I design and build digital products that pay off.

For a pitch to Consorsbank, I supported the agency as UX design lead and, within two weeks, developed the concept for an adaptive banking app. It shows a customer's complete finances at a glance, from current accounts to ETFs and crypto, and adapts as their situation changes. I defined the visual and interaction language and designed the prototype at the center of the pitch. The agency won a 10+ year exclusive contract with Consorsbank.

TeamBank wanted to rebuild the website of easyCredit, its biggest product: fast and simple loans online. At USEEDS°, the agency I worked for at the time, I led a small team of researchers and designers that handled information architecture and UX, working alongside Strichpunkt and Ape Unit. Based on user research and customer feedback, we restructured how the product is explained within two months, simplified the sitemap and built responsive building blocks for the CMS. After the relaunch, new business more than doubled and service calls dropped significantly.

Signavio's products for process modeling, task management and process mining had grown up separately, each with its own look and patterns. As product design lead, I created Glucose, a shared design system that gives them one visual and interaction language as a suite. Starting from stakeholder interviews and a full UI inventory, I defined templates, base styles as design tokens and components with specs and usage guidelines, plus principles and governance for keeping it alive. Glucose covered about two thirds of all components and patterns across the products and became an internal product with management backing.

DQC builds a platform that monitors and improves enterprise data automatically: AI agents find errors and prepare fixes right where the data lives. In February 2026 I created its new website on my own, from concept and design to the finished code, built from reusable components for each part of the story. Instead of static screenshots, hand-coded animations on the platform page show the product at work, including an AI agent run that visitors can start themselves.

encoway, part of the Lenze group, makes software that helps manufacturers configure, price and quote complex products. Its new AI product P2M shows them which of their products are profitable and which are margin killers. I shaped the concept and design of its website together with another designer, who led the design, and built it on my own from scratch. The page tells its story through a scroll-synced image sequence in the background, a dot grid that follows the cursor and copy that highlights as you read.

Volkswagen wanted a carsharing service of its own to take on BMW and Mercedes. At the agency I worked for at the time, I led a small team through an eight-week project. Together with our research lead, I ran user interviews and service design, then led feature planning, visual design and prototyping of the app. After four rounds of design and user testing, the board was convinced: it gave the project the green light, and the service launched as WeShare.

DQC is a web app that companies connect to their data lakes to improve their data quality with AI. In 2024 I helped set up and design the first version. In 2026 I gave it a major visual refresh: modern design, clear hierarchy and strong data visualizations, plus proactive AI tools and an AI assistant that proposes fixes. It's the product behind the DQC website I built.

Future Living Berlin is a smart living pilot meant as a blueprint for more communities, with partners including smart, GSW, Schindler, Panasonic and Polarstern. In six weeks, a freelance art director and I designed how tenants arrive: a customer journey across digital and physical touchpoints, the content, and all assets. I led the service design, from research to digital design, and developed the pricing system for the smart fleetshare cars. The project won the 2021 Vision Award from the German Real Estate Society.

Airmeet is a startup whose platform runs online events, from meetups to conferences. As product design lead for the organizer side, I managed a team of UX designers and set the design direction for how events are set up. I also established how the company does user research, and wrote the design strategy the team aligns its work with. A single entry for login and signup significantly cut login errors and complaints.

McDry dry cabinets store moisture-sensitive electronics such as SMD reels, IC packages and circuit boards at about 1% relative humidity, so they don't crack during reflow soldering. For Seika Sangyo, which sells the cabinets in Europe, I built the website in German, English and French. Concept and design came together with a partner; implementation and setup were mine alone. Diagrams explain step by step how the damage happens, and a calculator shows what humidity can cost a company each year and how much of it could be saved.

Casanova AI is a dating assistant that suggests replies for ongoing chats. So people can try it before downloading anything, I built a simulator for the web onboarding: a staged chat with three messages, each scored live, with an AI reply one tap away. I also built the landing page and an internal portal for testing prompts. The apps themselves, which I designed, are a separate project.

With more than 300,000 employees, Deutsche Bahn is one of the largest employers in the world, and it wanted applying there to become much easier. At USEEDS°, I led the project as project and design lead: research with support staff, applicants, recruiters and hiring managers, the strategy that came out of it, and the information architecture and interaction design of the new careers portal. Based on the results, management committed to multi-year investments across the company.

Mister Spex is Europe's biggest online optician and a company run on performance marketing: designs and content are iterated and tested all the time. As UX Designer and later UX Co-Lead, I streamlined the journey from product list to order and supported the expansion across Europe. A virtual try-on raised retention and conversion by 12%, a mobile-first checkout brought about 10% more completed orders, and along the way I built a design system for the shop.

