I build resilient backend services for fintech, payments, and real-time platforms.
BrazilWhat I'm looking for
I've built production services for BREVYA, Caveo, and NYC Bank, improving payment reliability, supporting high-volume banking workloads, and delivering real-time platforms. My work spans Go, C#, Node.js, PostgreSQL, Redis, and message-driven architectures.
At Caveo, I improved payment success by 15% through end-to-end telemetry and audit records, and built a KYC validation pipeline processing around 1,000 new users monthly at a 98% validation rate. I also design resilient systems with Kafka, RabbitMQ, SQS/SNS, Azure Service Bus, Kubernetes, Terraform, Docker, CI/CD, caching, failover, and observability.
