I turn how people actually behave into data stories that change decisions.
Analytics, experiments and visualization that show what audiences really do, then make the decision obvious.
The magazine
D.C. Issue 01 is an 80-page print magazine that doubles as my CV: the résumé in words and then as data, eight data stories, how I work, an essay and the apps I build. The whole issue is online, page by page.
Holding a printed copy? The QR codes inside open the live stories.
Shoes of the Marine Corps Marathon
I filmed every runner who passed me at mile 21 of the 2026 Marine Corps Marathon and ran the footage through a shoe-ID program I built. Nike led with 25.6% of identified shoes, but its share fell from 42% to 18% as the field slowed, and the Nike Alphafly was the most-worn model.
October 2026. Watch the reel, then tap any brand to see where its runners were on the course.
Swingboard
Thirteen what-if chapters for the November 3 midterms, played out race by race on the maps nine states redrew for 2026: the Iran war’s $4 gas, the Canada trade fight, abortion bans, Latino and young voters, federal job cuts. The finding that runs through all of them: one shock moves the House, but it takes several at once to move the Senate.
October 2026. Real Census electorates in every district; click any race to see it county by county.
Open Spots
I read the public booking schedules of 42 Arlington studios every hour for a week, then rebuilt each day as a 3D world. Every figure is a real booking, every empty mat an open spot. Classes ran 45% full; [solidcore] holds 7 of the 10 hardest to book.
October 2026. Walk the floor, sort by gym, open any class, or switch to the seat map.
EFL Table
Every week I simulate the rest of the Championship season 10,000 times from the live table, the remaining fixtures and the bookmakers' odds. Every club gets a projected finish, every fixture a prediction.
2026–27 season, updated weekly. Compare four ways to call the final table, or open any of the 24 team pages.
The DC Half, decoded
I filmed the race from the sidewalk, taught a vision pipeline to name thousands of shoes, pulled the results apart, then rebuilt the whole race as a replay.
Two are Instagram-style stories: tap or swipe on a phone, arrow keys on a desktop. The replay is a live map.
Ideas are powerful. Opinions are dangerous. Everyone needs to show the data.
