Everything in this site are opinions, my opinions, and none of them represent those of my current or previous employers.

My name is Guillermo Sandoval, but you can call me Memo – short for Guillermo in Spanish. I'm a Software Engineer by day, professional bug writer by night. I'm passionate about most things software and love to tinker; attempt to fix what's not broken as a hobby, little bit of electronics, little bit of 3d printing, you get the picture.

I'm originally from Mexico, but have been living in the United States for quite some time now, time flies.

If you are looking to connect, email me to the letter m, at this domain - so that is the maker.gs but replacing the letter a with the @ symbol.

Educational background

I studied my bachelor's degree in the now National Technological Institute of Mexico. My bachelor degree is roughly equivalent to Computer Science. I used to argue that it was closer to Computer Engineering, but experts in the area seem to disagree, it's not important.

Some time after graduating I started the graduate program of Cybertronics at the La Salle university. I completed about 19 courses but never completed the degree. I'm at a point in my life where I understand myself as someone who loves learning, but doesn't like school that much.

Work experience

I work at Duolingo – started on 2025. I'm the lead for the responsible for Observability. This builds on the experience I gained for 7 years working at Google being responsible for systems supporting debug logging (collection, storage, and querying), log based insights and storage systems for monitoring metrics.

Before that I used to work for Critical Mix - a company in the market research field. I worked as a DevOps engineer for several years. It was an early Cloud computing adopting company. And before market research I spent some time in the financial, communications and the health care sectors.

In the past +15 years I have been fortunate to land in jobs that have always proven challenging and fun, but what I've always found the most rewarding has been the extremely unique people I've got to worked with. I'm extremely grateful with so many of my previous co-workers and friends; they have provided their own point of view, many times different from mine, and they've showed me a new way, a new inspiration.
