About this gig

Need a Chrome extension built, or an old one that stopped working after Manifest V2 was retired?

I build browser extensions in JavaScript on Manifest V3, tested in the browser and packaged ready for the Chrome Web Store.

WHAT I BUILD

  • Custom Chrome, Edge and Firefox extensions from your idea
  • Manifest V2 to V3 migrations for extensions that broke
  • Popup, side panel and content-script interfaces
  • Web automation: click, fill, extract and export page data
  • API and AI integrations (OpenAI, Gemini) inside the extension
  • Chrome Web Store packaging, icons and listing assets

HOW IT WORKS

  1. Tell me what the extension should do and which sites it runs on
  2. I confirm scope, permissions and stack before starting
  3. You get a loadable build to test as work lands
  4. Final delivery: source code, packaged zip and a store checklist

Extensions get rejected for permission and privacy mistakes. I build to the current store rules so yours does not.

Not sure what is possible in a browser? Message me first and I will tell you honestly.

Software engineer, 2 years building production systems, MSc in Computer Science. I build SaaS MVPs and full stack web apps in JavaScript - Next.js, React, Node and PostgreSQL - deployed live on your own hosting. Half-built products stall in the same four places: auth, database design, payments and deployment. I handle those properly, then hand you the source code in your own GitHub so you are never locked to one developer or platform. I also rescue apps started in Lovable, Bolt or Cursor. Message me with your feature list and I'll tell you what fits your budget and timeline.
