Co-founder & CTO at RavenEye.ai
I build products in emerging categories before they go mainstream—browser-based content management in 2002, a year before WordPress; prediction markets in 2006, a decade before Kalshi and Polymarket; Amazon market share analytics in 2014 (acquired 2016, scaled to $30M+ revenue); LLM-powered tools in 2023; and now computer vision for retail. I specialize in identifying whitespace early, shipping fast, and bridging technical possibility with market readiness.
computer vision · 2025–
Retail-ops machine vision, built for convenience stores. RavenEye turns the cameras a store already has into real-time operational intelligence: every out-of-stock, empty bay, and missed delivery, caught and closed before it costs a sale.
LLMs · 2023–
One AI workspace for resumes and hiring. A multi-agent LLM workflow across Anthropic and OpenAI, serving several hundred people a day.
coding agents · 2026
Cross-provider coordination for coding agents. A shared record that lets many agents work the same codebase and surfaces collisions before they happen.
2018–2023
Built Ascential’s first enterprise data science and ML function, with ML products generating $30M+ a year and a team across Dublin, London, Boston, and Salt Lake City.
2014–2018
The first commercial, at-scale ML approach to predicting Amazon market share and sales—a category that later became industry standard.
2011–2013
Built the Online Film Guide (5M+ page views a festival) and the REST API behind Sundance’s mobile apps.
2011
Car Pool Party, written so my fiancée’s carpool could stop arguing about whose turn it was, and LocaDo, location-based to-dos.
2005–2014
I was giving tours at Utah Olympic Park, and the employee discount on the intro camp got me onto a sled. Head first at up to 87 mph (Whistler), inches off the ice. Bronze at the Königssee Europa Cup (2011) and the Park City Intercontinental Cup (2012), 19th in the Altenberg World Cup (2013), and a world ranking as high as 27 on the road toward Sochi.
2006–2008
A prediction market for real-world events with its own automated market maker, built solo more than a decade before Kalshi and Polymarket.
2005–2012
The second-largest RSS feed directory on the web: 15 million pages and 1.4 million visitors a month, run on three VPS boxes.
2003–2008
After college I moved to Park City and co-founded Jupiter Peak Lodging: three properties and 15 vacation-rental units around Old Town, starting with a four-plex we renovated in 2003. I ran day-to-day operations—check-ins and check-outs, cleaning, maintenance, and the books—and built its sites and owner extranet, then DestinationOwners.com, the booking engine that ran them by 2005.
2001–2002
A content-management shop I started in college, built on CoYoSi, my own CMS that let clients edit their sites from any web browser—a year before WordPress shipped. Clients included Big Brothers Big Sisters of Milwaukee and Waukesha Counties and Marquette University. It went by Grey Duck Productions in 1998 (duck, duck, grey duck—it’s a Minnesota thing) and Brad Stewart Productions in 1999.
1998–2002
Three years as Apple’s campus rep for Milwaukee’s colleges—Marquette, UW–Milwaukee, MSOE, and MIAD—and president of Marquette’s Mac Users Group. Summers at West Group, temping on data entry in 1998 and back in 1999 building websites for law firms, then 2000 and 2001 in GE Medical Systems’ Information Management Leadership Program.
1998–1999
Freshman year I rebuilt the College of Communication’s website for the New Media Center. As student government’s multimedia director I built its sites, including a course guide professors filled in themselves: an early swing at professor reviews, the same spring RateMyProfessors launched. On the side I sketched yourCollege Online, where students would rate schools on housing, food, social life, and diversity.
1998
Mac desktop pictures from my travels, launched on AOL on July 17, 1998, the summer after high school. A MacAddict “link du jour” that September sent it past 3,000 hits, and it passed 10,000 within a year. It led to designing the MacAddict Readers Club site with MacAddict magazine and moderating its forums, and my early work got write-ups in the St. Paul Pioneer Press, MacAddict, and The Marquette Tribune.
1996
A fan site for The Cure, plus a smaller one for The Clash, hand-coded on my AOL account in high school. It was live by October 1996, when I asked a Cure mailing list for their sites: “why create a lame page when alot more people have awesome pages!” Offline I was tech editor and co-editor-in-chief of the school paper, the Raiders’ Digest: we put out its first color issue, and I hosted its website on that same AOL account.
