Rockstar🎓
Top SchoolTing-yu Lin is a Senior Software Engineer based in Portland with 13 years of professional experience and 11+ years as a committed developer specializing in browser layout, CSS, and rendering engines. At Mozilla he has driven core improvements in Gecko and Servo—implementing CSS features like column-span, scrollbar-gutter, shapes, and flexbox/fragmentation behaviors—and serves as a layout module peer since 2021. He contributes across languages (C++, Rust, JS, Python) and projects, from Gecko and Servo to ICU4X and web-platform-tests, blending standards-focused test work with low-level engine optimizations. Comfortable in both front-end layout logic and back-end engine plumbing, he has a track record of refactors that improve performance, maintainability, and cross-browser correctness. Notably, his open-source footprint includes thoughtful contributions to internationalization (UAX14 line breaking) and embeddable, memory-safe rendering efforts in Servo.
