I build browser extensions for Chrome, Edge, Brave and Firefox on the current Manifest V3 standard, from small productivity tools to extensions that are a product on their own.

Tools that read or change pages: highlight, extract, fill in or clean up

Sidebars and popups that call your API or an AI model

Automation for repetitive work inside a web app your team uses

Extensions connected to your own SaaS account and login

Moving an old Manifest V2 extension to V3

I ask only for the permissions the extension needs, so the store review goes smoothly and users trust the install screen.

You get the full source code, a packaged ZIP ready to upload, and help with the store listing.

Everything happens in writing, no calls needed. Send the task, the deadline and the budget, and I reply the same day.
