NeKz
From P2SR Wiki
NeKz was a technically-minded individual that helped bring Portal 2 speedrunning to the point at which it stands today, pioneering the SAR plugin and building a number of helpful websites including the Least Portals (LP) leaderboard and the demo parser which was used to time runs for a long time, although less utilized now due to the growth of SAR. Over time, his presence has faded from the community, and now his only active contribution is the moderation of the LP leaderboards and the maintaining of other useful website utilities such as the parser.
