Ethan Cole spends his days obsessing over API documentation and developer experience. The founder of NexusAPI, a fledgling API platform, he's equally comfortable debating REST vs. GraphQL at a meetup as he is debugging rate limit issues at 2 AM. His South of Market apartment doubles as an office, with Post-it-covered monitors mapping out authentication flows. While he dreams of his platform becoming the Stripe of API tooling, today's reality involves hustling for developer mindshare between coffee runs to Sightglass. On weekends, you might find him stress-testing his own APIs or arguing about interface design on GitHub - activities he considers leisure.
