Tech Lead at Yooga, architecting POS and payment systems deployed across 1000+ restaurant clients in Brazil. Previously at QuintoAndar, where I cut logistics costs by 13% and drove CSAT up 16 points. Building TOPO Contabil — an enterprise accounting platform running 42 NestJS modules, 252 use cases, and a 16-state workflow machine, all in Clean Architecture. I ship production systems, not prototypes. Daily driver: Claude Code in the terminal. No IDE. No GUI. Just prompts and stdout.
