About Me

Profile Picture

Jamie Luong

I’m a Frontend Developer experienced in building and optimizing high-traffic web applications. My work has focused on developing responsive interfaces, reusable UI components, and dynamic features using JavaScript, HTML, and CSS within production environments.

I’ve led frontend initiatives that improved user engagement, implemented analytics-driven optimizations, and integrated APIs to support complex business requirements. Although much of my recent work has been within e-commerce platforms, my primary focus has always been frontend architecture, performance, and user experience.

I’m now looking to grow into frontend roles beyond e-commerce, where I can contribute to scalable product development and continue expanding my expertise in modern frameworks and engineering best practices.
