Brex Engineering with Cosmin Nicolaescu

Brex is a credit card company that provides credit to startups, mostly companies which have raised money. Brex processes millions of transactions, and uses the data from those transactions to assess creditworthiness, prevent fraud, and surface insights for the users of their cards. Brex is full of interesting engineering problems. The high volume of transactions requires data infrastructure to support all those transactions coming through the platform. As a credit card company, Brex needs to integrate with credit card networks and banking systems. There are internal systems for applications such as dispute resolution. Cos Nicolaescu is the CTO at Brex. He joins the show to discuss engineering at Brex, the dynamics of a credit card company, and his strategies around management. It was an instructive look inside of a rapidly growing fintech company.
