Hey there! I'm Antônio

I turn any idea into a complete product, top to bottom.

I build

Full stack developer and infrastructure enthusiast. Front end, back end, desktop and DevOps, in whatever framework the project calls for, or none at all.

What I do

I work end to end across the product lifecycle, from the interface to the infrastructure.

Modern frontend

React, Astro, Vite and Tailwind, integrated with modern design libraries. Interfaces that are intuitive and fast.

Robust backend

APIs and services on Bun and Elysia built to scale, plus third-party integrations, payments and authentication.

Infrastructure & DevOps

Docker, CI/CD, Cloudflare, AWS and Railway. The whole lifecycle, until it runs in production.
