The missing manual on how to build payment systems

The Payments Engineer Playbook is for anyone who wants to build correct money software on time and on budget.

Every week I look at some critical aspect of payments software. And I extract a tactic, a useful insight, or a design guideline that’s helpful for payments engineers.

Who am I

My name is Alvaro Duran. I’ve been building software that moves money around both at MegaCorp and at tiny.co. And I’m now part of the Fintech team at Kiwi.com, responsible for each of the 70,000 times a day a customer clicks the Pay button on our platform.

As part of that team, I’m on many conversations about what works and what doesn’t for payments software.

These are the conversations that inspired this newsletter.

What you’ll get from me

That sounds good, right? Then just write your primary email down below.
