## Off the clock
Guitar and family, one frame each.
- Electric guitar (since 2015): Self-taught on a Strat. Learned to practise the boring part slowly — same as debugging.
- Family tree (Madrid ↔ Texas): Two countries in the same branch: the reason I studied on both sides of the ocean.
Goals: Lead the platform side of an integration team, and ship open source other engineers depend on.
