PROJECT ARBITRATOR // EDGE TELEMETRY NODE 2026 – PRESENT

Engineered a standalone 1090 MHz Mode-S/ADS-B edge station on a Raspberry Pi 5. Implemented low-latency RAM-disk demodulation, hardware thermal management routines, and an interactive FastAPI-powered tactical radar HUD.

SUBJUGATOR COMPUTE NODE // DISTRIBUTED SIMULATION ACTIVE

High-throughput distributed compute node configured for numerical simulation pipelines, aerostructural modeling, and automated data processing over encrypted Tailscale interconnects.
