I build AI-augmented full-stack products, from marketplaces to multi-tenant platforms.

What I'm looking for

I'm looking to build and ship production products where AI-augmented engineering, end-to-end ownership, and close collaboration with product and design can create measurable business impact.

I'm building and running Wello, a two-sided marketplace connecting wellness professionals and clients in Rio de Janeiro. As co-founder and solo engineer, I've shipped booking, Pix checkout, a professional dashboard, and an admin back office using Next.js, TypeScript, Supabase, Tailwind CSS, and Vercel.

At Sportheca, I built the complete white-label front-end layer for Blox, rendering tenant-specific branding and content at runtime. I also delivered a bespoke website for a major Spanish football club serving roughly 100k monthly users and reduced deployment time by 60%.

I was promoted from Senior Front-End Engineer to Tech Lead, where I led planning and review cadences, introduced code review and automated testing practices, and mentored junior developers.

My work spans digital banking, micro-frontends, Node.js services, payments, and end-to-end freelance delivery. I use Claude Code, custom subagents, MCP tooling, and parallel worktrees as core infrastructure for shipping production software quickly.
