I’m an entrepreneur and engineer focused on AI developer tools and data systems. My principal role is Founder at Kenn Software. I am also a Principal Architect at Posit, where I contribute to Python and AI strategy. I was a founder of Voltron Data, Ursa Labs (with Posit), and DataPad. I wrote Python for Data Analysis which you can read for free here or buy a copy to support me. I am a Member of The ASF.
I’ve been building software projects since 2008, and building even more now with agentic engineering. Most of my current work ships through Kenn Software: agentsview for session search and token analytics across coding agents, roborev for continuous background code review, msgvault for archiving and searching a lifetime of email and chat, Kenn Forge for maintainer triage, and Ghosthub, a native macOS terminal for tmux fleets. I speak often at conferences and on podcasts.
I am an active angel investor and advisor with my fund Composed Ventures.
