PUCK
active development

Self-contained sensor node for long-duration field deployment — 2 to 5 years unattended. Runs edge ML inference for continuous multi-modal fusion, classifying radar and acoustic signatures in real time and relaying detections over LoRa. Units will eventually form a self-healing mesh, sharing tracks autonomously.

concept · early development

Loitering expendable interceptor cued by the PUCK mesh. Inherits track data from the network, navigates autonomously without GPS, and closes via onboard radar and sensor fusion. Deploys a Kevlar net against Group 1–3 sUAS. Concept stage — shared compute architecture with PUCK.

I'm a CE student at University of Denver and I work in avionics. Most of my time goes into embedded systems, sensor interfaces, and low-level firmware.

Shields Systems started because I wanted to build something that mattered. The drone threat problem is real, the existing solutions are either too expensive or too complex to deploy at scale, and the underlying hardware to do it cheaply exists now. So I'm building it.

PUCK is the starting point, a field node that fuses radar and acoustic data at the edge, runs for years on a charge, and talks to other nodes over LoRa. HARPY comes after, once the sensing layer is solid. The idea is an interceptor that the mesh network itself can cue and guide — no pilot, no uplink during the intercept.

Early days. This is a nights-and-weekends project right now.
