About the practice

Business understanding.
Technical direction.

I’m Danielle McKee, and Arc Theory is my independent practice. I help teams understand what needs to change, translate it into a practical technical design, and lead the implementation.

The idea behind the name

A simple shape.
A way of thinking.

Graphic design is the art I’ve always felt most at home in. Geometry gives me a way in: simple shapes, arranged with intention, can become something entirely different.

An arc is such a simple shape, yet it does so much in architecture. I’m drawn to the idea that even something complex can be understood through simpler forms.

I approach systems the same way: thinking in modules, combining simple pieces, and borrowing ideas across tools and types of systems. The best solution doesn’t always need to be the most technically sophisticated. Sometimes it’s the simplest arrangement that works.

The person behind the practice

I’m Danielle.

My background spans finance, operations transformation, enterprise systems, and hands-on technical delivery. Working across these roles has taught me to look at the business need, the people doing the work, and the technical constraints together.

My role varies by engagement. I work as a solutions architect, technical lead, or fractional technology partner. I connect what the team needs with the workflows, requirements, and technical decisions that make it possible.

Tangrams

The possibility
is in the pieces.

I used to play tangrams with my dad. A small set of simple shapes could become something entirely different, just by changing how the pieces fit together.

That idea feels connected to the work I do now. The possibility is often already in the pieces we have. It takes a different arrangement to see it.

As humans, we tend toward complexity. We add a tool, another process, another workaround. My instinct is to step back: what are the essential pieces, and how could they work together more clearly?
