Summary
🤩
RockstarJerry Shih is a seasoned software engineer with 12 years of experience building and optimizing large C/C++ codebases across browsers, game engines, and deep learning compilers. He has deep GPU and 3D graphics expertise—implementing WebGL 2.0 in Firefox, tuning WebRender and video/texture pipelines, and shipping a DirectX-based real-time engine—alongside hands-on work on neural network frontends/backends and int8 inference optimizations. At SiFive he leveraged RISC-V vector extensions to accelerate crypto and math libraries, and his open-source contributions include high-performance crypto primitives for OpenSSL on RISC-V and texture handling improvements to Servo’s WebRender. Comfortable in Rust and assembly, he bridges low-level performance engineering with ML compiler code generation for custom accelerators, often improving memory footprint and runtime stability in production systems. Based in Taipei, he combines systems-level rigor with a practical track record of shipping cross-domain performance gains.

A GPU-based renderer for the web
Role in this project:
Backend Developer
Backend DeveloperContributions:62 commits, 32 PRs, 155 comments in 9 months
Contributions summary:Jerry primarily contributed to the GPU-based renderer for the web project, specifically focusing on the `webrender` module. Their contributions involved modifying the `resource_cache.rs` and `texture_cache.rs` files to add and handle different image data types, including external raw buffers and YUV formats, which required changes to the data structures within the `webrender_traits` module. They also addressed texture updating and rendering operations within the renderer.
