USAFA 2001
Space systems engineer and software architect with 20+ years across DoD, IC, and commercial space. Founded DigitalArsenal.io; built the Space Data Network, a decentralized protocol for standardized space data, and the first WebAssembly astrodynamics tools to run natively in the browser.
3D orbital visualization engine on CesiumJS — real-time satellites, sensor and viewshed modeling, conjunction analysis — and the SSA platform built on it, with AI globe control over MCP and a CCSDS-based REST API.
Decentralized peer-to-peer protocol for space data over libp2p — GossipSub, Kademlia DHT, content-addressed storage — with a trust-based data marketplace.
127 FlatBuffer schemas typing space operations: orbital elements, ephemeris, conjunctions, tracking, identity, and marketplace protocols.
First WebAssembly ports of TU Delft’s Tudat astrodynamics toolbox and the Basilisk spacecraft simulator — high-fidelity propagation and 310+ dynamics classes in the browser.
Browser port of Google’s FlatBuffers compiler (13 languages, ~250M ops/sec zero-copy reads) and a SQL layer over FlatBuffers data via SQLite virtual tables (~580K ops/sec).
WebAssembly HD wallet library — BIP-32/39/44 across 50+ networks with Ed25519, secp256k1, and secp256r1 signing, FIPS 140-3 compliant.
Leads the space systems portfolio: astrodynamics, space domain awareness, and mission software for DoD and IC customers.
Created OrbPro, a CesiumJS fork with in-browser WebAssembly astrodynamics, shader-based viewshed analysis, and sensor-coverage libraries. Architected SpaceDataStandards.org and the Space Data Network, winning a Department of Commerce schema contract. Multiple SDA TAP LAB cohorts, awarded for tap.spaceaware.io; built an NLP catalog-query pipeline and Orbit Viz for Celestrak.
Turion Space / Space Systems Command. Built the Space-Based Interceptor demo supporting Golden Dome award capture, briefed in person; set NEI capture requirements with NGA/SXOS. Supported Saber Astronautics web applications and AST Mobile telemetry on Kubernetes.
NGA / IC / DoD. Built the WIC Imagery Retrieval System feeding ~3 TB of daily imagery to Large Data OMAR; developed FP, a CesiumJS/Vue imagery–SIGINT fusion tool used operationally in 2016; delivered ELK geospatial analytics, an encrypted payload delivery system, and Lycan CPI.
Integration specialist at ADF-East: Coherent Change Detection tooling, an STK SAR-glint look-angle tool, a custom STK overflight tool for an Air Force space defense program, OGC web services in the SSA Software Suite, and STK-to-CesiumJS visualization.
DevOps lead and scrum master for Space-Track.org under JFCC SPACE/J3 — rebuilt the site around 90M+ records and 30,000+ accounts with REST services across SIPRNET and NIPRNET. Built conjunction tracking and CSM interfaces, designed the JSpOC knowledge management system, and edited the JFCC SPACE FOC CONOPS.
Chief of Ground Systems Engineering (2006–2007): owned ground procedure review including cryptographic key rollover; wrote the 50th Space Wing classified status reporting system.
ECHO Crew Commander (2006): led a 10-member crew managing 900+ satellite supports on $3.9B in space assets at 99.9% mission success. WGS Engineer / Chief of Procedures (2005–2006): first military Boeing WGS operator class; wrote 3,000+ lines of TAO scripts forming the constellation’s command and control suite.
Weapons and Tactics Officer (2003–2004): tactics for the $2.1B DSCS constellation; built 500+ HMI screens for the CCS-C ground system. Flight training (2001–2003): 230+ rotor and fixed-wing hours; instructed 500+ cadets at the USAF Academy.
