JES2 Development Intern, IBM, June 2020 to December 2020

JES2 is a component of z/OS, an enterprise mainframe operating system developed by IBM. JES2’s functionality within z/OS is to act as a core manager for batch jobs executed on the system, and as such, working with JES2 requires an all-encompassing understanding of the mainframe ecosystem. This internship allowed me to work with mainframes and many of their associated technologies, such as z/OS, z/VM, and ISPF. It also allowed me to work with several IBM languages, those being HLASM, JCL, and others internal to IBM. I had no experience with the style of computing that mainframes require before this internship, so it has been a wonderful opportunity to be given a solid familiarity with the system.

  • Gained experience and familiarity with the mainframe ecosystem
  • Worked with many different technologies including HLASM, Z/VM, Z/OS, and ISPF

Gradute Assistant, North Dakota State University, August 2021 - Present

As a cybersecurity focused graduate assistant I am currently working with several other graduate students on developing a distributed, novel attack system. Due to the nature of the project I am not allowed to discuss details of what system it currently targets or in what respects it is novel. The system is being developed in C++ with elements also implemented in Lua, and because of its distributed nature we are also working with build systems on both Linux and Windows.

Cybersecurity Research Experience for Undergraduates, North Dakota State University, June 2019 - August 2019

The Research Experience for Undergraduates is a program sponsored by the National Science Foundation to encourage research to be conducted by undergraduate students in a growing number of different fields. I participated in the NDSU hosted Cybersecurity REU and developed, conducted, and wrote about the use of machine learning in post attack forensic analysis. My project was specifically about the use of unsupervised learning on profiling users by Bash history. My paper Use of Bash History Novelty Detection for Identification of Similar Source Attack Generation was published at the 19th IEEE International Conference on Trust, Security and Privacy in Computing and Communications (IEEE TrustCom 2020) at the end of December 2020.


Cyber Skyline’s NCL Regular Season Fall 2021 CTF Competition, Placed 10th of 6400+ players

A Capture the Flag competition is a competition in where players are given a wide array of hacking challenges with the goal of having players use many different cybersecurity skills to solve problems to get an end “flag.” An example of a basic challenge would be to use an SQLI vulnerability to leak a database that holds a specific string that is the final flag. Cyber Skyline’s NCL CTF competition consisted of categories including cryptography, reverse engineering, log analysis, password cracking, web application exploitation, and several others. In the individual section of the competition, I placed 10th out of 6,475 players nationwide.

2019 National Cyber Summit Cyber Cup Challenge, Placed 2nd out of 10+ college teams

The National Cyber Summit Cyber Cup Challenge is a team-based CTF taking place live during the Annual National Cyber Summit conference. I was the team captain of a team consisting of 4 members. We worked as a team to solve cybersecurity problems in several different categories, with a strong focus on web application exploitation.

Digi-Key Collegiate Computing Competition 2021, Placed 3rd out of 15 college teams

Digi-Key’s Collegiate Computing Competition (DKC^3) is a programming competition that consists of three main events: short programming problems, long programming problems, and word problems. Each segment of the competition is time-constrained and as such teams must strategize which problems to pour resources into and which ones to ignore. The 2021 competition was my second time participating and our team placed 3rd out of the 15 college teams that were in attendance.


National Collegiate Cyber Defense Competition, Particiated 2019 and 2020

The National Collegiate Cyber Defense Competition (CCDC) is a college level cyber defense competition in which teams are given a mock business infrastructure purposely built with a large number of security vulnerabilities. These vulnerabilities must be found and fixed while a team of penetration testers attempts to breach the network and leak information. Technologies change every year, but Active Directory and Linux servers appear frequently. I have participated in this competition as both a team member (2019) and a team captain (2020).

National Collegiate Penetration Testing Competition, Participated 2019 and 2020

The National Collegiate Penetration Testing Competition (CPTC) is a college-level cyber offense competition in which teams are presented a mock business infrastructure that they must perform a penetration test on and then create a report of findings. The competition enforces real-world penetration testing considerations, such as losing points for knocking services offline and receiving emails from a point of contact asking for test updates. The report filed at the end is entirely crafted by teams, without being given any sort of direction or template, requiring research into how penetration test reports are written in real-world penetration tests. I have participated as a team captain two years in a row, leading two different teams of 6 individuals each.


C++, 4 years experience (2017)

My primary development language is C++, I tend to use it largely with networking and hardware but have also used it with libraries such as OpenGL.
