Joel Martin is a Principal Software Engineer and developer productivity leader with 21+ years building scalable infrastructure, cloud platforms, and developer tools. He has architected and shipped large-scale systems—from an API-driven test platform that can deploy millions of containers to full IaaS clouds and hybrid cloud orchestration—while leading technical teams at companies like Viasat, Equinix, and Supabase. Joel is an active open-source contributor (notably to make-a-lisp and noVNC/websockify), with hands-on expertise in systems, networking protocols, high-performance I/O, and language/runtime implementation. He combines deep low-level experience (device drivers, kernel bringup, cross-compilers) with modern cloud-native practices, functional programming, and property-based testing to accelerate team iteration velocity. Known for creating high-leverage tooling and specification-driven approaches (e.g., live-spec, instacheck), he repeatedly rescues and scales complex projects. Based in Duncanville, Texas, he pairs PhD-level rigor with a pragmatic, developer-first mindset.
