Summary
👤
Senior🎓
Top SchoolDavid Lee is a Senior Frontend Developer with 11+ years building high-performance, cross-browser web applications for finance, public sector, and enterprise SaaS. He combines deep mastery of vanilla JavaScript internals—prototypal inheritance, closures and execution context—with practical expertise in TypeScript, React and Angular to deliver robust SPAs and hybrid apps. His career spans companies from TD Securities and City of Toronto to Intuit and Manulife, where he has repeatedly improved UI performance, implemented real-time features, and refactored legacy codebases. David is comfortable architecting client-side systems and shipping production-ready code while working in Agile teams or independently. Beyond typical front-end skills, he has a solid backend and data background (Node.js, Java, WebSocket, SQL) that helps him bridge API and UI concerns. Based in Old Toronto, he maintains an active GitHub presence and a penchant for solving subtle browser behavior and performance issues that others often overlook.
