I build and ship production apps with React Native (Expo) and Next.js: 8 products for startups in 6 countries, 3 of them live on the App Store and Google Play.
If you have an MVP built with Lovable, Cursor or Claude Code that now needs to hold up in production, or a mobile app that has to reach the stores, that is the work I do every day.
WHAT I DELIVER
- Mobile apps with React Native / Expo: EAS builds, store submission, OTA updates, offline-first sync
- Web platforms with Next.js (App Router) on Vercel
- Backends on Supabase (Postgres, row level security, Edge Functions) or Node.js / Express
- Payments and subscriptions with Stripe
- AI features with OpenAI, Anthropic and Gemini APIs, tool calling and MCP
- AI-built MVPs taken to production: code audit, security, multi-tenant data isolation, tests and CI/CD
RECENT WORK
- Investamind (Puerto Rico): investing-education app live on the App Store, with Face ID sessions, a realtime community and subscriptions
- UR POV (South Africa): local discovery app for iOS, Android and Huawei, built from scratch and still maintained
- Horus Surgical (US): AI patient-education platform for cataract surgeons, migrated from Supabase/Vercel to AWS
- Anchor (US): offline-first task planner with SQLite sync, subscriptions and an admin panel
- Festival PRO (UK): one React Native codebase shipping two branded festival apps
- EstudialoAI (Spain): AI study tutor on Next.js + Gemini with Stripe plans
HOW I WORK
- Claude Code is part of my daily workflow for speed, and I review and test every change before it ships
- Weekly demos and clear written updates. Fluent English, based in Argentina with full overlap with US hours
- Top Rated Plus, 4,300+ hours on Upwork
