What I'm looking for

I'm looking for remote full-stack or backend .NET work where I can build scalable APIs and enterprise systems, collaborate with global teams in English, and contribute through clean architecture, performance optimization, and reliable delivery.

I've built and scaled enterprise software across Savage Global Marketing, 90TI, and Banpará, including financial ERP modules serving more than 6,000 corporate clients. I develop high-performance C# and .NET web applications, RESTful APIs, desktop applications, and responsive Angular and React interfaces.

At 90TI, I optimized SQL Server procedures and queries for sub-second execution while applying Clean Architecture, SOLID principles, and automated testing to reduce production defects. I've also worked remotely with US engineering teams, managing Azure DevOps CI/CD workflows and delivering secure systems for financial and regulatory environments.
