What I'm looking for

I'm open to remote full-stack opportunities where I can build enterprise, embedded, and web solutions from architecture through deployment while leading technical standards and mentoring teams.

At MULTTI, I build ATM and kiosk software with C#/.NET, Avalonia UI, ASP.NET Core APIs, React, and Azure. I set architecture standards, lead technical work, mentor teammates, and align delivery with stakeholder requirements as a proxy Product Owner.

Previously at Hábil Informática, I modernized enterprise management systems from legacy .NET Framework applications to .NET 8/9 architecture. I built microservices, fiscal document modules, clinic management features, SQL Server databases, reports, and dashboards while improving query performance by up to 80%.

I also optimize web systems, including PHP and PostgreSQL reporting and monitoring at Revisão Online. I enjoy delivering full-stack products from architecture through deployment.
