SaaS companies building in-browser AI sales assistants, CRM enrichers, clinical EHR overlays, and workflow automation tools frequently search to hire a freelance Chrome Extension (Manifest V3) & Side Panel AI copilot programmer. I am Aldian Fazrihady, a Senior Freelance Full Stack Developer and AI Application Engineer available via Upwork.

Core Chrome Extension Manifest V3 & Browser AI Capabilities

  • Manifest V3 Architecture (Plasmo / WXT / Vite + React): Building ephemeral Service Workers, isolated Shadow DOM Content Scripts that never clash with host page CSS (`Gmail`, `LinkedIn`, `Salesforce`, `HubSpot`), and persistent `chrome.sidePanel` AI copilot UIs.
  • Secure OAuth2 (`chrome.identity`), Offscreen Documents & DeclarativeNetRequest: Handling token refresh, audio capture via Offscreen APIs, and strict least-privilege permission scopes.
  • Fast Chrome Web Store Review Approval: Writing compliant privacy disclosures, single-purpose justifications, and remote-code-free bundles that pass Chrome Web Store review without rejection.

Frequently Asked Questions

Can you migrate our deprecated Manifest V2 Chrome extension to Manifest V3?

Yes. I refactor persistent background pages into event-driven MV3 Service Workers using `chrome.storage.session`, `chrome.alarms`, and Offscreen Documents while replacing blocking `webRequest` rules with `declarativeNetRequest`.
