Rockstar🎓
Top SchoolJoseph Harrison-lim is a full stack software engineer with nine years of experience building resilient web platforms, leading client-facing features, and optimizing Postgres and Kubernetes at scale. He moves fluidly between Rails, React, Scala, and systems work—routinely shipping performance and security improvements that have produced multi‑order query speedups and increased platform stability. At Pixlee/Emplifi he led product tagging delivery, integration efforts, and internal tooling while mentoring teammates and managing releases and on-call incidents. An active open-source contributor, he has enhanced the popular Helix modal editor and spends spare time reading compiler codebases, contributing to Rust Analyzer and compiling his own Ruby with a personal flag. He’s currently focused on platform and web engineering at Hive.co in Toronto while privately developing a Rust compiler aimed at advancing type inference and compile-time evaluation for a dynamic language. This blend of production discipline, deep systems curiosity, and practical tooling improvements makes him a reliable engineer who also delights in low-level experimentation.
