Hi everyone - my name is Andrew Arruda, I'm at https://andrewarruda.substack.com. And I'm writing mostly about digital health and health data interoperability but also on things I find fascinating like the recent retail investor movement and the like. I'd give a shout-out to Josh Kelly, https://joshuakelly.substack.com/, who writes about healthcare, technology, and money. You can also find me on Twitter here: https://twitter.com/AndrewArruda
