01 / The person

A few things that connect the dots.

From the operating room
to the next useful idea.

In 2017, I worked beside operating-room teams at Stryker, troubleshooting endoscopy equipment during procedures and helping staff learn the technology.

I moved into emergency-care sales in 2018. In 2021, I added volunteer fire and medical response with Oconee County Fire Rescue. Today, I both explain equipment to the people who depend on it and stay involved in the work firsthand.

That interest in how things work also led me to build CaliberAtlas. I chose to keep its core tools free and make the sources and assumptions visible. People can use the reference, inspect the methods, and question the results.

See that approach in practice

02 / Selected work

Willis Innovations

Curiosity,
put to work.

Through Willis Innovations, I choose the problems, direct the research and product work, and decide what is ready to publish. These are examples you can explore.

REFERENCE & DECISION TOOLS01

CaliberAtlas

From scattered ballistics data to a transparent decision tool. The challenge: making cartridge information useful while keeping its sources and assumptions inspectable.

Builder and operator: research direction, product decisions, and quality standards.

04 / How I work with AI

Curiosity needs a process.

Bring one task.
Find a useful next step.

For founders and business teams exploring AI in everyday research and administration.

One example from my own work. For CaliberAtlas, I use AI to help organize source material and develop tools, then check the results against published methods and reference data. I own the scope, review, and publication decisions. Read the methodology

A working session with a concrete aim.

Start with one non-sensitive research question or repetitive administrative task. We can map the inputs, walk through an approach, and identify where a person needs to check the work.

The aim is a written workflow outline you can reuse: inputs, steps, review checks, and a next experiment. Any prototype or ongoing work would be scoped separately.

These are independent conversations through Willis Innovations. We start by confirming fit and scope.
