Step 1
The Atom
Interfaces, icons, characters, logos. The smallest pieces of the work.

Step 2
The Pattern
Every popup on the platform was built ad-hoc. Different layouts per layer. Inconsistent data hierarchies. No shared components. Users screenshot these popups for their reports.
I identified common elements across fifty types, built a coherent system across nine data layers, and established patterns that made every new data source faster to ship.

50+ popup types · 9 data layers · One system.
I sketch to think, play football to not think, and measure coffee extraction like it's a design variable.

Step 3
The Feature
Two tools. No connection between them.
Two tools for 2,340 cameras. Neither saved your layout. I watched operators work, then designed the wall they could build, name, and keep.
Build a wall. Name it. Come back to it tomorrow.
Same wall, different density. Six cameras or sixty.
List. Search. Map. Find any camera three ways.

Step 4
The Product
Vessel data existed but no one could see the full picture. Port authorities needed real-time movement patterns, dwell times, and throughput in a single view.
I designed the analytics dashboard they use today. Live in production. Presented at TRB 2025.
Analytics for vessel movement: where ships go, where they wait, and what they pay to avoid a queue.
Maritime Trip Analytics, 2024
01
Hex bins, not route lines
Roads give traffic a fixed width; ships follow currents and common paths. I pushed for hex bins over route lines, and the team adopted them. They hold up from a single port to the whole globe.
02
Bin size, separate from zoom
Our tools clustered by zoom: zoom out for the big picture, zoom in for detail. I made bin size its own control, so at the same zoom analysts see both the overall routes and the detail inside them.
03
Filter the result, don't re-run the query
Our tools had you describe a query, then run it. Adding one day meant starting over. I pushed the PM and stakeholders for live filtering, which maritime needs and other datasets can use too.
04
A "through" filter
The job is finding the best route, and chokepoints decide it. If the Panama queue runs 5 to 10 days, a ship might arrive sooner another way. "Through" finds every vessel that passed a region, so analysts can spot delays and compare alternatives.

Outcome
The first tool in our suite with live filtering
It's now in 5 more. The dashboard I designed now serves other datasets, from truck parking to land vehicles. Presented at TRB 2025.

Four design decisions behind a maritime analytics tool
Ssongs
Browser-based ordering that removes the queue and adds a weekly game. No download. 84% of testers preferred it.
Away-sis
HoloLens meditation for ChristianaCare caregivers, designed for the way out as much as the way in. Stress measured through biosignals, not surveys.

Ssongs · Ordering for a Korean hotdog shop
A browser-based ordering app that removes the queue and gives the wait a purpose: a weekly game with rankings and rewards. No download.
Problem. At a food court you queue to order, struggle to find a seat, and have nothing to do while you wait. Tablets at the counter don't fix that.
Decisions.
Scan, don't install. QR ordering in the browser. Nobody wants to download a hundred food apps.
A weekly game. Three games rotate each week, with rankings and rewards for the top 3. The team made three; I made one myself: Red Light Green Light, themed on Squid Game, which was everywhere at the time and fit a Korean shop.
Customization you can see. Picking options visually instead of from words made custom orders easier.
Tradeoff. A game that holds your attention can make you miss your order. So the live order timer and a ready notification stay on top of the game.
Outcome. 84% of 19 test participants preferred it over the existing process. 31 heuristic issues found across 5 sprints in 7 months. Delivered with a style guide and component library.
Browser-based · 7 months, 5 sprints · Usability tested with 19 participants
Away-sis · HoloLens meditation for ChristianaCare
Most meditation apps focus on getting in and staying in. Away-sis also designs the way out.
Problem. Guided meditations open with a relaxing voice or sound that fades away, then end with an abrupt voice announcing it's over.
Decisions.
A sequence for every sense. Day slows into night, then into a state with all color removed. Sound starts natural, gains birdsong, then instruments.
Breathing you can see. In the colorless state, a colored breathing cue gradually brings the respiratory rate down.
A way back. Sound fades in and out as color and night birds return, then morning birds bring you out.
Start with a look. The first version needed a controller to begin. We replaced it with a bubble you look at for a few seconds.
Measured live. The HoloLens tracked respiratory rate, heart rate and other signals, and showed a live graph of the wearer's cognitive load as it changed.
Tradeoff. It was a short project: a home space and one meditation space. We modelled everything in the meditation space and some of the home space, and took the rest from online libraries, so the two share a theme but not an identical style. I modelled a panda spirit animal in Blender, but its interaction didn't make it in.
Outcome. Tested with 40 caregivers, including doctors and nurses. Most liked it, but not everyone was ready to adopt it straight away; gradual exposure would have helped. Over 20 days of our own recordings, cognitive load dropped gradually.
