Mark Vayngrib is a CTO and co-founder with 14 years of hands-on engineering and product experience, currently building a blockchain‑agnostic KYC network that gives banks and customers portable ownership of identity data. He architects serverless, containerized systems that run Node.js everywhere—backend, mobile and web—combining AWS Lambda, Docker, and React/React Native to deliver pre-integrated KYC SDKs and enterprise bot frameworks. An MIT‑trained engineer, he blends deep systems work (DHT, UDP, test automation) with practical mobile and data modeling experience, contributing fixes to notable open-source projects like bittorrent‑dht and multiple React Native tooling repos. He’s equally fluent in devops and integration—sanctions/PEP screening, document verification and payments—and has a track record of shipping full-stack platforms (Urbien) and rapid MVPs. Quirky side: his GitHub bio says he’s “building some hilarious stuff,” which matches a history of pragmatic hacks that bridge Node core modules into React Native.
