    About me

    I’ve spent more than 20 years building products and the teams behind them, working across design, engineering, architecture, and technology leadership.

    My best work starts with a difficult problem, not a finished spec. I help teams decide what to build, make the right technical calls early, and carry it through production.

    Founder & CTO of Immutable.
    Based in Milwaukee, Wisconsin.

    My Work

    Home Depot: Smooth, Engaging Customer Experiences

    Home Depot needed to turn aisle traffic into qualified service leads. I helped design and build unattended kiosks that captured intent and routed customers to the right contractors.

    GE Healthcare: Real-Time Conference Experiences

    GE needed a conference experience that could personalize thousands of attendee interactions, capture intent in real time, and survive an immovable event deadline. I helped shape and build the system from an intentionally incomplete starting point.

    Druva: Modern Sales Apps

    Druva had outgrown the spreadsheets behind its sales model. I helped turn the underlying logic into a secure application the sales organization could trust and use with customers.
