Senior Software Developer

Canada - Last active: 1 month ago - Tests: 2 - Portfolio: 2

I have extensive experience developing enterprise-grade network-based web applications and desktop software for clients in government, health care, finance, and academia. I'm the lead developer on several web-based and game engine products, some open-source. I'm strongly familiar with major proprietary and open source development tools and libraries. I'm both an experienced team leader and a fast and reliable solo developer, and as an entrepreneur I understand how to balance high-quality work with the need to ship. I have an academic background with training in both statistics and research methodologies, so I particularly enjoy working on challenging projects that require analysis and creative problem-solving, and which aren't simply clones of existing software. I look forward to working with you!

United States - Last active: 2 days ago

Well before the World Wide Web was a common phrase as it is today, before most people even owned a home computer I was programming code in a variety of languages for a variety of network related projects back when you had to put the handset of a telephone on a 300 baud modem. Trillions of lines of code under my belt and a mind that functions like a computer processing unit I not only understand today's most popular programming languages, I know how the languages themselves came to be. I am an expert who has owned, operated or worked with thousands of technology based businesses over the past 25 years. More than a programmer, I am a valuable consultant to any business wishing to build or improve any online enterprise. My work is relatively fast, accurate, functional and most importantly well constructed based on your exact needs. I do all of my own work but will bring in experts if necessary to accomplish the goals of your organization. I am an American living in Pennsylvania.
