Hi! I am David, Product Manager, UX Designer, Coder and Founder.

For more than 15 years, I create digital online services such as (mobile) web applications and responsive websites. I love to work in teams with the vision to build services that add true value and provide a stunning user experience. Through several projects, my studies and founding fotograf.de, I gained extensive technical and analytical expertise that helps me to combine requirements and feasibility in a holistic way. 

How I can support you

Ideation

Working in cross-functional teams to create innovative concepts and digital strategies is one of the things I enjoy most. In creative sessions, we brainstorm, draw on whiteboards, do research and talk to customers – to generate ideas, how to gather information in a meaningful way and making it accessible via intuitive interfaces, always facing the needs of the users.

UI / UX Design

This step is about transforming the sketches into visual screen designs to share them with the stakeholders. I always try to combine simplicity and state-of-the-art design. It usually makes sense to have a clickable prototype, especially when it is about the user interaction with the interface. Tools of my choice: Adobe XD and Sketch.

Usability

During the years, I performed hundreds of user tests. So I will provide you my collection of usability best practices. But of course we should also schedule individual usability tests! Why? Because “you can never be sure until it is tested”.

Prototyping

Once we have an advanced idea, I can support you building a working prototype – using PHP, MySQL, JS, HTML, CSS and Frameworks like Bootstrap and jQuery.

Product Management

I worked as a product manager in a scrum team for several years. So I can also help you cut big projects into smaller pieces, formulate tickets for developers or play planning poker to estimate the effort.

Analytics

After the rollout, you probably want to know the results. I usually integrate Google Analytics, but I can also provide you with useful MySQL queries for custom reports. More tools I used: Crazyegg, Metabase and Fullstory.

In 2019 I am taking new freelance jobs – in Berlin or worldwide. Interested?

Recent project

fotograf.de logo

The last 7 years, I co-founded and worked for fotograf.de. It is a fantastic SaaS online shop system and website building kit for photographers with tons of features. By this time, it supports thousands of photographers to sell photos online to their clients. Quite a few of them are generating their main income through the platform. Currently, fotograf.de is operating mainly in Germany, United Kingdom, USA, France, Austria. Back then, we were 4 founders working on the idea – now fotograf.de has over 50 employees. During the years, I worked on many projects inside of fotograf.de – always focussed on the product – solving problems with innovative ideas and providing a remarkable User Experience. To give you an idea of it and what we did, I published some articles in the Blog.

Former clients

Before working full-time for fotograf.de, I co-founded the Solutica GmbH, an agency specialized on extensive Web Applications and Sites – and awesome clients.
