Founder at Principle Alchemy. Currently building our first product, InferaDB, a next-generation fine-grained authorization system inspired by Google Zanzibar and based on the emerging AuthZEN standard. InferaDB provides a strongly consistent, inference-driven policy engine designed for high scale, low latency, and developer-first integration. Our goal is to make authorization explainable, composable, and programmable - enabling developers to model complex relationships, define policies declaratively or via WASM modules, and deploy secure, auditable access control across distributed systems, APIs, and AI platforms.
Previously: Senior Engineer at Okta, where I led developer experience, authentication and authorization initiatives across Auth0 and OpenFGA. Before that, I helped build developer tools and crisis-response systems at Ushahidi, an experience that shaped my focus on security, privacy, and human-centered engineering.
Passionate about open source, digital wellbeing, and designing systems that last. Former game designer turned builder of better worlds — one product at a time.
