I'm Juan Manuel Medina — Jota.
Half product manager, half engineer. For the last few years I've shipped software people actually use — across banking (Santander), energy (Copec), and my own startups (Surfari, LazyBenchmarks, and a few nights-and-weekends builds).
Today I lead product for AI agents at AgendaPro (YC W21), building AI that does real work for real businesses. Taste, judgment, knowing which problem is worth solving — you can't prompt that. This site is a small reminder.
