Hey, I'm John 👋

Where I've built

Replit Webflow Atlassian Twitch Slack GitHub Salesforce

For nearly 30 years I've been the person companies call when they're scaling a developer platform. I join at the inflection point — ship the APIs, SDKs, marketplaces, and partner integrations that get them there — and move when the platform motion matures.

I started as an engineer and a founder, building one of the first online mortgage platforms before "fintech" was a word, then a banking-API company that gave credit unions the developer surface to ship modern products. That founder instinct never went away.

After a decade leading developer-platform orgs through Director and VP roles, I returned to the hands-on craft in 2025. The best work I've done has always been technical — API surfaces, partner integrations, the 0→1 platform launches. The org chart was never the point.

Currently

Principal at Aganomix — advising developer-platform founders at the seed stage and working with enterprises on AI and developer-experience strategy. Based in Chicago, active in the Midwest startup community, and always making time for developers building something worth building.
