About

A designer who refused to stop at the handoff.

I started in UX/UI: flows, research, pixel-level interface work. The more I designed, the more I wanted to shape what actually reached people. So I learned to build.

Over the last months I went all in and designed and engineered entire products, alone and in production: voice input, real-time sync, auth, GDPR, push. That's the range I want to keep using, designing the product and building it together with a team.

Based in Munich. Working in German and English. Happiest with a hard interface problem and a blank file.

Design that can't ship isn't finished.

I don't hand off and hope. I take an idea through research, interface and production code until it works in someone's hands.

Taste is the differentiator.

Anyone can wire up a component. Knowing why a layout breathes, when motion earns its place and where to stop: that's the craft I obsess over.

AI is a power tool, not the work.

I build with Claude Code daily. It multiplies output, but judgement, structure and quality stay mine to own.

Selected work

Things I designed, and most of them I built.

A short arc: from building a product end to end, to high-stakes operational UX, back to where the craft began.

UNLOAD

Voice-first PWA for mental load

A voice-first app that makes invisible mental load visible, and lighter. You just talk, and it sorts tasks, appointments and shopping for two-person households automatically. Designed and built end to end in two months, solo, with Claude Code.

Product strategy, UX & full visual design, from blank canvas to shipped product
Whole frontend: ~11k lines, installable PWA, real-time sync between partners
Voice → Whisper → Claude → structured tasks, plus a fairness-aware dashboard
Auth, GDPR flows, push notifications, MFA. Production-grade, not a prototype

Dispatch System

Operations software for a Munich chauffeur service

The dispatch backbone for a premium chauffeur service in Munich: assigning drivers, rides and vehicles in real time under pressure. My main project as a product designer: turning a dense, high-stakes operational workflow into something dispatchers can read at a glance.

End-to-end UX: research, flows, information architecture for live dispatching and master data management
High-density UI that stays calm under load, built for speed and scannability
Design system for the operations team: states, edge cases, real-time feedback

Designed and built the whole system: Next.js frontend, Supabase data layer, auth and roles
Operations board that follows every shipment from booking request to invoicing, with live filters and status pipeline
Job initiation with margin tracking and approval workflow, plus tariff library, customers and suppliers

Foundations

Where the craft started

Finance App

2024

UX / UI Design · From my UX training

A personal finance app concept, one of my first end-to-end UX/UI projects, from user flows to a polished interface. Where I learned to think in systems.

Vocabulary App

2024

UX / UI Design · From my UX training

A language-learning app concept focused on habit and recall. Early work, included to show the starting line of the craft.

The craft

Same person. Both sides.

Most teams hand a design to someone else to build. I do both, so nothing is lost in translation. Hover the panel: the blueprint becomes the shipped product, right under your cursor.
