Matt Sweeney is a support engineer and open-source backend developer with 20 years of technical experience, based in Chicago. He blends hands-on DevOps and backend work—contributing to high-profile projects like Jenkins, Spinnaker, and DefectDojo—with practical security-focused enhancements such as secrets management and vulnerability parsing. Comfortable across Python and Java ecosystems, he’s improved core CI/CD tooling, added cryptographic support to Apache Commons Codec, and helped harden scanning and plugin workflows. Matt pairs customer-facing support roles with deep code contributions, often fixing tricky file-permission, test stability, and compatibility issues that quietly keep platforms reliable. A General Assembly alum who mentors peers and enjoys front-end learning, he’s equally likely to be debugging production systems or photographing his dog around Chicago.
