Agustin Barrientos

I'm a frontend engineer and UI/UX designer with more than 15 years building for the web. I'm originally from Argentina, and these days I'm living abroad.

I work at Uncanny Owl, where I build the frontend of Uncanny Automator, a no-code automation tool, and Uncanny Agent, its AI copilot. Both are built entirely with Lit, on top of an in-house library of reusable components and reactive controllers I created myself, which is what lets the Agent run independently of whatever it plugs into. Now and then I speak on the importance of UI/UX, sharing practical ways to improve your users' experience and convert better.

I also write. The Senior Eye is about how a senior decides. We build something real together, a working Lit component, and reason through the trade-offs behind it, when a freshly shipped feature is worth adopting, what the browser should handle for you, what still earns hand-written code, and when a clever trick turns into a trap. The Brief is the short one, a weekly roundup of the frontend and AI-in-frontend news that's actually worth your time.
