Background
Professor of Computer Science
& Lecturer in Computer Engineering
U.S. Navy Veteran
Built a strong technical and leadership foundation through active-duty service as an Electrician's Mate in the U.S. Navy.
BS (Summa Cum Laude)
Electrical Engineering
MS Systems Engineering
Combined Electrical Engineering and Systems Engineering training to understand both how systems are built and how they work together.
Professor & Engineer
Brings college teaching and real engineering experience together to help students connect code, hardware, and real-world systems.
What I Teach
Every Side of
Real Engineering
My teaching focuses on helping students understand how technology actually works, not just how to use it. Every Programming Journeys program is built around that idea, with each one introducing a different side of real engineering.

IoT & App Development
IoT connects hardware, sensors, software, and app-style interfaces into complete working systems.
Learn moreTogether, these programs help students see that software, hardware, AI, networking, and connected devices are not separate worlds. They are all part of the same engineering process.
Technical Experience
From Software to
Autonomous Systems
Joint Tactical Radio System
Worked on software-defined radio systems from 2009–2012, writing Python-based tools and supporting communications platforms built for complex engineering environments.
MQ-25 Stingray Program
Designed and developed network systems for unmanned aviation from 2012–2018, including LAN, VLAN, WAN, VPN, and beyond-line-of-sight communications.

Autonomous Surface Vessels
Leads Test & Evaluation efforts for autonomous Navy systems since 2018, managing engineers, mentoring interns, and supporting real-world unmanned vessel operations.
From 2009 to the present, the work has ranged from software-defined radios to carrier-based networks to autonomous surface vessels.
That progression from software to networking to autonomy is the same systems-level thinking that shapes how students learn in Programming Journeys.
