Jan 1, 2025Month: 2025-01 — Focused on stabilizing CI for protected branches in electron/electron. Delivered a concurrency control fix that ensures only a single CI build runs at a time on protected branches, addressing race conditions that previously caused flaky pipelines. The change reworked the concurrency group handling and canceled-in-progress logic to improve build stability and throughput. This work reduces pipeline noise, lowers debugging effort, and supports faster shipping of critical changes.
