I worked on Stripe's core payment APIs [0], helping to build out some next generation infrastructure to scale more payment methods and payment volume. Before that, I was tech lead on Stripe Atlas, automating the workflow for incorporating a company and helping launch LLCs, a new banking partner, and taxes support [1].

I built a site dedicated to teaching others how to become full-stack engineers. That includes all aspects of engineering, not just algorithms or data structures. Things like build systems, testing, how to design a solution for a problem, how to iterate on that solution, frontend and backend work, etc.The site itself is built with Haskell, and you can find it at https://fullstack.industries

Worked on the Galaxy backend team, building out Meteor's Platform-as-a-Service offering. Built software that hosted Meteor apps in Amazon's Elastic Container Service, managing docker deployments across multiple availability zones.I focused mostly on the scheduler, a Go program that makes sure customer's containers are always up and distributed evenly across the system, handling failures and maximizing availability. I also designed a system for how we can migrate our infrastructure during upgrades without downtime and allowing for quick rollback if things go wrong. We didn't finish executing on this plan while I was there, but we had made significant progress.
