Engineering, leadership, and hands-on problem solving.

My work spans frontend technical leadership, cybersecurity and red-team automation at Rebellion Defense; geospatial mission visualization and planning at Northrop Grumman; and interactive software, advanced interfaces, and immersive prototypes at Applied Minds.

Across these roles, I've translated complex customer needs into usable systems, led technical delivery and demonstrations, mentored engineers, and worked closely with users.

Experience beyond the portfolio

Much of the work isn't public.

These projects are only a small sample of my engineering experience. Much of my work has been in defense and other sensitive technical environments, where confidentiality and project restrictions mean source code, interfaces, and implementation details cannot be shared publicly.

Engineering + product thinking

How I work.

I bring together technical leadership, frontend engineering, and a strong understanding of users and systems—turning sophisticated requirements into clear, reliable products.
