I'm a product design leader focused on B2B developer tools, messaging platforms, and AI-powered software. I've spent most of my career at venture-backed startups, often as the first design hire, building design teams and shipping products used by hundreds of thousands of developers.

I like to work lean and research-driven. I care about shipping end-to-end, from early discovery and rapid prototyping through to polished UI and production code. I've taken multiple products from zero to one and scaled design teams through acquisition.

I have a Masters in Multi-Disciplinary Design from University of Ulster Belfast. Currently VP of Design at OneSignal, where I lead design across product design, visual communications, and design engineering. Before that I led design and product teams at Mesosphere (acquired by Nutanix), Mailgun (acquired by Rackspace), Kareo, and Runnable (acquired by MuleSoft). Take a look at my portfolio for examples of my work.
