Indie developer · AI-powered Chrome extensions

I build AI-powered Chrome extensions that live in the side panel and do real work. Currently: Claude Animation Skills — 100 animation skills for Claude Code, turned into vertical videos with one command — and Hark AI Agent, a personal AI agent for Chrome that asks before it acts. I write about Manifest V3, browser agents, Claude Code and shipping small products.
