About this gig

I build full-stack web apps with Next.js and React, deployed on Vercel no monthly fees, no maintenance costs, no lock-in. You get clean code, mobile-first design and a production-ready app that's yours to keep.


I've shipped two live SaaS products from scratch, so I know how to turn a messy requirement into something that actually works in production.

Full-stack dev and co-founder of Leaf SaaS. I spent 5 years inside a real ERP company — support, processes, migrations, critical incidents — before going full-time building products. That background shows in the code: I think about edge cases, data integrity and operational flow, not just the happy path. Two live SaaS products: Leaf Delivery (white-label ordering with WhatsApp, iFood, PIX and KDS) and LeafDFe (Brazilian tax document automation with SEFAZ). Both built end to end by me. Stack: Next.js, React, TypeScript, Node, Python, PostgreSQL, Prisma.
