Hi, I’m Dennie — I turn complex problems into simple, intelligent products.

A product designer with 14+ years across web, mobile and emerging tech — working where product strategy, UX and technology meet. These days I build AI-powered products, moving fast from concept to prototype to something people actually use. Currently designing large-scale consumer experiences at DraftKings.

My products

Products I’ve designed, built & shipped.

Three products I took from idea to launch — two on the App Store and one full web platform — owning the concept, the experience and the design system end-to-end. Below them, a track record of work where I owned the design.

Numi

Food clarity, redesigned.
AI nutrition app · iOS In beta · TestFlight

My own product — an AI-powered nutrition tracker for iPhone that kills manual food logging. Snap a photo and it instantly analyzes the meal — calories, macros and micronutrients — while building a personal “Metabolic Fingerprint” for context-aware guidance. I designed and built it end-to-end: concept and positioning, the photo-logging flow, fasting, weight and hydration tracking, the insights engine, and a clean design system tying it all together.

Tysha

White noise for the 3 a.m. shift.
Baby-sleep app · iOS Live on the App Store

A white-noise app for new parents and those late-night wake-ups. It generates real-time white, pink and brown noise you can mix and save — no loops, no accounts, no internet, no ads. I designed and built it end-to-end around one-handed, instant playback: a layered sound mixer, saveable “Rooms”, a gentle fading sleep timer, Siri control and a Lock Screen timer — all fully offline.

Karta

Scan, eat, pay, go.
QR ordering & payments · Web platform Live · new in 2026

My newest product — one QR code for a whole restaurant. Guests scan the sticker on their table to browse the menu, order, split and pay in their own language, with no app to install. Behind it sits a full back office: real-time floor plan, menu editor, analytics, auto-routed payment splits between kitchen, bar and tips, and an AI “help me choose” waiter. I designed and built the whole system end-to-end — the guest web app, the owner dashboard and the design system tying them together.

Selected track record

Earlier products where I owned the design — research and flows through design systems and shipped, polished UI.

Linc

Founding Product Designer

A studio platform-as-a-service for content creators. I joined from day one — building the scalable design system and end-to-end UX, defining personas and flows, and iterating from user feedback alongside engineering.

MyGoTrainer

Lead Product Designer · UX/UI

An iOS marketplace connecting clients, trainers and facilities. I owned the entire UI and UX across all three roles — personas, usage scenarios, wireframes, screen flows and final mockups.

  • iOS App
  • Marketplace
  • End-to-end UI

Shipshape

Lead Product Designer

Smart-home monitoring that catches household problems before they get expensive. I led a team of three and owned design end to end — UI/UX, the design system, the brand and its mascot. I did the research firsthand — running user interviews and climbing into the crawlspaces where the sensors get installed — then shipped the mobile app alongside engineering and stakeholders.

Chatbox

Product Designer

Where my product-design career began. I designed and built the front-end UI for a channel-based team-messaging product — years before that pattern became the category Slack would define. Working shoulder-to-shoulder with engineers, sales and leadership, I shipped core features fast — work that helped secure investment and land the first major customers.

  • Team messaging

E-commerce

Senior Product Designer · Design Ops

Helped scale a small agency into a full e-commerce brand, designing experiences for major retail clients. I established the design practices and delivery flows, and mentored the junior designers on the team.

Kind words

What people I’ve worked with say.

From LinkedIn recommendations by founders and leaders I’ve built products with.

Denys is an exceptional UI/UX designer and Product Owner with a great sense of feature design… He draws a clear distinction between something looking great vs. something being a great user experience. I have no reservations about recommending Denys as a part of any team that wants to take its UI/UX talent to the next level.
Kira Rudik
Member of Parliament, Ukraine · managed Dennie directly
Denys is a very strong UI/UX designer with transferrable skills in HTML, CSS and light JavaScript. He’s very easy to work with, has a great attitude, has strong intuition about feature design, and is a pleasure to be around. He’s hard working, strongly self-motivated, and quick to learn.
Phil Gordon
CEO & Founder, Prompt.io · managed Dennie directly
Dennie is a hard-working, grind-it-out, get-the-job-done UI/UX designer… He uses his strong communication skills and obsessive focus on product to rapidly develop high-quality products. I truly enjoyed working with Dennie and would gladly endorse him as a UI/UX designer.
Dane McLeod
Product builder · 3× founder, FinTech & SaaS · managed Dennie directly
Denys is a detail-oriented and forward-thinking designer. He deeply cares about his work, always asks the right questions and is a great team player. He always met deadlines, was well organized and was an integral part of the success of all the projects he worked on.
Adam Brazg
CEO, Bilberrry · managed Dennie directly
Dennie managed a team that developed exceptional work product with remarkably little direction or oversight. He took responsibility for understanding the product vision… Dennie quickly learned whatever was required to accomplish the job and maintained flexibility to change plans when needed.
Alexander Linn
Founder & CEO, Shipshape AI · managed Dennie directly
He is a very meticulous, well-organized, and disciplined Program Manager. Dennie made it easy to coordinate the efforts of a large R&D team… He managed deliverables and worked at all hours to make sure that projects move forward and milestones were met. Highly recommended.

About

Where design, AI & technology meet.

I’m a product designer with 14+ years designing and shipping digital products across web, mobile and emerging tech. My work sits at the intersection of product strategy, user experience and technology — turning complex problems into simple, intuitive experiences while balancing user needs, business goals and technical constraints.

At DraftKings, I design large-scale consumer experiences in a highly regulated, fast-moving environment — where usability, performance and consistency directly shape engagement and business outcomes.

Beyond the day-to-day, I actively build and experiment with AI-powered products — exploring how modern language models, intelligent systems and rapid-prototyping workflows can accelerate development and unlock entirely new experiences. My own products — Numi (AI nutrition), Tysha (baby-sleep sounds) and Karta (QR ordering & payments for restaurants) — came out of exactly that: concept to prototype to shipped. I’m drawn to work where product design, AI and innovation come together to solve meaningful problems — and make products that feel both useful and delightful.
