WARREN TECH • 8-9-05 to 6-1-2024• 40 hours/week • Lakewood, CO

Secondary Teacher – Computer Science, Cybersecurity and Machine Learning

Warren Tech (WT) is a CTE option school in the Jeffco School district, the largest school district in Colorado with 86,000 in 155 schools. 

  • I have two classes: AM, 7:30 AM – 10:30 AM, and PM, noon – 3:45 PM. Students are brought to WT via 19 feeder high schools throughout the district, and some mountain communities. My program is a two-year program: Students can come in starting in their junior year. If a student is a senior, but this is their first year with me, I consider them a first-year student in terms of my class. Seniors who are starting their second year with me write a Senior Capstone Project Plan that they use to gather more training in the type of Information Technology (IT) subjects in which they are interested, and which prepares them for college and career. I usually have over 25 students in each of my classes.
  • I teach the CompTIA suite of IT Pro certifications (IT Fundamentals, A+, Network+, Linux+ and Security+). My class is a CompTIA Academic Alliance partner. I routinely attend the CompTIA Partner Summits each year.
  • I am also a member of Cisco Academy and offer my students several different Cisco Academy classes. For example, the US CyberPatriot competition in which many of my students participate has a Cisco Packet Tracer segment. I require students to go through the Packet Tracer Essentials class as a part of their coursework.
  • I also teach students Python programming, as well as web development using HTML, CSS, and JavaScript. Students have the option of going through Machine Learning (ML) training in my class, which earns them a second math credit.
  • The last five years I have been focused on artificial intelligence (AI), machine learning (ML), deep learning (DL), and data science (DS). I use a combination of books (e.g., Jake VanderPlas’ Python Data Science Handbook), Python programming, statistics training, and hardware such as the Nvidia Jetson Nano, and the AWS Deep Racer autonomous cars.
  • My best coders participate in an annual coding competition that happens in the spring and is hosted by Lockheed Martin. It is called CodeQuest. We have placed several of the years in which my students have participated in this competition.
  • Students that are deeply interested in cybersecurity have an opportunity to participate in the annual Lockheed Martin CyberQuest competition, which is essentially a red team/blue team kind of thing. We took first place in the 2023 competition in Colorado.
  • We participate in the US Air Force Association CyberPatriot competition on a regular basis. In previous years we have placed in the top 10% of teams.
  • In addition to students participating in various competitions such as Lockheed Martin’s CodeQuest and CyberQuest, and the US CyberPatriot competitions, students also compete in the annual Colorado School of Mines programming competition. In its inaugural year, my students took first place, and we took first place again in 2023.
  • Additionally, I teach a lot of cybersecurity-oriented content, including Kali Linux, and hacking electronics using HakShop’s Rubber Ducky, Bash Bunny, LAN Turtle, and WIFI Pineapple.
  • I have a strong articulation agreement with Red Rocks Community College (RRCC), which is just down the street from my school. I have been in the capacity of adjunct instructor there for the last 15 year. Students can earn up to 20 college credits because of this articulation agreement. Additionally, in the past RRCC has provided wonderful mentors who have been helpful to the students participating in the CyberPatriot competition.
  • I am a member of the Computer Science Teachers Association (CSTA) and have been actively involved with this organization for several years.
  • I enjoy teaching capture the flag (CTF) sessions. I am a member of Cyber.org, Hack the Box, and Try Hack Me.

XCEL ENERGY • 10-20-80 to 4-24-93 • Leadville, Silverthorne, and Denver, CO

Programmer, customer support technician, computer trainer

When I first started working at Xcel, I was a meter-reader in the Colorado Summit County area. I moved into the Silverthorne office, and finally moved from there into gas and electric (G&E) dispatch. In 1982 I transferred to Denver and worked seven years as an electric distribution dispatcher, responsible for the entire Denver metro area. I took tons of mainframe classes along with PC classes such as Ashton-Tate dBase III+, WordPerfect and Lotus. I transferred out of the dispatch center to work as a mainframe and PC programmer in the building in which the dispatch center was located. I ran Mark IV mainframe reports and created dBase databases. After two years there I transferred into the Data Processing (DP) training department and began teaching Lotus 123, WordPerfect, DOS batch file creation, dBase and other classes like that. Xcel decided to close the DP training department, so I transferred first to Human Resources where I was a programmer, and then to a department that handled mainframe assembler code. Finally, Xcel decided to outsource all their IT operations to IBM, and I made the decision to separate from the company at that juncture.
