I'm a commercial HVAC technician finishing a BS in Cybersecurity Technology, open to opportunities in OT/ICS security, systems administration, and defensive security. Coming from trade work and emergency services, I tend to think in terms of reliability, failure modes, and systems that have to work under real-world conditions.

• OT/ICS security concepts, protocols (Modbus, BACnet), and lab environments
• Network security monitoring with Suricata and Zeek
• Python tooling for PCAP analysis and protocol parsing
• Preparing for a multi-semester digital forensics track -- disk, memory, and network forensics

otparse-mcp A containerized MCP server that parses Modbus/TCP and BACnet/IP packet captures using tshark and returns structured JSON for LLM-assisted analysis. Built to support OT/ICS traffic triage workflows.

Focus: OT/ICS protocols, packet analysis, MCP tooling, Python

netparse A general-purpose PCAP forensics MCP server, complementing otparse-mcp's OT/ICS focus with broader network traffic analysis for LLM-assisted triage.

Focus: Network forensics, PCAP analysis, MCP tooling, Python

mcp-test-env Containerized attack simulation lab with a red team node and sensor stack, used to generate and validate traffic for otparse-mcp and netparse development.

Focus: Docker, attack simulation, detection tuning

ot-hvac-testbed Microcontroller-driven HVAC control and instrumentation testbed exploring real-world OT concepts -- sensor telemetry, actuator control, serial data logging, and control logic across multiple platforms.

Focus: OT/ICS fundamentals, embedded systems, Linux-based data logging, system reliability

Linux (Ubuntu, Rocky) • Docker/Compose • Python • Bash • Git • tshark/pyshark • Suricata • Zeek • Modbus/TCP • BACnet/IP • TCP/IP networking • systemd

BS Cybersecurity Technology, UMGC (CAE-CD designated institution) -- in progress. Prior background in commercial HVAC, firefighting, and EMS. Home lab spans virtual and physical infrastructure -- dedicated NSM sensor and red team nodes, ESP32 wireless telemetry over MQTT, and Docker/Vagrant environments (currently being rebuilt post-migration) for networking and security practice.

Repositories here are intentionally documented to reflect operational thinking -- small systems that recover cleanly from failure and are easy to hand off.
