B2G TAM mapped
Sanitized healthcare market intelligence pipeline covering 64.3M units, 759 buyer CNPJs, and 26/27 states.
Engineer by training, Revenue Architect by trade. From CAN-Bus interceptors to probabilistic S&OP engines, market data pipelines, and multi-agent LLM swarms. CAISR, LSS Black Belt, CEA ANBIMA, 5× MBA.
Best fit for roles that need business context, technical execution, and a calm adult in the room: Revenue Architect, RevOps/Data Lead, Solutions Architect, AI Automation Lead, AI Security/Risk Lead, or Fractional Tech Lead.
I've intercepted Toyota CAN-Bus frames at 3am, closed R$2M deals before lunch, and turned fragmented public data into board-level market intelligence. Same brain, different mode.
13 years across 7 verticals taught me that the best systems live where operations, data, and revenue collide. I build CAN-Bus interceptors with ESP32, design probabilistic S&OP engines for falsifiable forecasts, and orchestrate multi-agent AI swarms with equal fluency.
