I'm a software architect and engineering leader with 20+ years of hands-on experience building high-performance backend systems in regulated environments. Currently VP of Technology and cofounder at Paag, a Brazilian payments fintech.
Previously a Cloud Application Architect within AWS Professional Services. I work mostly on the harder problems — payment systems at scale, PostgreSQL under production load, compliance and AML platforms, on-chain forensics, and the occasional bit of homelab tinkering.
