Descripción

I build web products that work — fast, clean, and ready to scale.

My stack revolves around Next.js, TypeScript and Supabase, and I've been

using it to ship real products: right now I'm part of the team behind a

legal tech startup, where I handle everything from the database to the UI.

Before that, I spent a year freelancing and delivering full projects on

my own, which taught me how to move fast without cutting corners.

On the side, I maintain an open-source e-commerce template built with

Next.js, Supabase and Stripe that's collected 200+ GitHub stars, not

because I promoted it, but because people found it useful.

What I can help you with:

— SaaS products and MVPs from scratch

— AI-powered features and apps using Vercel AI SDK

(OpenAI, Anthropic, chatbots, copilots, custom integrations)

— E-commerce with Next.js, Stripe and Supabase

— Admin dashboards and internal tools

— Performance optimization for existing Next.js apps

I write about what I build too, my Next.js articles have reached

10,000+ reads on Medium.

Available in English and Spanish. Remote only.
