Systems Architect โข SIGINT-Inspired Geospatial & Wireless Intelligence Systems
I design and maintain the ShadowCheck Geospatial Signal Intelligence Platform. My work focuses on the intersection of wireless RF analysis, forensic-grade data processing, and hardened AWS infrastructure. I prioritize system reproducibility, data integrity, and modular architecture over monolithic design.
ShadowCheck is not a collection of isolated projects; it is a unified, layered system designed with strict unidirectional data flow. It ensures forensic-grade data integrity from field capture through to analytical visualization.
- WiGLE: External bootstrap dataset utilized strictly for cold-start validation, not a system dependency.
- ShadowCheckMobile: First-party Android RF collection system designed for sovereign, high-fidelity signal capture.
- dbcoopers-briefcase: AWS S3-based infrastructure pipeline handling the staging, validation, and secure transport of raw field telemetry into processing environments.
- ShadowCheck Core Engine: The primary analytical engine responsible for signal ingestion, enrichment, emitter classification (differentiating transient vs. persistent), and geospatial normalization into PostGIS.
- ShadowCheckWeb: The primary operational control plane. A React and Mapbox-driven interface providing real-time and historical geospatial intelligence visualization.
- Structure first, then scale: Prevent technical debt through rigorous architectural foundations.
- Modularity over monoliths: Distributed, decoupled, and observable components.
- Forensic mindset: Data is evidence; ensure it is traceable and untampered.
- Signal over noise: Aggressive filtering to surface high-value intelligence.
- Automation with intent: Purpose-driven orchestration of system lifecycles.

"Build systems that explain themselves. Trust data you can trace. Eliminate noise until only signal remains."
