About
I started out in statistics because I liked puzzles, and stayed because I found out data could start arguments at dinner. My favourite projects answer questions normal people actually ask.
I care about clean methods, honest uncertainty and charts that a tired person can read on the bus.
Off the laptop I play basketball, try every prata shop I can find, and I'm learning the guitar badly.
