Freelance Full Stack
Web App Developer

About Me

I'm a freelance full stack web app developer. I've worked on other types software and different aspects of the development lifecycle (mobile apps, APIs, CI/CD pipelines) over the last ten years of professional software development. But I primarily develop web applications for small organizations, startups, and individuals using modern tech.

Software development is more than designing and implementing a software system that accomplishes the desired goal. It starts at the idea. Why are we building this? How do we build it in a way that efficiently and effectively accomplishes that goal? I so enjoy looking at the big picture and then diving down into the details. This full process is what makes me enjoy software development.

My life and my work are intermingled. I'm a skier, climber, mountain biker, traveler, and hobbyist. Those things are a huge part of who I am and they've shaped how I approach problems and live my life.
