Jason Chen

Full-stack engineer with 8+ years of experience building enterprise-grade systems across frontend, backend, DevOps, mobile, and AI/LLM domains — 143 projects shipped, from factory automation platforms to AI-powered quality analysis tools and healthcare systems. Beyond the day job, I run my own self-hosted k3s production cluster solo: 3-server etcd HA, Longhorn storage, Prometheus/Grafana monitoring, and off-site disaster recovery, documented incident-by-incident in a 15-part write-up series. I also independently administer and maintain a self-hosted GitLab instance — runners, CI/CD pipelines, upgrades — end to end. I build my own tooling with Claude Code too, from a portfolio-generation pipeline to a macOS usage-tracking app, treating AI-assisted development as a first-class part of how I ship.
