Top SchoolAndrew Pennebaker is a seasoned software engineer with 15 years of experience building secure, portable infrastructure and developer tools, currently publishing open-source projects as Root at YelloSoft. He blends back-end and DevOps expertise—contributing to high-profile projects like HashiCorp's Packer and enhancing database migration tooling—alongside hands-on work in Rust, Go, and cloud-native systems. His career spans platform engineering, DevSecOps, and senior engineering roles where he raised QA through IaC, led Go tutoring, and built SCA/SAST tools for improved security posture. Andrew coaches and mentors teams, drives cross-team modernization efforts, and frequently pairs with junior developers to elevate practices. Now planning a transition into Scrum management, he brings a rare combination of deep technical craft and a curiosity for improving how teams work. Based in Milwaukee, he’s equally comfortable prototyping low-level VM input handling as he is automating multi-ISA container builds.
