At Alfameta Sistemas Específicos, I refactored a critical billing routine, cutting processing time from up to 10 minutes to a few seconds. I also replaced a third-party tax provider with an in-house solution using ACBr and worked across its legacy ERP, web SaaS, and automation systems.
I created GödelByte, a metadata-driven, multi-tenant ERP SaaS for small and medium-sized businesses, now in production with more than 1,200 automated tests. I build backend systems and APIs with Python, FastAPI, Java, and Spring Boot, with a focus on transaction consistency, testing, and versioned migrations.
