Leo Galleguillos

Thank you for visiting my website. I am a self-employed software engineer with over 20 years of experience developing and maintaining cloud applications. I currently reside in Austin, TX and am working full-time on expanding our main businesses across LATAM and APAC.

In my spare time I enjoy learning foreign languages, improving my chess skills, playing the piano, using numbers to play with mathematics, working out, and trying to humbly discover what life is all about.

Personal Projects

Outside of our businesses, I maintain a few personal projects.

Blog articles in progress.

  1. Using microdata for structured data is often preferential for vast datasets although Google recommends JSON-LD
  2. LoRA models further blur demarcations between reality and simulation thereby rekindling classic metaphysical debate
