I've spent 7+ years building React/TypeScript applications. At ServiceNow, I built real-time simulators rendering live data across 3,000+ stores with continuous updates — the same kind of real-time, data-dense UI that trading dashboards demand. I also achieved a 3x performance improvement on critical pages and designed shared component architectures deployed across 3,000+ deployments. At G2K, I built the entire frontend architecture from scratch in React — it served 5K+ daily users and held through 3 major releases. I care about the details that make a trading UI trustworthy: performance, responsiveness, accessibility, and polish. When users are making financial decisions, the interface can't lag, break, or confuse.
