About me
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.
