Howdy! Evan here. 👋

Co-founder and CTO at InferaDB, the authorization database: Zanzibar-inspired, AuthZEN-compliant, and purpose-built for fine-grained access control at scale. The goal is to make authorization explainable and composable. Developers can model relationships, define policies declaratively or as WASM modules, and ship auditable access control across services, APIs, and AI agents.

Previously: a founding engineer on the OpenFGA team at Okta, where we shipped one of the first Google Zanzibar-inspired ReBAC solutions to market: OpenFGA and the Auth0 FGA SaaS built on it. OpenFGA is now a CNCF incubating project used by Grafana Labs, Docker, and Canonical. Before that, an early engineer on Auth0's developer experience team, shipping 45+ open source libraries used by enterprise customers. Earlier still, I helped build crisis-response tools at Ushahidi, with deployments at the United Nations and during the Fukushima disaster response. That work taught me to take security, privacy, and the people on the other end of the software seriously.

Open source, digital wellbeing, systems built to last. Former game designer; the instinct for building experiences people actually want never quite leaves you.
