About Me

Hello. My name is John Bumgardner. I am a software engineer at Cisco Systems and an avid open-source software developer. I am originally from Stanfield, North Carolina, a small rural agricultural community in the South Piedmont region of the state, but I now live in Raleigh, North Carolina.


For as long as I can remember, I have been interested in technology. Growing up, I raced go-carts and dirt bikes with my dad, which piqued my initial interest in engineering. Later, however, my interests shifted away from mechanical systems and more to computer systems. In high school, I came across a textbook on C++ on a bookshelf in my house, and I soon (albeit with poor memory management) learned how to compose basic computer programs.


After graduating high school as a salutatorian, I attended North Carolina State University, where I double-majored in Electrical Engineering and Computer Engineering. I was elected chair of the university's Institute of Electrical and Electronics Engineers student branch. As chair, I led the organization's push to establish a student-led scholarship for electrical and computer engineering students. While at NC State, I participated in my department's accelerated bachelors masters degree programming, allowing me to complete graduate coursework alongside my undergraduate studies. I graduated in May 2021, earning my two bachelor's degrees summa cum laude.


Because of the transferability of the graduate coursework I had already completed, I continued my academic studies at North Carolina State University, pursuing a Master's degree in Computer Engineering. I took coursework in many areas, but my core focus was on software development and computer networking. As a graduate student, I served as a teaching assistant for a course on Object-Oriented Design.


Throughout my academic career, I partook in many internships and research opportunities. I worked for Cree Lighting on their Intelligent Lighting team as a hardware engineer intern, the SAS Institute on their production security team as a Technical Intern, Amazon on an emerging unreleased project in their entertainment space as a Software Development Engineering Intern, and as a programmer for many research groups within the Engineering Department at NC State. These experiences helped me hone my technical skills and prepared me to join the workforce.


In my free time, I am still involved in computing. I manage an open-source learning management system centered around peer learning. I started working on the project during my senior year of college. Initially exposed to it during coursework, I continue to manage the project today. Aside from programming, I am an avid history buff, specifically regarding the history of North Carolina. I also enjoy exploring the state, sometimes even on my bike through the state's greenway system.
