I will build a browser extension for chrome
Ramshankar C
About this gig
Need a custom browser extension that actually works in production?
I'm a Senior Software Engineer with 8+ years of experience in JavaScript and Node.js, and I currently own a browser extension product end-to-end for a healthcare technology company from the extension itself to the backend that processes its data.
What I can build for you:
Chrome, Firefox, and Edge extensions (Manifest V3 compliant)
Popup UIs, content scripts, and background/service workers
Data collection, scraping, and DOM manipulation
API integrations and backend data processing (Node.js)
Companion admin dashboards to manage your extension's data
Bug fixes and Manifest V2 V3 migrations
Why work with me:
Unlike most freelancers who only build the extension, I can deliver the entire pipeline extension, backend, and admin portal because that's exactly what I do in my day job. Clean, maintainable code with proper error handling and observability baked in.
Let's discuss your idea message me before ordering if you have a custom requirement not covered by the packages above!

FAQ
Which browsers do you support?
I build for Chrome, Edge, and Brave (Chromium-based) as standard. Firefox support is available on request — just message me before ordering to confirm compatibility for your specific extension.
Do you follow Manifest V3?
Yes, all extensions are built to Manifest V3 standards. If you have an existing Manifest V2 extension that needs migrating, message me first so I can scope that separately.
Will I own the source code?
Yes, full source code is included with every package, and ownership transfers to you upon final delivery and payment.
Can you also build the backend/API my extension needs?
Absolutely — this is actually one of my core strengths. I can build a complete Node.js backend to handle data your extension collects, plus an admin dashboard to manage it (included in the Premium package).
What if my requirements don't fit the packages listed?
No problem — message me with your requirements before ordering and I'll either recommend the right package or send a custom offer tailored to your project.
