At EmpreElas, I develop and maintain features across a production multi-tenant commerce SaaS, including its admin, reseller, and public storefront areas. I build backend logic with Supabase Edge Functions and PostgreSQL, keeping pricing, stock, and order rules on the server.
At Grupo Nasli, I maintained and evolved the company's vehicle inspection system across the backend and frontend, and provided internal IT support.
For Hells Brindes, I designed and built an ERP that covers finance, invoicing with NF-e issuing, deliveries, inventory, suppliers, HR, and a client portal. I evolved it into a multi-tenant SaaS with tenant-scoped data, role-based permissions, and white-label settings.
I also implemented JWT authentication with TOTP 2FA, audit logging, and a 73-test backend suite for the ERP. My other projects include a shared billing and subscription API and a training app REST API.
