About this gig

I build custom Chrome extensions that save time and add useful features to websites. Explain the result you want in plain language. No technical brief is required. You receive a working extension tested on the latest Chrome version, full source code, a simple installation guide, and revisions based on your package. I built Chainless Maps, a complete Chrome extension with a settings panel, seven languages, and a server-verified license system. It is currently in Chrome Web Store review. My process is simple: I confirm the scope, price, and deadline, then I build, test, and deliver the extension. Please message me before ordering if your project uses an external API, a third-party website, or Chrome Web Store publication. I do not build social-media bots, security bypasses, or tools that collect private personal data. The service is provided by a minor under an account owned by the parents of Mael and managed by them.
