Amazon Detail Page

At Amazon, I'm the front-end technical lead for A+ Content Manager. The tool allows sellers and vendors to create rich content that best tells their product story and add personalized branding to their product detail pages on Amazon. The application has over 68,000 daily active users who publish content to 20 million products on Amazon.com each month. It's supported in 21 marketplaces around the world with multiple locales in each.

The app is used by companies including Nike, Sony, Fossil, Adidas, Microsoft, and Bose.

While working on this application, I write React with TypeScript, CSS-in-JS (Emotion), and use Redux for state management. I also use Redux-Saga for data fetching.

Key Contributions

Platform & Architecture

• Led multiple teams of engineers to migrate the app from three disparate design systems to a single unified system used across 20 code repositories.
• Reduced Babel config complexity by 86%, eliminating 25 dependencies and enabling migration to SWC or ESBuild for 10–20x faster builds.

Developer Experience

• Created two Vite plugins to be used by 1,500+ internal teams. One is now maintained by a Principal Engineer and reduces their local dev time by ~40%.
• Root-caused and resolved a critical CI/CD bottleneck in the app’s version set, reducing build times by 65% from an average of 32 minutes to 13 minutes.
• Implemented HMR (hot module replacement) for React components, reducing local dev times for the engineering team by ~66%.

Product Impact

• Authored the technical design doc and led a team of engineers to implement GenAI content creation tools. Users generate 81,000+ phrases and 58,000+ images every month with an 85% adoption rate.
