WebCore contributor
Summary
Primarily a CSS engine contributor in WebCore, with the bulk of the work concentrated in css-conditional-5 `@container` queries (condition parsing, comma-separated lists, serialization), anchor positioning, and media query serialization, plus a secondary line in Site Isolation covering remote intersection-observer propagation across frames. The security-relevant work isn't a specialist pattern — it falls out of object state-lifetime bugs in adjacent code: Canvas2D state-stack handling (a filtered-drawing path that saved state unnecessarily, and an unwind-on-destruction fix) and a ResizeObserver crash triggered by observing the same element more than once. Systematic-variant candidate: duplicate observer registration and unbalanced canvas save/restore stacks, both of which surfaced here within weeks of each other and plausibly recur in the other observer types and in the Site Isolation remote-observer plumbing.
