PROFILE

Francesco Renzi

Developed advanced debugging capabilities for CI workflows across the ubicloud/runner and actions/runner repositories, focusing on backend enhancements using C# and network programming. Built and integrated a Debug Adapter Protocol (DAP) server to enable interactive workflow debugging, including step execution, variable inspection, and command evaluation. Introduced remote debugging features such as Dev Tunnel support and a WebSocket bridge for DAP over TCP, streamlining issue reproduction in distributed environments. Improved debugger lifecycle management and reliability by embedding DAP setup into job initialization and supporting pause-on-completion for job inspection. Emphasized robust software architecture, unit testing, and seamless developer experience throughout the work.
