BIO
Co-founder & CTO at Rapidfolio (S26), where we use AI to automate the most complex financial processes with self-evolving, always-compliant, fully-auditable workflows no one else is building. Previously built two banks from scratch: founding engineer at Sable (S19, shipped in a record 3 months, pre-AI) and Seen, where I rebuilt the entire infra for the Snap Finance acquisition, built the credit decisioning engine and scaled to serve hundreds of thousands of customers.
