At Digienge Tecnologia, I worked on the HDM Platform, a multi-tenant SaaS for customer success and finance. I made sales tracking withstand campaign spikes, scaling load-test throughput from about 20 to 1,400+ sales per second, and optimized database queries that had been slowing customers’ work.
I modeled PostgreSQL data to reconcile payment gateways while keeping each company’s data isolated, and applied authentication, rate limiting, and encryption across the platform. I also put semantic search over customer data and an MCP server for AI assistants into production.
My projects include a Java fraud-detection system that placed 26th of 270 participants in Rinha de Backend 2026, plus event-driven alerting and infrastructure examples. At MedMais, I developed PHP/MySQL internal systems and improved slow queries. I completed a degree in Systems Analysis and Development at Vianna Júnior.
