Operator. Builder. Technologist.

I run operations for a living, and I write the software that keeps them running.

Selected work

Here’s what I build.

All of it is in use today.

Firmware · ESP32‑S3 e-ink reader

TheotokOS

A Catholic companion for the Xteink X4 Pro, in English and Spanish. The day’s Mass in either Missal, a catechism lesson and a quiz, the saint of the day, and a liturgical calendar the reader works out for itself. The Rosary, chaplets, litanies, the Stations of the Cross and an examination of conscience. Mass times and 285 parishes. All of it offline, and updated over the air. Version 1.0, built around the Daily Mass, is next.

Interactive Rosary

The rosary is the interface: one button forward, one back, and the lit bead is where you are. All four mysteries, and the chaplets on the same beads, in English and Spanish.

Private security · California & UK

Security systems

Operations consulting for guard-services firms, and the systems behind it: billing engines that turn guard hours into client invoices across 19 sites, and the platform for a London guarding firm.

About

Bio

I’m originally from San Jerónimo Xonacahuacan, in Tecámac, Estado de México.

My parents and I came to the United States together, so I’m a first-generation immigrant, and we settled in Boyle Heights in 1992. I finished high school at Woodrow Wilson’s Police Academy Magnet in 2007, and that summer I went into the Marine Corps.

I trained as a technical engineer at Fort Leonard Wood, Missouri, and served with 9th Engineer Support Battalion in Okinawa. Then I went to Quantico as building manager for Marine Corps Combat Development Command. That’s where I became a citizen. On September 20, 2010, I was naturalized at the Smithsonian National Museum of American History in Washington, D.C., and led the new citizens in the Pledge of Allegiance. AFP photographed the moment. Shortly after, I reenlisted for a second term.

For that second term I made a lateral move to machinist and finished the machinist course at the U.S. Army Ordnance School at Fort Lee, Virginia, as honor graduate. Then I joined the Precision Weapons Section at Quantico, a shop with no equal in the Department of Defense. Its Marine armorers and civilian machinists repair, maintain and improve weapon parts and designs, and hand-build match-grade sniper rifles and competition pistols for the Marine Corps Shooting Team.

My main job there was producing M40A5 sniper barrels, threaded to high tolerances from the manufacturer’s raw stock. I also taught in the gunsmithing school for armorers and was named Instructor of the Quarter for the third quarter of 2012. That same year I did the research and development on custom recoil-reducing gas compensators for the Combat Match Team’s rifles.

I finished my eight years as Machine Shop Chief for 1st Light Armored Reconnaissance Battalion. I learned to read a blueprint and hold a tolerance twice, first at Fort Leonard Wood and again at Fort Lee, and at PWS I learned how to teach both.

I got out in 2015 and went to work for Scoobeez, a delivery company in Pasadena. We launched Eat24, Thistle and Hopsy in San Francisco and Amazon Prime Now’s one- and two-hour delivery in Santa Monica. I ended up running 13 hubs across California, Texas, Michigan and Nevada before we moved into Amazon’s delivery partner program.

In 2019 I went out on my own. MoonStone PEO was my first client, and I’m still there as VP of Operations. I also consult for security companies here and in the UK and for a few employer-services firms, and I build web portals for businesses, parishes and nonprofits.

Since 2020 I’ve been the majority shareholder in Aurum Ortus, a gold and silver mine and processing center in Tototlán de Oro, Jalisco.

Most of the software on this site started as something I needed at work. TheotokOS and the rosary app are the exception. Those are for my faith.

Away from work I shoot film and print in the darkroom. I shoot everything from 16mm up to 6×14, plus 4×5 large format. Instant film is my favorite.

I’m married, and we have two kids.
