I will develop a custom chrome extension or browser extension
Hassan Saeed
About this gig
Need a Chrome extension that saves your team time, adds a feature to a website you use every day, or turns your idea into a product? I build fast, secure extensions with clean code.
I'm Hassan, a full stack developer with 12+ years of experience. I've built and published my own extensions, including PixGrab, CapturePDF, ApplyFlowAI, FocusPulse AI and Toolscase PDF Tools, so I know Manifest V3 and the Chrome Web Store review process inside out.
What I can build:
- Productivity tools, popups and side panels
- Page modifiers: add buttons, hide elements, auto-fill forms
- Screenshot, PDF and content capture tools
- AI-powered extensions (ChatGPT / Claude)
- Extensions connected to your own API, CRM or backend
- Login, license keys and paid subscriptions
You get:
- Manifest V3, Web Store ready
- Full source code and setup guide
- Help with publishing and store review
Message me your idea and I'll reply with a quick plan and the right package.

I help with bug fixes, AI chatbots and ChatGPT/Claude integrations, Chrome extensions, Stripe payments, APIs and deploying apps to AWS.

FAQ
Will my extension pass the Chrome Web Store review?
I build to Manifest V3 and Google policies from day one and handle the store listing, privacy fields and permissions, so your extension has the best chance of fast approval.
Can you also make it work on Firefox and Edge?
Yes. Edge runs Chrome extensions natively, and I can port and publish a Firefox version too. It is available as a gig extra.
Can you fix or update my existing extension?
Yes. I can fix bugs, add features, or migrate an old Manifest V2 extension to Manifest V3 so it keeps working in Chrome.
Will I own the code?
Yes. You get the full source code and own it completely. I also include a short guide so you or another developer can maintain it.
