What I'm looking for

I'm open to relocation or remote international roles where I can build scalable backend platforms, lead architecture decisions, mentor engineers, and work across fintech, payments, onboarding, or logistics domains.

At PagBank, I build the API-based account-opening platform used by enterprise clients and lead architecture decisions as the team’s technical reference. I’ve developed payments services for split payments, payment connectors, gift-card issuance, and flexible routing and reconciliation for e-commerce partners.

I also led backend development for Return Manager, a reverse-logistics platform, and created the team’s first QA environment for its monolith and related services. Across fintech, research, and web development, I deliver REST APIs and event-driven workers using Java, Kotlin, Node.js, PHP, AWS, Kubernetes, Terraform, Kafka, and RabbitMQ while mentoring engineers.
