Noé Medina Calixto
@nomedinacalixto
I lead Node.js banking platforms and deliver Central Bank-compliant payment and onboarding systems.
BrazilWhat I'm looking for
At B.uni Banking, I lead a four-person development team and delivered Pix Automático, MED, BC Protege and the alphanumeric CNPJ migration under Brazilian Central Bank deadlines. I also rebuilt customer onboarding with idwall, enabling public sign-up and 2,000 new accounts in its first week.
I've built back-end systems across fintech, energy, logistics, healthcare and education, from stabilising Flora Energia's serverless billing pipeline for a 50,000-customer energy-credit platform to developing freight, e-commerce and controlled-product integrations at MBLabs. My core stack is Node.js, TypeScript and AWS, and I enjoy working on regulated products, payments, integrations and data-intensive operations.
