Edgar Lee
Summary
🤩
RockstarEdgar Lee is a Vice President and Head of Software Infrastructure at PDT Partners in New York with 11 years of experience building distributed systems and container tooling. He brings hands-on engineering pedigree from Netflix and Docker, where he created cloud-backed build languages, a CI-managed artifacts service, and a novel approach to reproducible container images — even exploring IPFS-based image distribution. An active open-source contributor to core projects like containerd and BuildKit, he focuses on runtime internals, image import improvements, and builder efficiency. Edgar blends strategic platform leadership with deep systems work—refactoring critical push flows, fixing metadata and mount semantics, and building parallel test frameworks in Go—to keep large platforms reliable and reproducible.
