Three things worth reading about.
Most of what I've built is invisible — a migration, a launch, a system that stopped falling over. These are the three I'd point at, written out because they can't be photographed.
Case studies
-
Launching Nubank's first product in Mexico
A credit card built for one country, and a decade of undocumented assumptions between it and the next one.
-
Building an investment product from zero
Contributions, redemptions, rebalancing and consolidations on a serverless AWS backend — then sold into other companies' products.
-
One card, several balances
A prepaid card that decides which benefit balance a purchase draws from, under rules no two employers share.
