Ethan in a few words

I've been a web developer for over 6 years. I've got experience in everything from simple websites to full-scale applications. I'm happy to help you build whole projects from the ground up or jump into an existing project for small changes or improvements. My goal is for you to be 100% satisfied with the software that I produce. I make a point to communicate consistently with clients at every step in the development life cycle. This allows the customer to stay up-to-date on a project's progress, and allows the customer to give feedback on a project's progress. I have found that this leads to software being produced of the highest possible quality.
