About Wei Jie

Click here to download my CV.

I'm a cryptography engineer from Singapore, now based in Los Angeles. I work on zero-knowledge systems, smart contracts, and client-side optimisations. Before working as a researcher for Bain Capital Crypto and Geometry Research, I was an early member of the Ethereum Foundation's Privacy and Scaling Explorations team.

I'm especially excited by cryptographic protocols that empower users over centralised and opaque intermediaries. The world deserves open-source tools for privacy, secure collaboration, and verifiable computation, and I've dedicated my work to making this a reality.

What motivates me most is building systems that are decentralised by design and just on the edge of what's practical. I believe thoughtful engineering can turn bold ideas into systems that are scalable, impactful, and secure.

I'm looking for the most interesting and challenging problems at the intersection of deep cryptography and engineering. If you think I can help, please feel free to reach out.

My given name (Wei Jie) follows my surname (Koh) as per Eastern name order.
