About this gig

I do custom chrome extension development for the Chrome, Edge and Firefox stores - Manifest V3, done right across all three browsers, not just Chrome.


What I build:

  • Content scripts that read or change pages
  • Popup and options UI (React, Preact or vanilla)
  • Background service workers, storage, messaging
  • Context menus, keyboard shortcuts, downloads
  • Cross-browser builds (Chrome, Edge, Firefox) from one codebase, plus a userscript build if you want it


I have built and shipped multi-browser MV3 extensions from a single codebase - image-format converters, tab tools, page utilities. I know exactly where Firefox MV3 diverges from Chromium (background type, permissions, userScripts) and handle both branches so nothing silently breaks on one browser.


New build from scratch or chrome extension development on a codebase you already have - tell me what the extension should do and on which browsers, and I will scope it.

I build and ship full-stack web apps - Next.js, Nuxt, React, Vue on a Node/TypeScript backend, deployed to Vercel or Cloudflare. Around 6 years of commercial work: SaaS MVPs, dashboards, REST APIs, landing pages, and browser extensions. I scope tightly, ask the right questions before I start, and send you a live URL you can click, not screenshots. Real deployed work at selim.services. Tell me what you're building and I'll say honestly whether I'm the right fit.
