Product Designer — AI-powered consumer & B2B products

Kyiv, Ukraine · Remote imdennie.com linkedin.com/in/dennieo email

Summary

Product designer with 14+ years turning complex problems into simple, intelligent products — including nearly a decade at DraftKings designing large-scale, regulated consumer experiences: the bet slip and checkout, the web sportsbook and retail betting kiosks. Independently, a founder who has shipped three products from concept to launch — Numi (AI-powered nutrition, iOS), Tysha (baby sleep, iOS, 5.0 App Store rating) and Karta (QR ordering and payments for restaurants, web). I work across 0→1 product design, AI-powered experiences, complex product UX and design systems: defining the product, designing the experience, prototyping in code and shipping.

Experience

Product Designer · DraftKings — Sportsbook, web & native

2016 — Present

Design the bet slip and checkout — the flow every wager passes through — across web and the native app (rated 4.8 from 1.2M+ App Store ratings), for millions of monthly players in 25+ regulated US states, each with its own rules.
Simplified a complex multi-bet checkout — odds changes, limits, rejections and other edge states — into a flow that measurably improved bet-placement conversion.
Own the web sportsbook experience end to end: led a responsive web redesign, keep web at feature parity with native, and maintain the shared web component library and interaction patterns.
Started on the self-service betting kiosks for retail casino sportsbooks — designing within hardware and compliance constraints alongside hardware, operations and compliance teams — rolled out across multiple casinos and states.
Partner with product and engineering leads on the roadmap, review work across squads in design critiques, and drove cross-team initiatives spanning web and native.

Founder & Product Designer · Karta — QR ordering & payments, web

2026 — Present

Designing and building an end-to-end restaurant platform: one QR code lets guests browse, order, split and pay in their own language with no app install.
Owner back office with real-time floor plan, menu editor, analytics, POS integrations and auto-routed payment splits between kitchen, bar and staff tips.
Built the guest web app, owner dashboard, AI menu recommender and shared design system solo.

Founder & Product Designer · Numi — AI nutrition app (iOS)

2025 — Present

Designed and built an AI-powered nutrition tracker end-to-end — concept, positioning, UX, design system and a TestFlight beta launch.
Photo-based meal logging: snap a photo and AI analyzes calories, macros and micronutrients — replacing manual food logging entirely.
Designed a personal “Metabolic Fingerprint” insight engine plus fasting, weight and hydration tracking.

Founder & Product Designer · Tysha — baby-sleep app (iOS)

2026 — Present

Shipped a real-time white/pink/brown-noise generator for new parents — no loops, no accounts, no ads, fully offline. Holds a 5.0 rating on the App Store.
Designed around one-handed 3 a.m. use: layered sound mixer, saveable “Rooms”, fading sleep timer, Siri and Lock Screen control.

Founding Product Designer · Linc — cloud studio platform

2016 — 2018

First designer: established the brand, scalable design system and end-to-end UX for a studio platform-as-a-service for content creators.

Lead Product Designer · ShipShape Smart Homes — IoT

2016 — 2017

Owned product design end to end for a smart-home monitoring platform — UI/UX, design system, brand identity and mascot — while leading and mentoring a team of three designers.
Ran hands-on research, including field interviews and site visits into the crawlspaces where the sensors get installed, to ground the product in real-world conditions.
Partnered with engineering and stakeholders to ship the mobile app; drove agile delivery via sprint planning, scrums and retros.

Product Designer · Chatbox — customer-messaging SaaS

2014 — 2016

Designed and built the front-end UI for a channel-based team-messaging product — the pattern Slack would later define — working across management, sales and engineering to ship core features fast.
Design work contributed to securing investment and landing the first major customers.
