Summary
🤩
RockstarRay Xu is a Technical Product Specialist based in Hong Kong with four years of software engineering experience and a long background in consulting and business analysis. He blends product-focused delivery at WeBank with hands-on contributions to high-profile Rust-based JavaScript tooling like swc and oxc, improving JSX/TypeScript handling and implementing linter rules. Comfortable across full-stack and compiler-level problems, he has fixed tricky parsing and lexing edge cases and added semantic lint checks such as valid-typeof and no-function-assign. His trajectory from senior consulting and business analysis into technical product work gives him a strong mix of stakeholder-facing product skills and deep code-level expertise. Colleagues would note he quietly bridges product requirements and developer ergonomics, turning complex front-end compiler issues into reliable developer-facing features.
