If your Chrome Extension got rejected by the Web Store, breaks on MV3,
or needs AI features that actually work - I've solved all of these,
and I ship my own extensions to prove it.
I'm one of the few developers who builds Chrome Extensions full-time and
ships my own products to the Web Store (Encrypted Clipboard - live, used by many, zero-knowledge architecture). That means I've dealt with every
Content Security Policy rejection, every MV3 service worker limitation,
every manifest quirk - before your project, not during it.
What I specialize in:
→ Manifest V3 migration and new extension builds
→ AI integration inside extensions (OpenAI, Claude, Gemini, custom LLMs)
→ Chrome Web Store submission, rejection fixes, and compliance
→ Cross-browser support (Chrome, Edge, Firefox)
→ Backend APIs for extension data (Go, Node.js, NestJS)
