Alejandro Sierra, Systems Engineer

I'm Alejandro, a systems engineer working on AI and the infrastructure under it: agent runtimes, control planes, sandboxes, and the data paths in between.

This is where I keep my own projects and write things down.

Work since April 2026

  1. Cordatabuilding
  2. timeless-corebuilding
  3. Decibelrunning

Each line runs from first commit to today.

I take on a few outside projects a year, chosen by whether the problem matters more than by its size. If you have one, write to hello@sierralab.net.
