This is no portfolio. It is a showcase of projects and work I'm proud of.

I don't see the purpose in a full-blown portfolio with case studies neither I have the hours to write and code nor you want to spend the time reading.

But I get that one might get a feeling of how I tick and what I worked on. So, here are some icebreakers for when we meet.

MOCO

I help shape MOCO—a SaaS ERP for project-based businesses. Its focus on simplicity and effectiveness makes it a market leader in the German-speaking market, serving over 7,000 companies with 1 to 300 employees every day.

As product designer, I’m involved in most steps of product development: support, requirements, concepts, specs, testing, and launch.

MOCO 2.0

For my unsolicited application at MOCO, I refreshed the UI of three core views to create a modern, clean look (Figma link). It opened the door for my current role—though in retrospect, I’d add more UX-related ideas.

A desktop, tablet and smartphone mockup with screenshots of Jacobs personal website.

Personal Website

I regularly experiment with my personal website and its outgrowths, tweaking details and challenging what I have done before.

Recently, I enjoyed building a truly responsive, minimalistic experience with as few lines of code as possible.

No framework, no libaries–just pure HTML and CSS for full control and simplicity.

A desktop mockup with a screenshot of the DGM website.

DGM Website

At kultwerk, I managed a broad range of projects and website launches. The relaunch of the DGM website stands out: complex sitemap, strict accessibility requirements.

Besides my usual tasks as project manager, I took the lead in the concept phase and built a low-fidelity prototype in Axure before overseeing design, development, and launch.

A tablet mockup with a visualization of a metro map.

Metro Map

As a research assistant, I created a visualization of the spectrum of topics and expertise in my university research group. By utilizing the metro map metaphor, it was possible to connect three different research ‘lines’ and show the agility of all team members ‘operating’ them.

I sketched out the concept, refined the specific structure and content in multiple iterations with my colleagues, and designed the final version.

A smartphone and watch mockup with concept views of the Stay Fit app.

Stay Fit

Personally motivated concept to simplify fitness workouts by digitizing Kieser’s paper-based training documentation.

Instead of carrying around pen and paper, an Apple Watch app provides equipment settings, tracks training times and adjusts weights automatically based on the results. A companion smartphone app enables easy progress tracking and routine setup.

A tablet mockup with a screenshot of th Range InSight app, showing several charts and KPIs.

Range InSight

For my master thesis, I developed a modular web app as a ‘range companion’ for bus drivers—helping them build accurate mental models of range dynamics in electric buses.

Multiple widgets show key info on range and consumption, making insights transparent and easy to grasp. The prototype was tested in the field (read: public electric buses) and showed promising results.

A scattered stack of UNO cards, with vibrant colors and a modern design.

UNO Card Game

The UNO card game is a phenomenon. It's easy to learn and can bring a lot of fun, but its design is stuck in the past.

I created a new set with vibrant, easy-to-distinguish colors. Values in all corners allow fanning out cards left and right, and written numbers support faster recognition.

Add a few house rules, and you’re all set.
