Long pieces on Venezuela's macroeconomy, on education, and on the plumbing that connects the two. Every chart names its source. Every model ships its assumptions, and you can change them in the browser.
Venezuela's exchange-rate regime from 2003 to 2026 and the path out of it: where the bolívar stands, where the economy must be by 2031, and the policy sequence that gets it there without asking the state to do the investing. An update of Bettocchi & Bolívar (2013).
More pieces in progress.
Fifteen years in software and finance: McKinsey, then product at two startups that got acquired.
Then I founded Open Minds Early School in Oakland with my wife, Karen Hernández.
Running a school teaches you where it breaks. Teaching is hard work; growing a school and keeping it solvent is harder. In Venezuela it is brutal: families want to pay and the money cannot get through. So we built UnoPago, the financial operating system for schools there: payments, billing and reconciliation in one place. A school that can collect is a school that can plan.
Before all this: aerospace engineering at MIT, economics at the Kennedy School.
Plenty of failures, a few things that worked, and something new to learn every day. Full CV at the CV.
