At ByteDance, I planned testing for Jianying PC and supported more than 20 releases without a P4+ incident attributed to the team. By standardizing content and processes and adding oversight, I helped reduce the escape rate by 50% and improve regression efficiency by 60%.
At Tencent, I worked on real-time audio and video services, including TRTC. I helped build its quality assurance system from 0 to 1, established more than 1,000 baseline cases, and developed automation covering 95% of the total cases and 100% of P0 cases.
I also contributed to TRTC CI/CD pipelines, working with platform colleagues on environment and pipeline improvements. More than 20 components were connected, and the work helped standardize the path from self-testing to release.
At Didi, I tested the server-side food delivery dispatch engine, built its continuous integration environment, and developed test tools. I also developed the backend for an automated troubleshooting platform that cut common issue investigations from minutes to seconds.
