Unknown Behavior Independent Practice
I'm Katherine. I build consumer products people open every night, and the partner and ad businesses that pay for them. Exhibit A is ZONA, a Miami nightlife platform I took to 150K+ downloads and 25+ venue partners.
Selected work
The product, and the business underneath it.
The flagship. A real-time Miami nightlife platform I started in 2023 and launched in 2024. I led the team that shipped it across iOS and Android and took it to 150K+ downloads and 25+ venue partners, then built the business underneath: a partner portal, an ads product, and a lifecycle engine. Owned end to end, product to revenue.
An NYU Berlin team project I led. We took a vague idea and shaped it into a focused product: runtime governance for AI in medication. We presented to Google and Join Capital and won the final pitch before a faculty panel. Sentra is middleware between an AI prescription system and the pharmacy: it validates every AI-generated medication order against live patient data and returns allow, block, or escalate in under 100 milliseconds, with an audit trail built to the EU AI Act. AI safety, applied where being wrong is not an option.
A multi-vendor integration was quietly leaking bad data. I found the breaks, built validation at every join, and put it all in one view leadership could actually read. Mismatches down 25%, manual reporting down 40%, breaks caught at ingest instead of weeks later.
Surfaces
The products and platforms, consumer and B2B.
The ZONA app: real-time nightlife, where tonight is actually happening, across iOS and Android.
zona.miami: 500+ programmatic venue and event pages indexed on Google and Bing, turning Miami nightlife searches into organic discovery.
The getzona.app header CTA, treated as a growth lever. A device-aware Download button that routes iPhone to the App Store and Android to Google Play, consistent across all 10 pages, with every click instrumented in GA4 and an automated weekly click-through-rate report. Pointed at installs and measured, not guessed.
The supply-side data layer the decision engine runs on. I built the pipeline that keeps 400+ venues accurate and current, reconciled against authoritative sources like Google Places, because 'where is open tonight' is only as good as the data beneath it.
ZONA's retention runs on push, so I built the nightly decision engine that picks who gets messaged and when, under hard guardrails like frequency caps, recency floors, and open-rate backoff, and monitors its own tap rates to pause weak triggers. Lifecycle, not blasts.
A live ranking of every venue by real-time demand, using an exponential time-decay model so current momentum outweighs history. It shows each venue its exact rank, drives competition, and feeds the ads funnel.
On The List Miami: ZONA's nightlife briefing, a direct channel I own that turns the app's audience into recurring attention. Editorial takes, list rankings, and venue intel in the inbox every month.
The B2B side. Venues run their presence, events, and tables in one place. I built it and onboarded 25+ of them.
The supply side that fills the rooms. Promoters track their links, guest lists, and payouts in one place.
Audience, turned into revenue. An ad product that puts venues and brands in front of the right crowd at the right moment.
