SELECTED WORK

Systems I’ve built.

At First Due, I lead customer data migrations through validation, UAT, and cutover. My independent work starts with RF and sensor data. More about my work →

WEATHER SATELLITE / RF

A ground station on my roof

I built a Raspberry Pi station that predicts METEOR passes, records the configured 137.9 MHz LRPT downlink, runs SatDump, and archives the decoded imagery.

4 decoded passes · 48 image products · as of 16 September 2026

AIRCRAFT / RF

My aircraft receiver and archive

I recorded 1090 MHz broadcasts, saved aircraft positions in PostGIS, and use the archive to inspect range, altitude, and traffic over time.

1.1M+ received messages · 60K positions shown · 131.92 km measured peak

BIOACOUSTICS / SENSOR DATA

Seven nights of ultrasonic audio

I recorded a Denver backyard at 250 kHz, screened 34 GB of audio with BatDetect2 and Kaleidoscope Pro, and checked the classifier results against the clips.
