At BRANEF Innovation & Technology, I build and maintain GovTech applications for health surveillance and government operations across Brazilian states. The platforms support millions of end users.
On systems including SISVISA, PRODESP, and SISAMB, I developed features for sanitary licensing, electronic petitions, and public health process analysis. I also optimized SQL Server queries, improving response times by up to 60% on critical endpoints.
I led architecture refactoring using Clean Architecture, DDD, and SOLID principles, reducing codebase maintenance time by about 40%. My work includes C# and ASP.NET Core solutions, Razor Pages, and integrations with government APIs such as SEFAZ.
Running my own e-commerce ventures gave me a product and business perspective. I understand CAC and conversion rates, and aim to build software that addresses real business problems.
