Message

At Implanta, I develop and evolve corporate applications used by more than 400 active clients. I design modular .NET architectures using DDD, Clean Architecture, and CQRS.

I build REST APIs with ASP.NET Core, including authentication and integrations with external services. I also deliver web applications with Angular and TypeScript, and mobile apps with Flutter and Ionic.

At Geap Autogestão em Saúde, I developed and maintained systems serving more than 400,000 beneficiaries and created the Acompanhe sua Adesão portal. I also migrated the reimbursement system from VB.NET to Vue.js and .NET.

At UBEC - União Brasiliense de Educação e Cultura, I created a grade management system that reduced grade entry from days to minutes, built the Esperançar platform, and developed reusable NuGet packages and service integrations.
