- <p> Hello, I'm JJ, and I go by j-james on the Internet. </p>
- <p> I'm a second-year student at the <a href="https://ubc.ca">University of British Columbia</a>, flag hunter for <a href="https://ubcctf.github.io">Maple Bacon</a>, embedded programmer on <a href="https://ubcbionics.com/">UBC Bionics</a>, and occasional ultimate frisbee and roller/ice hockey player.</p>
- <p> Outside of school, sports, and social life, I enjoy building and contributing to <a href="https://www.gnu.org/philosophy/free-sw">free-and-open-source</a> projects. The majority of my work can either be found on <a href="https://github.com/j-james">GitHub</a> or at <a href="https://sr.ht/~j-james">SourceHut</a>. </p>
