Siye Liu is a Senior Software Engineer based in Seattle with 7 years of experience building core browser and text-editing features at Microsoft Edge. He is a Chromium committer who has driven Windows-specific integrations such as Text Service Framework and spellchecker engines, plus cross-cutting improvements to HTML5-compliant editing and direct manipulation. Proficient across Python, PHP, C/C++, and JavaScript, he blends systems-level C++ work with web-platform testing, having contributed tests and API adaptations to the high-profile web-platform-tests (WPT) project. His academic background spans computer science, applied mathematics, and economics from the University of Washington and an MS in Computer Information Systems from Boston University, informing a pragmatic, data-aware engineering approach. Comfortable owning architecture and low-level integrations, he also brings hands-on experience designing human-subject experiments and building measurement tooling from his research background. Colleagues rely on him for robust, standards-aligned solutions that bridge browser internals and real-world web compatibility.
