About John Baker

I have extensive experience building software that ships at scale — from open-source IDE features used by millions of Java developers worldwide, to real-time control systems for one of the most complex laser facilities on earth, to AI-powered enterprise SaaS serving global HR organizations. At Oracle (14+ years), I architected AI agent features for Oracle HCM Cloud, built REST APIs that increased adoption by 20%, and created a Dockerized WLS/HCM environment that cut team setup time by 50%. I also built a log-exception search tool that reduced diagnosis time by 40% — and led the team\'s full migration from Oracle ADE to Git. At Lawrence Livermore National Laboratory, I modernized $25M+ in enterprise applications and built Java UIs for the National Ignition Facility\'s real-time control system — mission-critical software supporting one of the world\'s most powerful laser arrays. At Sun Microsystems (nearly 12 years), I shipped core NetBeans IDE features — SQL History, Spring Web Framework UI, Visual Web database tools — used by the global Java developer community. I also served as QA Lead and volunteered as a JavaOne Hands-On Labs instructor for three consecutive years. What I bring: Full-stack depth: Java, REST APIs, React, Docker, Spring, Hibernate, SQL, JavaScriptProven AI/LLM integration in production enterprise SaaSConsistent record of measurable impact — 20–50% improvements across adoption, setup, and diagnosticsTechnical mentorship and leadership without losing hands-on coding depth Open to Senior or Principal Software Engineer roles in the SF Bay Area — full-stack, backend, or cloud-focused. j••••••••@gmail.com
