Senior software engineer specializing in scalable, cloud-native systems for FinTech and e-commerce.
BrazilWhat I'm looking for
I am a Senior Software Engineer with 6+ years designing and delivering scalable distributed systems, particularly in FinTech and e-commerce. I specialize in functional programming with Scala, Rust and Go, and build cloud-native solutions on AWS and GCP for high-volume transaction processing.
My work has driven measurable reliability and product expansion at global tech companies, including maintaining payment systems that handle over 6M weekly transactions and delivering regulatory-compliant features like Stripe 3DS. I’ve designed microservices for financial reconciliation, automated partner payouts for tens of thousands of partners, and led migrations from monoliths to maintainable distributed architectures.
I focus on performance, observability and secure API-first design, and I enjoy architecting resilient platforms that scale. I bring pragmatic engineering, cross-functional collaboration, and a track record of shipping production systems at high availability.
