Context

SipFlow is my own hydration app in development. Its starting point is simple: logging a drink should take almost no effort. Instead of entering a volume every time, you tap for each sip.

The task

Tracking can become a task in itself. I wanted to explore a lighter interaction, then give people a reason to return through a character with moods, small rituals and things to unlock.

Design decisions

1. Put the smallest action first.

   The core interaction is tap-per-sip. A first-drink calibration helps establish a personal estimate, while the main screen keeps daily progress close to the primary action.

2. Build a relationship with the character.

   The droplet has thirsty, happy and sleeping states. Petting, mini-games and visual customization turn the interface into a companion rather than a counter alone.

3. Make progression understandable.

   The work includes XP, levels, daily milestones, unlocks and rewards. I am iterating on how these connect so the reward is clear and the next step feels achievable.

4. Carry the interaction beyond the main screen.

   Widget concepts, reminders and calendar history extend the daily loop. SwiftUI implementation and on-device iteration help expose details that static mockups miss.

Context

metafora brings metaphors, creative exercises and practice materials into a mobile library. I work on the interface and visual identity, connecting the way people discover, organize and return to the content.

The task

A growing library needs more than a list of cards. People need a clear starting point, useful ways to browse and a quick route back to material they have already found.

Design decisions

1. Start with a topic.

   The home screen introduces practice topics such as anxiety, self-criticism, values and personal boundaries. A visible search field offers another route into the library.

2. Make returning easy.

   Recently opened cards bring useful material back into view. Collections and Favorites have their own places in the navigation, alongside Home, Library and Add.

3. Give the content room.

   Serif typography, warm ivory and muted topic colors establish an editorial visual direction. The layout separates navigation, topics and content cards while keeping the overall screen quiet.

Context

I led UX/UI design for Zivora, a migraine-tracking app, working directly with the product manager and development team. The work started with the MVP and continued as the product grew, covering user flows, interface design and the design system.

The task

The app brings together daily logs, migraine risk information, history and educational content. The design needed to give these different types of information a clear place in a mobile experience.

Design decisions

1. Map the full experience.

   The flow connects onboarding, the risk overview, daily logging, insights, history, education, integrations and settings.

2. Show the detail behind the overview.

   The risk-score interface brings individual biometric factors into view, including sleep, HRV, activity and readiness, alongside their contributions to the overall view.

3. Create a shared interface system.

   The UI work and design system give the product and development team reusable patterns beyond the first release.

Context

Eat No Solo is a German startup whose founder built a 50K-member Facebook community around a simple idea: nobody should have to eat alone. I worked directly with her as the product moved from a community into an app, supporting the launch across several European markets.

The task

The project needed a public face and a working product at the same time. The website had to explain the idea quickly and bring people to the app, while the iOS app had to make meeting strangers over food feel easy and safe.

Design decisions

1. Make the idea clear in one screen.

   The website leads with the core promise, meet now and don’t eat alone, and guides visitors straight to the App Store and Google Play.

2. Design for real-life meetups.

   In the iOS app, the flows focus on finding people and joining a meal with as few steps as possible, keeping the social moment in the center.

3. Keep one voice across every touchpoint.

   The website, pitch deck, social media content and printed flyers share one visual language, so the brand feels consistent online and offline.

Context

SynapSleep is a smart-bed project with a companion mobile interface. My design work explored how people could manage bed positions, climate, media and everyday routines from their phone.

The task

The product combines many different controls. The interface needed to make common actions easy to reach while giving more detailed settings a clear home.

Design decisions

1. Start with the bed and the current state.

   The main screen centers the bed, with a visual overview of its position and quick access to scenarios. Dedicated controls separate back, leg and lower-back adjustments.

2. Group controls around daily needs.

   Scenarios such as Sleep, Relaxation, Massage and Wake Up offer starting points for familiar routines. Separate areas organize climate, ventilation, thermal settings and media controls.

3. Keep one interaction language.

   The screens share dark surfaces, warm accents, sliders and clear active states. The concept also explores a health overview and Aliya, a voice-assistant interface with quick commands.

My contribution

Main dashboard and bed-position controls · Scenario selection and routine interfaces · Climate and multimedia screens · Health overview concept · Voice-assistant interface and shared UI patterns.

Context

Le Chef is an iOS app for people who cook and eat out. It brings recipes, restaurants and playful discovery into one place, with a single orange identity and a chef mascot at the center of the navigation.

The task

A food app can quickly turn into a database. Le Chef needed a fast way to find a dish, a home for your own recipes and a bit of play, so opening the app feels like an invitation rather than a search form.

Design decisions

1. Make search a shortcut.

   Voice and photo search sit as two large buttons above the categories, so finding a dish starts before typing. Cuisine tiles and a countries map offer a visual way in.

2. Give the mascot a job.

   The chef mascot anchors the bottom navigation as the central action, tying the identity to the interface instead of decorating it.

3. Leave room for chance.

   Spin the Wheel and Quiz turn the home screen into a small game for evenings when nobody knows what to cook.

4. One card for everything.

   Recipes, favorites and restaurants share one card layout with an image, a title and a single line of description, so the library and the restaurant guide read as one app.

Context

Seesaw is a prediction-market app from the US, where people place bets on whether an event will happen. The client asked for a redesign of the existing app, which showed one event per screen with a public-opinion seesaw at the bottom.

The task

The original showed a single question at a time and kept the odds small. The redesign had to let people browse many events, read the current odds at a glance and place a bet in a couple of taps.

Design decisions

1. Browse before you bet.

   The main screen opens with a profile header, topic chips and a grid of image cards, so events read like a feed instead of a single page.

2. Show the odds with the question.

   The event screen keeps the question, a short summary and a percentage ring together, with Buy Yes and Buy No as two clear actions.

3. Keep the stake simple.

   The bet screen has one amount field, the quick-stake chips carried over from the original and a single Buy button that shows the potential win.

4. One soft visual language.

   Rounded cards, a pale green profile block and a pill tab bar replace the flag-and-photo hero cards, giving the app a calmer, more product-like feel.
