Need a Chrome extension built, fixed, finished, or taken over from another developer? I specialize in Browser extensions — from validating an idea and building the first MVP to debugging existing code, integrating backends and APIs, publishing to the Chrome Web Store, and maintaining the extension after launch. I work with startups, SaaS companies, agencies, and internal teams that need more than a basic browser popup. I can help with: - Custom Chrome extension development - Manifest V3 development and migration - Existing extension takeover, debugging, and repair - Finishing incomplete or AI-generated extensions - Chrome Web Store publishing and rejection fixes - Extensions for SaaS products and existing web applications - Backend/API integrations - Authentication, OAuth, subscriptions, and Stripe - Extensions that interact with third-party and logged-in websites - Data extraction, autofill, browser workflows, and page interaction - React / TypeScript extension development - Chrome extension security and architecture - Cross-browser support for Edge, Firefox, and Safari - Performance optimization, testing, and ongoing maintenance Not sure whether your idea is technically possible? I can also start with a technical feasibility review before you commit to a full build. We can determine what Chrome can reliably do, what permissions are required, whether a backend or API is needed, where the technical risks are, and what the right MVP should include. Already have an extension? Send me the existing codebase or explain what's broken. I can review it and tell you whether it makes more sense to repair, complete, modernize, or rebuild it. My goal is not simply to make an extension that works in a developer environment. I build extensions that are designed to be reliable, maintainable, publishable, and ready for real users. If you have a Chrome extension idea or an existing extension that needs help, send me a message with: 1. What you want the extension to do 2. Which websites or systems it needs to work with 3. Whether you already have code/designs/backend APIs 4. Where the project is currently stuck I can then recommend the best next step.
