About this gig
I build Chrome and browser extensions that do exactly what you need, nothing bolted on. That can be a small tool that adds one button to a page, or a full extension with a settings panel, saved data, and a proper interface.
I've been building for the web for over 16 years, so I work with the browser instead of fighting it. Content scripts, background workers, storage, API calls, and the current Manifest V3 rules are all handled, so your extension passes the Web Store review the first time.
A few things I've built before: page scrapers and data grabbers, productivity tools, form fillers, buttons that talk to your own API, and internal tools for teams.
Send me a short note on what the extension should do and which sites it runs on. I'll confirm the right package and a realistic timeline before you order. Want it live on the Chrome Web Store? I'll handle the submission and the listing too.
Firefox and Edge versions are available on request, since they share most of the same code.

I'm Gunjan (GJ), a full-stack developer with 16 years building for the web. I work in WordPress, WooCommerce and Shopify, and a lot of my work now is AI: chatbots trained on your content, AI agents, and automations that remove repetitive tasks. Expect clean, update-safe code, fast sites that work on mobile, and fixes that don't break other things. Whether you need a custom plugin, a Shopify store, a site rescued from errors, or AI built into what you already have, tell me what you're trying to do and I'll give you the honest, simplest way to get there.

FAQ
Will it get approved by the Chrome Web Store?
Yes, I build to the current Manifest V3 rules the store checks for.
Do you publish it to the store for me?
Publishing is an add-on. You'll need a developer account, which is a one-time $5 fee from Google.
Can it work on Firefox and Edge too?
Chrome and Edge share a base, so that's easy. Firefox is a small add-on since it needs a few tweaks.
Do I own the code?
Yes, fully. The code is yours to keep.
