What I'm looking for

I'm looking for PJ or remote opportunities where I can build and modernize critical Java backend systems, distributed integrations, batch processing, and financial payment flows while growing through end-to-end technical ownership.

I've progressed from intern to Full Stack Developer at FADESP/SEFA-PA, building and sustaining critical public-sector financial systems for collections, payments, PIX, bank reception, installments, IPVA, and fiscal current accounts.

I modernized bank-file processing with Java 17, Spring Boot, Spring Batch, Kafka, Apache NiFi, and MinIO. The architecture ingests files through SFTP and REST APIs, validates FEBRABAN layouts, stores metadata and files, and processes CNAB 240 flows asynchronously for payments, bank statements, and reconciliation.

I've also contributed to SEFA-PA's PIX and digital-payment capabilities, an initiative associated with 19.72% growth in state revenue.

My work spans business rules in Oracle/PLSQL, REST APIs, event-driven integrations, production troubleshooting, automated tests, CI/CD pipelines, containers, and on-call support. I enjoy taking ownership from technical design through deployment and production support in high-criticality transactional environments.
