API, Postgres, push, subscriptions). Live on Google Play. Built with AI assistance.
- StoryKeep: Next.js and Postgres app with Stripe billing, webhooks, background AI jobs and PDF/DOCX export.
- Animal Adventures: a free, ad-free English/Spanish learning app for kids, built with React Native and Expo. Live on Google Play.
- D'Higuey Longanizas: online shop with React, Node, PostgreSQL and Supabase auth.
- More client work (CityRoomFinder, Discount Club and others) is private. See it on my website.
