I build enterprise .NET, Angular, cloud, and database solutions for scalable web platforms.
BrazilWhat I'm looking for
I've built enterprise reporting solutions and client-facing portal features for ProScore's renewable energy platform using .NET Core, React, SQL Server, Oracle, and AWS S3.
At Máxima Tech, I developed Angular and .NET Core applications, APIs, and microservices integrated with ERP systems. I delivered an invoice PDF workflow used in marketing emails to over 20,000 customers and led a testing initiative that reduced bugs and errors by over 50%.
I bring 10+ years across software engineering, technical support, and QA, with hands-on work in Oracle, PostgreSQL, Docker, AWS, automated testing, and AI-assisted development. I'm seeking a remote international backend or full stack role from Brazil.
