I am a Linux and containerization enthusiast with a strong focus on Red Hat Enterprise Linux, Kubernetes, and OpenShift. My passion lies in automating complex infrastructure and enabling scalable, reliable application delivery through modern DevOps practices. Over the years, I’ve developed deep expertise in system administration, container orchestration, and CI/CD automation, and I enjoy building solutions that reduce manual effort while improving security and performance.

My career began in the U.S. Navy, where I gained over two decades of experience in high-pressure, mission-critical environments. From operating patrol boats in Iraq to teaching survival skills at SERE school, and later supporting advanced geolocation platforms for Naval Special Warfare, I learned the importance of precision, resilience, and continuous improvement—qualities I now apply to every technical challenge.

Today I live in Chesapeake, VA with my wife and three children. When I’m not exploring the latest in Linux, Kubernetes, or cloud automation, you’ll often find me on the water with my family, experimenting with horticulture, or turning a wrench as a self-taught auto mechanic.

Garage Log

The Garage Log is an application to track maintenance on a fleet of vehicles. The user is able to add vehicles through a built in VIN search. Once a vehicle is added it can be modified or deleted. Each user may have multiple vehicles and each vehicle may have multiple maintenance logs associated with it.

- PocketBase
- Tailwind
User profile app

This is an application for registering and allowing users to sign in. Once signed in the user can update all of their information to include name, avatar, email, and password. This app has email verification. The frontend was built with Svelte and deployed on Netlify. For the backend I used PocketBase and deployed on Fly.io. This is by far my favorite tech-stack. Check it out, you can register with a fake email to test the features.

Small buisness blog

This is a site built for a small business that might want to reach customers with articles or blogs. The menu is a little different from the standard hamburger menu. It has an animated landing page with some graphics that I created using GIMP. The contact form is functional and I will receive messages there (probably not as fast as I would with an email). Check out the subtle color animation in the text.

Python web scraper

My wife grew tired of manually gathering data from a website and assembling it into a spreadsheet for her job. The task consumed hours of her time, prompting her to seek my assistance. In response, I developed a web scraper tailored to her needs. Tkinter facilitated the creation of a user-friendly interface, simplifying the process of entering login credentials. Selenium efficiently navigated the website and extracted the necessary data. Lastly, Pandas proved invaluable for data cleaning and formatting, ultimately generating an HTML document for easy access and analysis.

RGB Guessing Game

This is a guessing game that is great for anyone that uses RGB color. It was built using pure HTML, CSS, and JavaScript. It is linked to my CodePen page because I really like being able to showcase the game as well as the logic. Give it a try and see where you RGB guessing skills are.
