Engineering Manager building scalable teams and production AI infrastructure for fintech, payments, and travel tech.
BrazilWhat I'm looking for
I’m an Engineering Manager with 8+ years in software and 5+ years building and scaling product teams in fintech, payments, and travel tech. I lead cross-functional squads of up to 12 engineers, prioritizing delivery, technical excellence, and engineering growth through an ownership culture and measurable business impact.
Over the past year, I built production AI infrastructure end to end—hybrid RAG, multi-provider LLM orchestration, and Claude agent pipelines—giving my teams a rare edge. I’ve driven real outcomes like reducing production incidents by 40%, tripling deployment frequency via DORA metrics, cutting tech-debt by ~90%, and improving mobile quality with 99.95% crash-free sessions, while strengthening observability, hiring, onboarding, and technical governance.
