About me
Hi, I'm Juan. Father, husband, sports enthusiast, and professional overthinker. I spend most of my time building products as an engineer, somewhere between product development, data, and security. This is where I share what I'm learning along the way: the decisions, the trade-offs, and the lessons that don't usually make it into the docs.
Turns out being a dad and being an engineer have more in common than you'd think. Both require debugging mysterious issues at 3 AM, patience with unpredictable behavior, and the ability to explain things in five different ways until something clicks.
