I get spacecraft to the ground in one piece. Two lunar landers, forty-eight meters of landing accuracy, and a career that started on a machine shop floor.

I started on a Tucson machine shop floor in 2004, cutting flight hardware for instrument primes I would later design for. Nights went to a community college machining certificate, then an aerospace degree at the University of Arizona. I spent ten years at Verde Instruments, first testing hardware and then flying the guidance software on deep-space platforms. Since 2021 I have been chief engineer for lunar landing systems at Ocotillo Space Systems, where I own everything between the last engine burn and the moment the legs take the weight. I still teach the Tuesday night machining class I once sat in.

Two lunar missions manifested.
OBS 002
Guidance
Rebuilt the terminal guidance loop and the campaign that proves it, against the real flight computer and the real sensor suite.
210 m to 48 m landing dispersion.
OBS 003
Test
Built the lab that flies the vehicle's own avionics against synthesized terrain, sensors and faults before anything leaves the ground.
Four full descent campaigns.
OBS 004
Navigation
Navigation filter fusing star-tracker and inertial data for deep-space instrument platforms at Verde Instruments.
Still flying on an asteroid-survey platform.
OBS 005
Teaching
Evening course at Sonoran Basin Community College for machinists moving into instrumentation, test and flight work.

By the time the vehicle is falling, every decision it can make has already been made by people on the ground. What you fly is the argument you rehearsed. The campaign is the product.
The people who can already make a thing are the hardest half of the hire. What they usually lack is one person telling them the ceiling they were shown is not the ceiling.
