Vandecarlos Santana

Fourteen years building software for banking, healthcare and logistics — Santander, BMG, a financial super app, and four healthcare systems. I started auditing medical claims in 2014. Today I build local AI, service agents, and process automation, focused on claim denial recovery in healthcare.
