Guillaume Charmes is a Director of Engineering with 14 years building and scaling cloud-native platforms, currently leading engineering at Immertec from Fort Lauderdale. A former lead developer on Docker and active Go contributor, he combines deep systems-level expertise (containers, signals, ptys, cross-compilation) with hands-on migration experience that repeatedly reduced costs and unlocked scale. He’s driven cloud transformations and microservice migrations at startups and enterprises (Magic Leap, SimpleReach, Agrarian Labs), and has led teams to adopt Go, Docker, and modern SDLC practices. Guillaume blends executive leadership with technical ownership—authoring Docker docs and contributing fixes to core projects—so he’s comfortable both shaping roadmap and shipping low-level code. An unusual strength is his cross-platform systems work (OpenBSD, Solaris, RISC-V) and tooling contributions that reflect a pragmatic focus on portability and maintainability.
