Full-Stack Developer building ControlaAí, a multi-tenant SaaS for food service with POS, inventory, finance, and NFC-e.

I designed and run ControlaAí, a multi-tenant SaaS used daily in real businesses, with POS, inventory, finance, delivery, and NFC-e integration. I also run a convenience store and beverage delivery business and a laundromat using systems I built myself.

Across projects including Zequinha ERP + Delivery and icGYM, I build web systems end to end and use AI to automate repetitive work, such as reading supplier invoices and filling stock entries. Before development work, I spent three years in R&D and management, where I created a franchisee relations department and used Power BI dashboards to support decisions.
