What I'm looking for

I’m interested in backend engineering opportunities in fintech, banking, SaaS, and enterprise software. I’m open to international remote work or relocation with employer-sponsored work authorization.

At Sicredi, I engineer Java and Spring Boot microservices for POS operations, supporting precise financial, tax, and accounting workflows. I also developed backend solutions for a delinquency reduction initiative that recovered over R$ 30 million within one year.

My work has included financial systems at TIVIT and judicial management systems at Extreme Digital Solution - EDS, iTeam, and Softplan. I’ve developed REST APIs, integrated enterprise systems, and contributed to modernizing legacy software, including a Delphi-to-C#, React, and GraphQL migration at Softplan.
