Rockstar🎓
Top SchoolForest Fang is a Staff Software Engineer in San Francisco with a decade of experience building scalable data platforms, interactive visualizations, and ML tooling at companies like Stripe, Airbnb, and BlackRock. He combines deep distributed-systems expertise in Scala/Java, Hadoop and Spark with a designer’s sensibility for high-throughput, low-latency visualizations using D3.js, R/Shiny and WebGL. A Spark contributor and creator of a Spark t-SNE implementation, he’s known for removing boilerplate via metaprogramming and advancing developer ergonomics (including an sbt plugin he presented to the NYC Spark meetup). His open-source contributions span widely used front-end and tooling projects—eslint, vite, swc and esbuild—reflecting strong full-stack skills and attention to developer experience and TypeScript interoperability. Collected work shows a pattern of optimizing pipelines for 10–100x speedups and translating complex, TB-scale data into intuitive interactive products.

Contributions summary:Forest primarily contributed to bug fixes and feature updates within the ESLint codebase. Their work included allowing array spreads for the `prefer-object-spread` rule, enabling no tokens after the `return` keyword, and adding a "consistent" option to the `array-element-newline` rule. They also addressed an issue with object destructuring in the `prefer-const` rule and fixed various other minor issues across different rules, indicating a strong understanding of the project's architecture and coding standards.
