I design complex systems people can actually use

Program catalogs, associate tools, review workflows. I work on the systems where people cannot find what they need, or cannot tell what to fix first, and I build the standards and training that keep them working.

Selected work

Projects, and the decisions behind them

Two phone screens of the shipped Program Explorer. The front one shows the Refine Results panel open, with Program Type filters for undergraduate major, undergraduate minor, master’s, doctoral and certificate. Behind it, the results list shows program cards, each carrying a photograph, the degree type, a one-line description and the format.

ACES Program Explorer

I designed and led an interest-based Program Explorer that helped prospective students browse a growing academic catalog without needing to understand the college’s department structure first.

Two phones at an angle, each showing a Walmart product. On careers.walmart.com, a staff pharmacist posting with an Apply now control. On walmart.com, the Spark Good page headed "Organization resources designed for you", describing local grants and a space request tool for nonprofits.

Touchpoint portfolio strategy

I built one decision system for roughly 80 touchpoints, so accessibility support could follow risk rather than visibility. A reorganization had just put all of them under one organization, and the support model that came with them had been built for a fraction of the work.

Three overlapping social posts from Hedgerow Pottery. The owner holds up a teal t-shirt printed with the round Hedgerow Pottery mark. A winter classes and workshops graphic carries the same mark at its center, over a grid of studio photographs. A hand holds a green glazed mug with the mark pressed into the clay.

Hedgerow Pottery identity system

I turned a fragile logo file into a production-ready identity system, giving Hedgerow Pottery a guidebook, vendor-ready assets, and a brand toolkit that could work in real production without constant design translation.

Speaking & teaching · 2020–2025

Presentations & knowledge sharing

Invited talks and teaching where I turn complex experience, design-system, and governance work into a shared direction teams and leaders can act on.

How I work

The design and the system around it are the same job

Design the experience

I turn complex content, needs, and constraints into clear interaction models, information architecture, and accessible behavior.

Make the standard usable

I create written guidance, review paths, and decision tools that help teams catch issues earlier and avoid solving the same problem again.

Build judgment

I use coaching, training, shared tools, and clear escalation paths to help people become more capable, not more dependent.

Make tradeoffs visible

I bring product, engineering, business, and design into the same conversation when a decision affects the experience, the team, or both.
