Luke Blommesteyn
I work on ML and analytics infrastructure at Lyft in Toronto.
Outside of work I do sports analytics research, mostly basketball tracking and roster building, and take apart chips and models to see how they work.

Holes in the Defense
Broadcast tracking turned into a field of exploitable court space, then screens, drives, passes and closeouts scored in the same units.
Rebuilding the Wires
Turning a chip layout back into a circuit a solver can drive. One of Jane Street's favourite submissions.
B.A.I.L.I.F.F.
Mock trials where only the defendant's name changes. Fair-looking verdicts, unequal trials.
GroupWAR
Scoring national-team rosters as a group instead of a sum of individual WAR.
