Profile

I am a senior freelance consultant with 20+ years of cross-disciplinary experience in building digital products.

I specialize in human-centered Interaction Design and scalable UI systems for web applications and other software.

I design and I code with equal expertise. That combination is not so common and makes a real difference on high-stakes projects, where design and development need to integrate tightly.

I am also experienced in leading people across a range of contexts: freelance projects, permanent roles, workshops, and the classes I teach.

In all of these situations, I encourage sharing knowledge — as the best results come from building on each other’s strengths.

Selected work experience

Design Coach

Viergrad GmbH Freelance May 2024—today

Coaching Mentoring Design Education

I support the digital agency Viergrad with training and coaching on design. I regularly run workshops for the entire team and I advise their designer on day-to-day design decisions. This includes design reviews, short training sessions, and coaching for professional and personal development.
Lecturer & Teacher, Interaction Design

S4G School4Games Freelance May 2013—today

Teaching Mentoring Curriculum Design

I developed a three-semester lecture series on the fundamentals of Interaction Design for the Berlin-based School4Games . The program teaches design principles, their connection to human behaviour, and their roots in cognitive psychology, including hands-on exercises exploring practical methods and frameworks such as Design Thinking.
Designer & Developer

Valuya Freelance Feb 2024—May 2025

Branding UI/UX Design Web Development

The FinTech startup had built a fully functional prototype for trading digital assets. My role was comprehensive — I named the product, designed the logo, took on the entire UI/UX design, and developed the front-end.

Thanks to close collaboration with the founder, who was also responsible for back-end development, and my cross-disciplinary skills, we were able to build a highly complex product, structurally ready for fast scaling, in a relatively short time and with minimal overhead.
Consultant, Design Education

Experience One Freelance Apr 2023—Jul 2023

Consulting Moderation Education Corporate Culture

To promote professional development at the digital agency Experience One , I worked with the team to develop a series of informal formats for collaborative learning. We tested several approaches and gathered feedback through surveys.

The initiative was very well received, giving the company a straightforward and motivating way to foster knowledge sharing and professional growth across the team.
Consultant, Design Systems

Adjust Freelance Nov 2019—Mar 2021

Design Systems Consulting Strategy UX Design UI Design UI Engineering

Within a very short time, Adjust grew from a start-up to a global industry leader. The company had accumulated software developed in-house and through acquisitions, resulting in significant inconsistencies across design and functionality.

I led the project to develop a comprehensive design system. We built a dedicated team, created a unified design language, developed UI components and produced detailed documentation. I also ran workshops and training sessions to equip the team to maintain and expand the system.

The result is a unified software suite delivering a more consistent user experience, consolidated internal knowledge, and scalable architecture and processes — which have significantly accelerated and simplified Adjust’s product development.
Team Lead

Yoshino.digital Employed Oct 2017—Sep 2019
Leadership Team-Building Design Direction Web Development Mentoring

After its founding, Yoshino needed to establish a location in Berlin. I was responsible for assembling a small cross-functional team and setting up the office.

My role encompassed team management, design and development direction for UI/UX and front-end work, and individual mentoring. Together we successfully completed numerous complex projects for clients across various industries.
- eGym
  
  We conceived, designed, and developed a large corporate website for eGym, a manufacturer of connected premium gym equipment.
- Lynx
  
  We advised the in-house design team of Amsterdam-based online broker Lynx on the redesign of their international corporate website and the associated development of an accompanying design system.
- Aristander
  
  We developed the brand and product design for Aristander, a price prediction start-up built on machine-learning.
- YOI
  
  To produce the many microsites we built, we needed a flexible, framework-agnostic front-end system. I built a well-documented system , anticipating concepts that are now taken for granted, such as CSS utility classes and JavaScript interactions driven by a simple HTML attribute API.
Teacher, Programming for Kids

Haba Digitalwerkstatt Freelance Nov 2016—Feb 2017

Teaching Visual Programming Curriculum Design

I developed an introductory course for Scratch (a visual programming language for children), for the Berlin-based »Digitalwerkstatt«, run by the renowned German toy manufacturer Haba .

Working in small groups, children from grades one to four created their own games using simple modules I had developed beforehand (button controls, collision detection, and similar building blocks). The playful process enabled the children to learn the basics of programming — at their own pace and with direct reference to their own projects.
Consultant, Web Development

IBM iX DACH (formerly Aperto) Freelance Apr 2015—May 2015

Consulting Design Systems Web Tooling UI Engineering

I assisted IBM iX (formerly Aperto) in evaluating the technical setup of a large customer project, focusing on front-end tooling and the optimization of the CSS architecture.
Designer & Product Developer

Able Labs Freelance 2014

Concept Direction UI/UX Design Product Development Research

At the peak of the 2010s VR/AR hype, shortly after the Google Glass release, a colleague and I started wondering: could Spatial Computing and Augmented Reality be combined to create something useful for everyday life that actually delivered meaningful benefit to its users?

