Summary
Andy Barnes is a Senior Manager at GitHub with over 10 years of hands-on experience in support engineering, systems administration and technical documentation. He has progressed through multiple senior support roles at GitHub, specialising in enterprise deployments, code security tooling (Code Scanning, Dependabot, Dependency Graph) and identity integrations (LDAP/SAML/SSO) across Linux, Debian/Ubuntu, cloud (AWS/Azure) and desktop platforms. Known for turning complex operational problems into clear processes and customer-facing documentation, he routinely bridges support, engineering and sales to improve product reliability and onboarding.
