About this gig
Need a browser extension that actually does something useful?
I built a Chrome and Brave extension that rotates VPN connections across country lists, pairs each IP with randomised user-agent strings, and auto-detects 404 errors to trigger an IP switch all running silently in the background. Real extension, real logic, real users.
WHAT I BUILD:
- Popup UI with controls and settings
- Content scripts that interact with any webpage
- Background service workers for silent automation
- Chrome storage for saving user preferences
- API integration with external services
- Python backend if your extension needs a server
- Works on Chrome, Brave, and Edge
WHAT YOU GET:
- Full source code and manifest
- Tested and working in latest Chrome
- Documentation to install and modify it
- Chrome Web Store publishing guide (Premium)
Message me before ordering with a description of what you want the extension to do. I will confirm it is possible before you pay.

Full-stack developer with 4 years of production experience. I've built live deployed platforms — an LMS ranked 2nd on Google for 'Best Coaching in Karachi', a community management system handling real payments and memberships, and an automated healthcare data pipeline processing 10,000+ daily records from multiple APIs. I work with Next.js, TypeScript, Python, PostgreSQL, Power BI, and Node.js. I deliver clean, working, production-ready code — not throwaway scripts.

FAQ
What types of extensions can you build?
Productivity tools, automation extensions, web scrapers, UI injectors, API-connected tools, VPN or proxy controllers, ad blockers, custom dashboards — anything that runs in a browser. If you can describe it I can likely build it.
Will it work on browsers other than Chrome?
Basic covers Chrome only. Standard adds Brave. Premium covers Chrome, Brave, and Edge. Firefox uses a slightly different API — message me if you need Firefox support.
Can you submit it to the Chrome Web Store for me?
I provide a complete publishing guide with all required assets (icons, screenshots, store description) in Premium. The actual submission requires your Google developer account — I walk you through every step.
Can the extension connect to an external server or API?
Yes — Standard includes one API integration. Premium includes multiple integrations plus an optional Python backend if your extension needs server-side logic.
Will it still work after Chrome updates?
I build using Manifest V3 which is the current Chrome standard and will be supported long term. Older MV2 extensions are being phased out — I only build MV3.
