About this gig

Need a Chrome extension that does one job properly? I build custom extensions for businesses and for your own workflow.


WHAT I BUILD

Extensions that scrape or collect data from pages you visit

Tools that add buttons and panels to sites you already use

Form fillers and repetitive task automation

Extensions that talk to your own API or a spreadsheet

Internal tools for your team rather than the public store


WHAT YOU GET

The complete source code, yours to keep

Built on Manifest V3, the current Chrome standard

A short guide to loading and updating it

Help preparing the Chrome Web Store listing on the Advanced package


Tell me what you want the extension to do and which sites it runs on, and I will tell you what is realistic before you order.

I help website owners find and fix the accessibility barriers that lock disabled users out of their site and create legal exposure under the ADA, the European Accessibility Act and Section 508. Every audit pairs automated WCAG 2.1 AA testing across your full site with manual screen reader and keyboard-only verification, because automated tools alone catch barely half of real failures. You get a prioritised report: what is broken, who it blocks, the exact element at fault, and the fix. No overlay widgets, no plugins. Just real code-level findings you or your developer can act on.
