Software Development
I've been doing full life cycle software development professionally since 1984. I have worked on a wide range of systems and applications, from large scale database applications through to high performance gaming systems. Though I have experience at the executive level I still find tremendous joy in writing code, building applications and architecting systems.
I am currently offering software development services on a contract basis. My most recent experience is doing full stack, cloud based web applications with Ruby on Rails. If you need an application built from scratch or need an application modified or updated, let's talk.
David Alison has been a tremendous asset to our website development team. He came on board during a crucial time of our development and was able to bring some high-visibility features from idea to implementation ahead of schedule and in a format that was intuitive for our users.
One of the best things about working with David is his ability to hone in on a "third option"; whereas I might be stuck between this idea or that idea, David is able to see through to the heart of the issue and come up with another way of solving a problem that meets the need better than any other proposed solution. Beyond his highly capable technical prowess--he is just a great guy. David has such a positive, can-do attitude and collaborating with him on our projects has really been a joy. He works confidently and quickly and his dependability has been unmatched. I am eager to continue working with him in the future.
