I build browser extensions

I lead the browser extensions development team at AdGuard, where we build the AdGuard Browser Extension — an open-source ad blocker trusted by 30+ million users across Chrome, Firefox, Edge, and Opera — 16 million on Chrome alone.

Outside of work I ship my own extensions: small, focused tools that solve everyday problems — from tracking extension updates to experimenting with AI-powered ad blocking.
