About Me
Hello! I'm Seth, a full stack software engineer with a passion for creating dynamic and intuitive web applications. My journey into programming began with a curiosity for how websites worked, which quickly blossomed into a full-fledged career dedicated to crafting high-quality code and user-friendly interfaces.
With experience across the full stack, I work with modern web technologies on the front-end and have strong back-end expertise with Java and C#. I enjoy bringing ideas to life, from the initial concept to the final deployment, whether it's building scalable enterprise applications or elegant user interfaces. I'm also an avid GitHub Copilot and Claude Code user, leveraging AI-assisted development to work faster and smarter.