ProjectTogether is an incubator for social impact. It wanted a platform that matches social entrepreneurs with the right supporters, from foundations to CSR teams. In a six-week pro bono project, I led the design team as strategic design lead: research with founders and supporters, two design sprints with user tests, a validated product concept and a pitch deck. With that deck, ProjectTogether raised six- to seven-figure funding for the build and grew its team significantly.

Casanova AI reads a dating chat from a screenshot and suggests replies. For ArkApps, I conceived and designed the iOS and Android apps, which grew to include a photo studio, a practice arena with AI personas and a setup checklist, and passed 100,000 downloads on Google Play. I coordinated the iOS, Android and backend development, and I made the animations and shot and edited the videos myself. The code was written by the developers.

THE/STUDIO produces custom patches, apparel and promotional products, which customers design in an online configurator. I redesigned it completely: people now start with their idea, whether generated by AI, uploaded or just described, and only sign up once they have something worth saving. Every option shows what it adds to the total and the price per item, a live preview and the support chat stay in view, and the cart is finally separate from creating.

NOX Systems from Liechtenstein builds intrusion alarm and access control systems, and planning one used to take expert knowledge of panels, modules and power supplies. As a freelancer working directly for NOX, I designed a configurator that asks plain questions instead: new building or retrofit, type of facility, protection and security grade, then doors, zones and outputs. At the end it puts together a parts list, works out power supply, total load and battery backup live, and leads to a quote request.

Allgäu Pride e.V. brings queer visibility to a rural region, with CSDs in Kempten and Kaufbeuren, a summer-long pride program and an education project for schools. As a volunteer, I designed and built the association’s website as its central hub: event dates, background knowledge, donations and membership in one bright, welcoming place. The movement keeps growing: Kempten’s CSD went from over 1,400 participants at its 2025 debut to around 2,500 in 2026.

ChangeLock is an Android app that turns mindless phone checks into small good deeds. It logs every unlock, visualizes daily, weekly and monthly patterns against the average user, and pledges a cent per unlock to a charity of your choice instead of charging for yet another mindfulness subscription. I conceived, designed and built it end-to-end, privacy-first: no data ever leaves the device.

ALLBLACK is a fashion label for families who love dark, metal- and goth-inspired style: matching looks for parents, kids and babies that are hard to find anywhere else. I created the brand from the ground up, from the wordmark and collections like Mythical Beasts to the online shop that sells and ships made-to-order pieces across the US, EU and UK.

Anamno is a voice-first notes app for iPhone and Android. Hold the mic, say what’s on your mind, and AI turns it into a tidy note with title, tags and summary. Ask your notes anything and get answers backed by the source notes, while a background knowledge engine suggests connections and brings notes back when they matter. I conceived, designed and built it end-to-end as the first app of my mind-less brand. It is now in closed beta, with a web version for desktop.

TasteOS is an AI taste journal for iPhone and Android. Say or snap what you loved, whether a film, a book, a restaurant or a look, and it files the entry, keeps your own words and researches the details in the background. Instead of star ratings it writes a readable taste profile per list and suggests three picks at a time, each with the reason it fits, even across domains. I designed and built it as the second mind-less app, sharing one account with Anamno; it is now in closed beta.

Oh Poi! is an installable web app that teaches complete beginners poi spinning, from holding the poi to weaves and butterflies. Instead of videos, every move is generated by a custom 3D engine, so learners can slow it down, change the camera and see the paths as light trails. I designed and built it on my own as a spinner myself: 26 lessons across six levels, a spaced-repetition trainer with timer and metronome, and full offline use with no account or tracking.

Desktop Canvas is a menu-bar app for the Mac that paints fresh wallpapers from your own Desktop. It reads signals like file types, clutter, colors, names and recency, then turns them into an image across every display and Space. You choose from 19 styles: generative ones, styles built from your files, and AI art with your own API key. I conceived, designed and built it myself. It's signed and notarized by Apple, updates itself and runs locally: details about your files only leave your Mac if you pick the AI style.

Afterglow brings the MilkDrop light shows of the Winamp era to the TV. When YouTube plays music, a live visualization slides into a corner, and one press of OK on the remote turns it full screen. It analyzes the actual audio, tells music from talk and stays out of the way for everything else. I built it for my own living room and released it as open source: 24 GLSL visuals, no network access, installed by sideloading.

A Sony soundbar on HDMI eARC only shows its volume on Sony's own TVs. On any other TV, pressing volume changes the sound, but the screen shows no bar, no number and no mute indicator. Theatre Bar HUD fixes that for my own Xiaomi TV: it reads the soundbar's real level over HDMI-CEC and shows it in the TV's own volume HUD, over every app and HDMI input. It also remembers the volume per input. Open source, about 230 KB, no network access.
