During October 2025, Cha0s worked on the electron/electron repository, focusing on improving shutdown reliability across Electron’s multi-process architecture. By removing an early 'killed' check in the termination signal handling logic, Cha0s enabled the application to process multiple signals such as SIGINT and SIGTERM more reliably. This change reduced shutdown flakiness and improved stability for both the main runtime and child processes. The solution was implemented using Node.js and JavaScript, with an emphasis on robust back end development and process management. The work was delivered as a focused, traceable fix, enhancing maintainability and user experience during application termination sequences.
