The amount of energy needed to refute bullshit is an order of magnitude bigger than that needed to produce it

Hi! 👋 I'm Frank de Jonge

I'm an all-over-the-stack software engineer and I'm a builder at Duna. We help regulated companies safely onboard new customers faster, with higher conversion.

We're changing how companies stay compliant.

Projects I've worked on

The work I'm most known for is Flysystem, a filesystem abstraction for PHP. I've also authored EventSauce, an event-sourcing toolset for PHP. My latest open source project is Flystorage, a filesystem abstraction written in TypeScript.

The open source software I maintain have been downloaded over a billion times. At least 1 out of every 91 or 1.094% of all packages downloaded from Packagist was authored by me. Across all packages, they have been downloaded 1,505,802,635 times.
