  Cambridge, United Kingdom I spent a few months after AHL working on random freelance/personal projects: * Created Kimonote (https://kimonote.com), a text-first note organizer / blogging platform that focuses on minimalism and ease of navigation. * Tried developing several quantitative trading strategies for Betfair, a betting exchange.

Whilst I didn't make money, the writeups (https://kimonote.com/@mildbyte:betfair) received good feedback and led to multiple valuable contacts in the professional gambling industry. * Wrote several essays/articles that made the front page of Hacker News (news.ycombinator.com): ** "Against the synchronous society" (https://kimonote.com/@mildbyte/against-the-synchronous-society-3146/) about the strain on infrastructure from people doing the same things at the same time; ** "I've never felt less in control of my own hardware" (https://www.kimonote.com/@mildbyte/ive-never-felt-less-in-control-of-my-own-hardware-14804/) about how automatic updates have made it acceptable to not really know or control what's running on one's own device. This one spent about a day as the #1 post on Hacker News. * Wrote a simulated annealing (genetic algorithms) optimiser that I used to generate a speedrun route through all faction quests in the computer game Morrowind (https://www.kimonote.com/@mildbyte:morrowind/). This resulted in another couple of front page HN posts as well as "All Factions" being made an official Morrowind speedrun category (https://www.speedrun.com/morrowind#All_Factions). Show less

  • Jun 2013 - Aug 2013

  Worked in a team that provided libraries and other support for Python and Perl developers at the Firm. Wrote a plugin for Eclipse with PyDev that solved a problem related to how Perl/Python packages are deployed. This problem made it extremely inconvenient for the developers to use an IDE with Perl or Python and thus solving it greatly improved their workflow. Also improved documentation on how to use Perl and Python within the Firm.
