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.
