Junliang Huang is a versatile software engineer with 12 years of experience combining computer science, data science, and design sensibilities to build performant, user-focused web tools. Based in Ann Arbor and pursuing an M.S. at the University of Michigan, he has shipped front-end and full-stack work across high-profile open-source projects like Babel, Webpack, Angular, and Browserslist, contributing to REPLs, parser tooling, and cross-browser compatibility tables. He brings practical performance engineering and build/CI expertise—optimizing hotspots in Webpack, migrating Babel tooling to modern runtimes, and stabilizing CI for babel-loader—alongside hands-on DevOps experience deploying Dockerized apps to Kubernetes. His HERE Technologies internship delivered a multi-page, React-based map metadata interface with Okta auth and automated pipelines, reflecting a strong product-minded approach to engineering. Known on GitHub for projects including a popular ECMAScript compat table and AST explorer improvements, he blends attention to browser quirks with a designer’s eye from his art and design minor. Pragmatic and detail-oriented, he often surfaces subtle compatibility and tooling gaps that improve developer experience and runtime efficiency.
