Profile bio

About Billy Mathison

I am a problem solver.I spent 16 years working in mental health, helping others solve their problems. Eventually I came to the realization that while I loved helping clients through their problems, ultimately I had no control over the final outcome.What I love most about being a software developer is that I have the ability to solve any problem. I still have the satisfaction of breaking something apart and trying to understand what the issue is. Now, I also get to solve that problem. There is something so incredibly satisfying about not only being able to understand the problem, but being able to create a solution and implement it.Software development has allowed me to expand upon a part of my previous career that I enjoyed most while also providing the ability to directly solve a problem.

Listed skills include Leadership, Asp.Net Mvc, Git, Ethics, and 35 others.
