Ethan Vanderbur
Full-Stack Web Developer with 10 Years of Experience.
I'm a passionate full-stack developer with professional experience in the United States Marine Corps. I'm driven by solving complex problems and building scalable systems, leveraging expertise in Java, Spring, and SQL to create software that has real-world impact.
About Me
I began my journey into software development during my sophomore year of college, after realizing that graphic design wasn't the right fit for me. Drawing on my early exposure to Visual Basic in high school, I pivoted toward programming and quickly developed a strong interest in Java and C#. Java, in particular, became my language of choice, and I’ve been building with it ever since.
My professional experience as a full-stack Java developer in the United States Marine Corps has solidified my passion for solving complex problems, building scalable systems, and working on projects that have real-world impact. One of the most rewarding aspects of my role was contributing to systems that directly affect Marines—ensuring their pay is accurate and timely.
Throughout my career, I’ve contributed to a range of high-impact projects, from developing new system modules to managing critical transitions between legacy and modern platforms. These experiences have deepened my expertise in Java, Spring 5, Oracle SQL, and SOAP-based web services.
I’m now seeking a mid-level engineering position where I can continue honing my craft in hands-on development, especially with Java, Spring, and SQL. While I’m fully capable of taking on senior-level responsibilities, I’m most energized when I’m writing code, solving real problems, and making software work better.
