I build web apps that load fast and feel good to use.

I'm Amit. I've spent 7+ years on React and Next.js front ends, and lately a lot of my time goes into AI tools and agent workflows. Below are a few things I've built, at work and on weekends.

Reelsmith

An AI director for Instagram Reels: give it a story, your clips and a song, and it cuts a finished 9:16 reel. It logs every shot, writes two treatments and picks one, cuts on the beat, then renders frames to critique and fix its own edit. A local-first Mac editor driven by your own Claude Code or Codex over MCP.

At work

A few things I'm proud of

  • Performance

    Cut a key page's load time in half

    I led the move of an Angular approval workflow to React. Initial load dropped by 50%.

  • Reliability

    Added end-to-end tests to CI

    Set up Playwright tests that run in CI, so releases need less manual QA.

  • Scale

    Made pages about 70% lighter

    Rolled out Brotli and Gzip with the infra team, which lifted Lighthouse scores on our busiest pages.
