Chi sono
Full-stack developer and solo creator of two live products: ShipSealed (open-source RLS tools + SaaS boilerplate for Supabase, with automated tenant-isolation tests) and Zingui (personal finance app with CSV/OFX import, LGPD compliant).
I deliver working, tested products — not just code. I also understand the wider landscape of a digital project (stores, mobile apps, AI automation, payments) and help you find the right solution first — fair pricing, scaled to your project.
If your project handles sensitive data or needs real automation, let's talk.
