I will build or fix chrome extensions with API integration and automation
Junes
Level 2
About this gig
Need a Chrome extension that automates work, connects to an API, or fixes an existing tool?
I build reliable Manifest V3 Chrome extensions for business workflows, browser automation, data handling and API-connected features.
I can help with:
- New Chrome extension development
- Fixing or extending existing extensions
- Manifest V3 updates and migrations
- API, webhook and OAuth integrations
- Browser automation and form filling
- Data extraction and page interaction
- CRM, SaaS and internal-tool integrations
- AI features using OpenAI, Claude or Gemini
- Authentication, storage and settings
- Background service workers and content scripts
- Chrome Web Store submission support
I focus on clean, maintainable code and real-world reliability, not just a demo that works once.
If your extension needs a backend, database or custom Python service, I can build that too.
For complex projects, please message me before ordering so I can confirm scope and recommend the right package.

FAQ
1. Do you build Chrome extensions with Manifest V3?
Yes. New extensions are built around current Chrome extension standards and Manifest V3 unless a project has a specific technical reason requiring something different.
2. Can you fix an extension built by another developer?
Yes. I can take over existing extensions, diagnose bugs, repair broken functionality, update APIs, add features and modernize older code when the source code is available.
3. Can you integrate APIs into my Chrome extension?
Yes. I can integrate REST APIs, webhooks, OAuth, SaaS platforms, CRMs and custom backend services. For complex integrations, send me the API documentation before ordering.
4. Can you add AI features?
Yes. I can integrate OpenAI, Claude, Gemini or other model APIs for features such as summarization, extraction, classification, content processing or workflow automation.
5. Can the extension work with Firefox or Edge?
Yes. Edge compatibility is often straightforward and Firefox can also be supported, but browser-specific differences may require additional development and testing.
6. Can you publish it to the Chrome Web Store?
Yes. I can prepare and submit the extension through your developer account. Store approval is controlled by Google and cannot be guaranteed or included in my delivery-time promise.
7. Can the extension scrape or extract website data?
Yes, where the requested data and workflow are technically appropriate and you are authorized to access it. I can structure extracted data and send it to APIs, files or business systems.
8. What do you need before I order?
Send me the desired functionality, target website or workflow, any existing source code, and API documentation if integrations are involved. For complex projects, message me first.