We secured modest private funding and I put together a small independent team of developers and designers to build a prototype. The concept was simple but innovative: the smartphone camera recognises key surfaces in the room — say, a page in a magazine — and activates interactive content as soon as the device is placed on it. A small interactive island within otherwise static content.

We produced a functional technical prototype and an elaborate concept video . The endeavour did not result in a real product, however, it was a fascinating exploration nonetheless.
Frontend Developer

KKLD* Freelance Oct 2013—Jun 2014

Web Design Web Development JavaScript HTML CSS

I built the website for the digital agency KKLD* in close collaboration with their design team. The result was a fast, fully responsive, and easy-to-maintain static website which did its job for more than ten years.
Consultant, Web Development

IBM iX DACH (formerly Aperto) Freelance Oct 2013—Jun 2014

Web Design Web Development JavaScript HTML CSS

I consulted for IBM iX (formerly Aperto) on a Volkswagen project: a multimedia website with numerous interactive features, embedded videos, and page transitions that had previously only been possible with Flash .

Drawing on my experience with a similar project for DDB, I was able to guide the team through the planning and implementation of a technically demanding design.
Designer & Developer

KircherBurkhardt GmbH Freelance Mar 2012—Jul 2012

JavaScript UX Design UI Design Web Design HTML CSS

I assisted the agency KircherBurkhardt in developing mobile web apps for the German financial newspapers Handelsblatt and Wirtschaftswoche. The timeframe was tight and required us to rethink the design workflow. Working closely with the designers, we shifted from producing static design assets in Photoshop to designing directly in the browser.

This setup eliminated the need for an interactive prototype, accelerated the process, and allowed the customer to view the current status of implementation at any time. At launch, we had built a state-of-the-art web app for phones and tablets with extensive theming architecture — producing app.handelsblatt and app.wiwo — with a user experience similar to native smartphone apps at the time.
Web Developer

DDB Germany Freelance Aug 2011—Oct 2011

Custom Framework Development JavaScript HTML CSS

DDB Berlin designed a website for the new VW Beetle with a strong focus on interactive storytelling, using virtually every cutting-edge web technology available at the time. The scroll-driven experience even allowed users to navigate the desktop site via swipe gestures on a companion smartphone app.

I was responsible for the technical implementation, and together with a freelance colleague developed a complex framework to drive video and parallax animations through scrolling.

The site was technically impressive, set new standards for interactive storytelling on the web, and won a few major design awards.
UI Designer

MOTOR-TALK.de Freelance May 2011—Jul 2011

UX Design UI Design

I designed the first iPhone app for Motor Talk, Europe’s largest online car community. Working closely with the iOS developer, we created an app with great attention to detail and an elaborate skeuomorphic design typical of the time.
Developer & Designer

Team Global (formerly Team Europe) Freelance May 2011—Jul 2011

Design System HTML CSS JavaScript PHP UX Design UI Design

The company — then known as Team Europe — commissioned me to optimize a front-end project for significant scale. The result was a white-label business directory with an integrated editorial section that gave listed companies a platform to publish content, driving strong Google search rankings.

I worked on the theming system that enabled the rapid production of numerous verticals with minimal effort, helping the start-up establish a strong market position.
Web Designer & Developer

Juvalis Freelance May 2009—Jan 2015

Design System HTML CSS JavaScript PHP UX Design UI Design

I designed the entire online shop and programmed the front end for Juvalis, one of Germany’s leading online pharmacies at the time. After launch, I oversaw further development over an extended period.
Art Director Digital

gosub communications GmbH Freelance Apr 2007—Apr 2009
UI Design UX Design Web Design Frontend Development Corporate Design

After graduating, I went to work for Gosub Communications . The company was among Berlin’s leading digital agencies at the time and specialized in complex, interactive digital experiences.

I worked across numerous projects for clients including ARD, ZDF, SAT1, SF (now SRF), MTV, Nickelodeon, BMW, Universal Music, and Ferrero, among others.

Those were pivotal years for web design: with the advent of the iPhone, Flash was on the decline, and my early specialization in native web standards (HTML, CSS, JS) significantly broadened the agency’s skill set.
- Ferrero
  
  I was the design director for the Hanuta website — an interactive experience inside the fictive Hazelwood Forest, a brand universe inspired by Robin Hood. The result was part game, part website: an explorable landscape with multiple levels, each containing exploration tasks or mini-games. A leaderboard with an avatar editor rounded off the experience.
- Schweizer Fernsehen
  
  I was the leading web developer for Schweizer Fernsehen’s children’s programming website. At its core was a child-friendly community, a media library with a comment function, and various small Flash games.
  
  The visually rich design with analogue elements — torn paper edges, hand-drawn squiggly lines, and a distinct colour scheme for each channel — posed a major technical challenge for the time. The end result was a richly designed site with fast loading times and semantic HTML.
Graphic Designer

Freelance Jan 2003—Mar 2007

Graphic Design Corporate Design Web Design Web Development

While studying, I worked as a freelance graphic and web designer. I designed logos, flyers, and posters, and built websites for small local businesses.
