    Senior Software Developer

    Canada - Last active: 8 days 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!
