🤩
RockstarLeon Sorokin is a computer scientist and front-end engineer in Chicago with 15 years of experience building performant, usable web interfaces and developer tools. He contributes to high-profile open-source projects—from Grafana’s GraphNG and rustc-perf’s interactive graphs to small, highly optimized utilities like dropcss and uFuzzy—where he combines UI/UX polish with careful low-level refactors. Leon frequently rewrites core parsers, tightens selector logic, and prototypes fast visualizations (uPlot), demonstrating a willingness to touch both internals and presentation to deliver measurable gains. He brings a pragmatic philosophy about abstraction and a focus on accessibility and benchmarking, preferring minimal, elegant solutions that scale in practice.
