Faster internal tools, and better matches for interns.

I moved 3 internal tools to Next.js apps hosted on AWS, cutting page load times by 40%, and replaced manual release steps with deploys through AWS Amplify.

I also built server-rendered apps with React Query and Next.js that match interns with 300+ companies using machine-learning models, improving matching accuracy by 25%.

  • 40%faster page loads, after moving internal tools to Next.js on AWS
