About

I'm Bruno Prieto, a blind software engineer based in Madrid. I build software, work on accessibility, and make tools that solve problems I run into. I also help teams improve their products, often by making the fixes directly in their codebases.

I've helped improve the accessibility of Basecamp 5 and Hello Weather. I authored the Rails Accessibility Guide for the Rails Foundation, spoke at Rails World 2024 about making accessible web apps with Rails and Hotwire, and previously worked at 37signals. I'm a Hotwire contributor and the author of the open source Focus Trap package.

I co-founded Callback Systems, where my partner and I build Mentables, a software product that has evolved from an earlier scheduling tool into an agent-focused project. I also enjoy experimenting with developer tools, assistive technology, and other software I wish existed.

I've been building web apps for as long as I can remember, starting around age eleven with a free .tk domain, a Dropbox public folder, and absolutely no idea what I was doing. The full version of that story is on the blog.

Off the keyboard I play drums, usually along to Iron Maiden.
