I worked on a few different things at Stripe from direct to platform products. For the first half of my time at Stripe I was an engineer on a small team of about ~7 people that worked on the Stripe Corporate Card. This was one of Stripe's first direct (non API) products and we had to build a lot of stuff ourselves to get this launched. I was directly responsible for a lost of our integration which Stripe Issuing, our rewards system, ATM functionality, our notifications system and eventually our user onboarding system.
Later on I worked on Stripe Issuing and Treasury which is Stripe's API that lets users add banking products and issue cards in their applications. I was directly responsible for a lot of our integrations with our partner banks which included building a lot of infrastructure needed to make our product fully regulated.
I worked as a backend engineer for the first half of my time here adding new end-to-end features to the Nylas API for our users. Later on I worked on more platform stuff, building tools for other engineers at Nylas to use including logging and storage infrastructure
