Summary
🤩
RockstarJason Dillon is a Principal Software Engineer with 19 years of JVM-centric systems and platform design experience, blending deep Java/Kotlin expertise with a first‑language fluency in Linux, infra-as-code, and CI/CD. He specializes in taking complex, high-leverage problems from current state to shippable end state—prioritizing operability, survivability, and low ceremony over process theater. Jason has driven platform evolution at companies like Sonatype and Walmart, built critical CI/CD tooling and repository systems, and contributed to notable open-source projects including JLine, Groovy, Jansi, and Resty-GWT. Comfortable as a hands‑on principal IC, he pairs tactical implementation with architecture and small-team mentorship, and has architected both backend call-flow engines and JS/bytecode analysis prototypes. He treats AI tools as cognitive extensions—using them to accelerate design exploration and reduce bike‑shedding—and has worked remotely effectively for nearly two decades. Based in Oakley, CA, he prefers remote engagement with on-site collaboration for kickoffs and complex sessions.
