Founder & Engineer
Currently building AI-powered, agentic experiences in M365 Copilot at Microsoft. Before that I founded Oark Library. I grew it from nothing to 130,000 users with almost no marketing budget, then wound it down on my own terms. I hold an MSc in Data Science from Strathmore, write at ToKnow.ai, and building Blober.io.
I build things I think should exist.
- Blober.io: local-first workflow engine for cloud storage transfers. Credentials never leave your machine.
- ToKnow.ai: data-driven research on AI, security, and finance
- @mckabue/react-validate: type-safe React form validation hook, zero dependencies
- @mckabue/react-use-async: React hook for async state with loading, error, and merge
- @mckabue/no-same-type-params: ESLint rule against same-type adjacent parameters
