Summary
🤩
RockstarJohn Chilton is a seasoned software engineer with 15 years of experience specializing in research software, reproducible bioinformatics workflows, and DevOps for data-intensive science. Based in State College, PA, he is a co-founder of the Common Workflow Language ecosystem and an active contributor to the Galaxy Project, where he has improved backend tooling, training materials, and deployment automation. His work spans full-stack contributions—from CSS and presentation tooling for training materials to robust error handling, logger recovery, and dependency management in CWL reference implementations. Equally comfortable writing job-script extensions and Conda integrations as he is configuring cloud-ready BioLinux images and system services, he brings practical, production-focused engineering to scientific software. A quirky problem-solver, he jokes that he “turns McDonald’s hash browns into pull requests,” hinting at a pragmatic, resourceful approach to complex community-driven projects.
