Huzayfah Ameen
About this gig
Chrome extension broken? Rejected by the Chrome Web Store? Stuck on Manifest V2?
I fix extensions I did not build. Fast diagnosis, clean fix, no rewrite unless it is genuinely needed.
WHAT I FIX
- Manifest V2 to Manifest V3 migration (full service worker rewrite)
- Chrome Web Store rejections and policy violations
- Extension stopped working after a Chrome update
- Broken content scripts, popups and background logic
- CORS, permissions and CSP errors
- API calls failing, storage and messaging bugs
- Performance issues and memory leaks
WHAT YOU GET
- Root-cause explanation in plain language
- Fixed, tested, commented source code
- Verified on Chrome, Edge and Brave
- Resubmission guidance if you were rejected
- Short written summary of every change made
HOW IT WORKS
1. Send your source code (ZIP or repo) and the error or rejection notice
2. I diagnose and quote a fixed price and timeline before you order
3. I fix, test, and send you a working build
4. You confirm, I deliver final code and notes
Send me your code and the exact error before ordering. I will tell you honestly whether it is a quick fix or a rebuild, and quote accordingly.

Languages

Chrome extension developer. I build Manifest V3 extensions that connect to real APIs and automate real workflows.
5 years in JavaScript development. I work with SaaS teams, agencies and founders who need a working product, not a prototype.
What I do:
- API-connected extensions (REST, Firebase, Supabase)
- Workflow automation, scraping and data capture tools
- Manifest V2 to V3 migration and store-rejection fixes
- OAuth, auth flows and dashboard overlays
Clean commented code, 100% ownership, NDA on request. Message me with your idea and I will send back a written spec before you order.
My Portfolio
FAQ
Q1: I have a SaaS product. Can you build an extension for it?
Yes. I specialize in connecting browser extensions to existing web platforms. Share your API documentation and I will build a companion extension.
Q2: Will the extension work with my existing user login system?
Yes. I can integrate OAuth, JWT, or session-based authentication so your users do not need to log in again.
Q3: Can the extension fetch real-time data from my database?
Yes. I connect extensions to Firebase, Supabase, MongoDB, PostgreSQL, or any REST/GraphQL API.
Q4: Do I need to give you access to my backend code?
No. I only need your API documentation, endpoints, and authentication method. Your backend code stays private.
Q5: Will my users be able to install it from the Chrome Web Store?
Yes. I build store-compliant extensions and can handle the entire publishing process in the Premium package.
Q6: Can you build an extension that modifies other websites?
Yes. Content scripts can inject your UI into specific websites or all pages, depending on your use case and compliance requirements.
Q7: What if my website is built on WordPress, Shopify, or React?
The extension connects via API, so your website stack does not matter. I have worked with all major platforms.
Q8: Do you offer ongoing maintenance after delivery?
Yes. I offer monthly maintenance retainers for updates, bug fixes, and feature additions after the initial build.
