Every merged contribution, listed and linked: open-source portfolio
Figures as of 13 July 2026. The DevStats link is live and will be ahead of the number above.
I audit Dynamic Resource Allocation for arithmetic and lifecycle bugs. It began with an int64 overflow in quota accounting, which I reported in kueue#12896, fixed across four merged pull requests, then found and fixed in Volcano.
That audit is now open across the ecosystem: overflow and panic bugs in Kubernetes core DRA (3 pull requests, 5 issues), a slice-bounds panic in CNCF container-device-interface, a nil dereference in KubeVirt, and quota-accounting problems in KAI-Scheduler. These are under review and not yet merged.
I want to help more people cross from using cloud native software to contributing to it: newcomer sessions in Mandarin and Taiwanese, and bilingual contribution walkthroughs drawn from real review threads. I completed LFC102 (Inclusive Open Source Community Orientation) in July 2026.
