Summary
👤
Senior🎓
Top SchoolTommy Han is a Senior React Engineer based in New York with 8 years focused on modern front-end engineering and a multi-decade background across Java, Python, and full-stack systems. He currently drives React development at Salesforce and previously built reusable component systems, Next.js apps and real-time React/Redux identity verification flows at Rocket Auto and Intuit respectively. Tommy blends deep legacy systems experience—from financial services and large-scale caches to Java web services—with contemporary front-end engineering, allowing him to architect pragmatic integrations between browser UIs and backend verification or financial APIs. He has a knack for making complex behavior observable and explainable, exemplified by a devtool project that traverses the React Fiber tree and visualizes render performance. Colleagues rely on him for reusable component design, mentoring on A/B experimentation, and simplifying tricky verification workflows into maintainable solutions. His background in electrical/computer engineering plus recurring interest in teaching and explainability informs a methodical, test-driven approach to shipping predictable user-facing systems.
