At Ewally, I optimized the company's most critical system, eliminating performance issues, deadlocks, and race conditions, and was promoted from Senior Software Engineer to Tech Lead. I lead a team of four and build fintech products across backend and frontend.
I also built regulatory reporting integrations for financial authorities in Brazil using requirements from official documentation. Before Ewally, I developed management systems, administrative portals, and mobile applications at Innove Consultoria de Resultado, and created a management system for a preparatory course through independent and freelance work.
