Concept for a mobile business application that bundles data from various enterprise systems, evaluates it with AI and presents it as clear, prioritized insights.

The goal was to visualize SAP-like functional breadth in a much lighter, more intuitive interaction model — delivered as a compact 2–3-day exploration project.

A compact concept for a mobile app that lets people create and share challenges. A particular focus was on getting users to interact with the challenge assets — for example through playful micro-animations and lightweight rating elements.

The application was intended as a possible spin-off of an energy provider to open up new digital business areas.

Concept for an EV charging app that enables clear, smooth user guidance despite technical constraints — such as those imposed by payment providers or missing vehicle data.

The application was built for a large energy provider and later expanded into a white-label solution, including specific use cases for partners such as McDonald's.

A compact redesign reworked core elements of the existing trading interface — including market overviews, price data and table structures.

The focus was on a clearer information hierarchy and data that is faster to grasp, despite limited initial input and a tight timeline.

Concept for an energy management system that clearly maps energy flows, charge states and economic yield models.

The goal was a reduced, accessible UX that makes the complex performance and yield scenarios of large battery storage systems easy to understand.

With "Emma" we created a central marketplace where retailers and manufacturers can manage assortment, prices and orders in one place.

The platform replaces classic field-sales processes and maps the entire trading business in a structured, transparent way that is more efficient for both sides.

A comprehensive web application for companies that bundles shift planning, leave approvals and time tracking in one central system.

The challenge was to map the complex HR processes of very different industries so that teams can coordinate their everyday work in a structured, transparent and frictionless way.

At OURZ we developed a consumer app and a B2B platform that make the delivery routes and origin data of food visible along the entire value chain.

Beyond product development, the project also included branding, communication design and strategic consulting within the core team — from positioning to feature decisions for the app and platform.

For the German competitor to Google Analytics, core areas of the analytics platform were restructured and developed further. Complex reports, funnels and analysis processes were optimized through targeted UX mechanisms so they remain reliably usable despite technical constraints — for example around measurement logic or loading times.

In addition, my team and I handled the website's design, content creation and web development.

Naon started with a hardware gateway that could connect smart-home devices from different manufacturers. This approach was later moved entirely into a mobile app that controls devices and automates them with intelligent algorithms.

A central focus was lowering the barrier to entry into smart-home technology — through playful UI elements that at the same time created a strong brand identity.
