Member since February 24, 2016

Paul has had the pleasure of working with a wide variety of technologies since teaching himself TI-BASIC 15 years ago. Most comfortable with Ruby and Python, he is familiar with other tech stacks and always eager to learn new ones. Paul's studies were focused on database design and software architecture, and since then, he has also focused on RESTful API development. He is passionate about writing elegant code that runs well and reads well.
