intention.

I’m John Sandoval. I turn complex problems into thoughtful software, connecting architecture, AI, and the people who use it.

A workspace for running Claude Code and Codex across repositories, from the first prompt to pull request follow-up. Built in Rust, guided by architecture and product thinking.

The story behind the build? I didn’t know Rust when I started.

AI & architecture

The language is no longer the ceiling.

I built Fleet in Rust without knowing Rust. It changed how I think about the work of building software.

03 / A little context

People first.
Systems second.

I care about how things fit together.
And who they’re built for.

My path has taken me from IT and customer support to engineering and solutions architecture. That perspective stays with me: a system only works if it works for the people using it.

Today, I’m a Solutions Architect at Extend. Previously, I worked in AI engineering and solutions at Xurrent and UserTesting. I’m interested in AI agents, automation, and making complex systems easier to work with.

This is where I share what I’m building, the decisions behind it, and the things I’m still figuring out.
