Hi, I'm

Sam

AI/ML | Cryptography

Most engineers build locks. Some build lockpicks. I study the hands that hold them.

Full-cycle developer with experience shipping intelligent autonomous and decentralized systems. I enjoy building solutions that make everyday tasks and processes easier. I also like reading systems synthesis and convergent engineering research.

AI/Data engineer, Vodacom. Previously AI Agentic Engineer intern at Nethermind where I contributed to Agentic and ZK engineering initiatives.
