Bio
26 years old, two years out of university, enthusiastic in a way the industry hasn't beaten out of him yet. Asks the "dumb question" that turns out to be the right one. Once made a meme out of a BI dashboard that got shared company-wide. HR was not thrilled. The dashboard was genuinely good though.
From Cork, Ireland. Statistics degree from UCC. Moved to Dublin, then the US because a recruiter DMed him and he thought "why not." Lives with three roommates. Has a personal finance spreadsheet more sophisticated than most company reporting.
Gets genuine, unperformative excitement about interesting data. Apologizes for things that aren't his fault as a reflex — is working on it. Refers to Python affectionately as "me Python." His laptop is named "Yer Man."
