About this Gig
Chrome extensions are one of the fastest ways to add real value to your users' workflow but only if they're built right.
Manifest V3 changed the rules, and a lot of developers haven't caught up.
I build custom Chrome extensions on the current MV3 standard: secure, store-ready, and built to last. Whether you need a productivity tool, a browser automation layer, a scraper, or a SaaS feature delivered right in the browser I've built it.
What you get:
+ Fully Manifest V3-compliant extension no deprecation surprises
+ Clean, well-documented code you can maintain and build on
+ Chrome Web Store submission support (including policy review)
+ Integrations with any external API or your existing product
Got an idea for a browser tool that would make your users' lives easier? Let's build it.
FAQ
Why does Manifest V3 matter?
Google is phasing out MV2. Extensions built on MV2 will stop working. I build exclusively on MV3 — your extension is future-proof from day one.
Can it connect to external services?
Yes. REST APIs, GraphQL, WebSockets, OAuth — I integrate with any service. Built error handling, retry logic, and rate limiting included.
Do you build for Firefox and Edge too?
Yes. I can build cross-browser using WebExtension APIs. Same codebase adapted for Chrome, Firefox, and Edge with their specific quirks handled.
Can the extension be monetized?
Absolutely. I can add Stripe billing, freemium gating, usage limits, and a license key system. Turn your extension into a real business.
