Summary
👤
Senior🎓
Top SchoolKeith Smith is a Senior Principal Software Engineer based in Raleigh, NC, with over 35 years in software and a recent focus on emerging technologies and decentralized identity. He has led architecture and development at IBM on Hyperledger Fabric and Fabric CA, drove Verify Credentials and SSI work using zero-knowledge proofs, and now applies that expertise at Discover Financial Services. A pragmatic systems thinker, Keith combines deep security and cryptography experience—from OS and TCP/IP security to blockchain trust frameworks—with hands-on backend and DevOps contributions to widely used Hyperledger projects like indy-sdk and fabric-samples. He’s equally comfortable designing cloud and multi-region services as he is implementing low-level crypto/token flows, and he brings a track record of turning complex security protocols into production-ready, interoperable solutions.
