I am building Moonlight while traveling full-time. I like Go, Kubernetes, Vue.js, Julia, optimization mathematics, Python, and distributed systems. I graduated from Washington University in St. Louis where I studied applied math and majored in Systems Engineering and Physics. My education continued at Y Combinator, where I was a Fellow in their inaugural class. I founded Staffjoy, a startup that used optimization math to manage workforce scheduling.
