since 2016

Digital consultant, managing director, software architect, lead developer, full stack developer, frontend developer and jack of all trades at MOTOR Digital.

MOTOR Digital realises digital solutions with a passion for quality.

Web profiles:


My typical positions in the past were at mid-size and large consulting companies and web software agencies, as well as national and international corporations and organisations.

In my projects I support the scoping, planning, conception, realisation and optimisation of web, app and software solutions through the whole product life cycle. My strength (and passion) is a technical deep dive in all of these roles.

There is often a great idea, a certain need or an unsolved problem. The challenge is to manage the transition towards a solidly planned project without losing the vision.

Within this process, I

  • create, validate, sharpen and consolidate business cases,
  • define the project scope,
  • carry out a requirement analysis,
  • set up the project including planning, prioritisation, definition of phase models and rollout plans,
  • carry out a risk analysis, and
  • evaluate and select technologies and software systems.

Every web and software solution needs specification, which has been carefully thought through. A consistent, solid and extendable concept, comprising all details will create the outstanding difference.

To create concepts and specifications, I

  • specify the requirements,
  • create the functional specifications including wireframes, click dummies and prototypes,
  • formulate acceptance criteria,
  • define the technical specifications including technology and system evaluation, and
  • design the software architecture.

Ideas and concepts are worthless, if they are not realised. Bringing the vision to life and creating an up and running solution is a key factor for generating business value.

To realise client solutions, I

  • carry out technical project management,
  • design the system and software architecture,
  • organise the realisation of prototypes, proof of concept development, complete realisation,
  • integrate the system into new or existing infrastructures e.g. ERP-, CRM-, DMS-integration
  • carry through quality assurance, test planning, automated tests, and
  • produce software documentation and training.

As requirements change all the time, the software solution should be adjusted to the actual needs. Finding out what is needed and what makes the solution even better is an ongoing process.

To measure and optimise, I

  • question, evaluate and refine the scope,
  • plan, develop a concept and realise within the context of existing systems and infrastructures,
  • measure and analyse existing systems for example on performance, conversion, usability, accessibility, code quality,
  • plan regression testing,
  • do user tracking and process monitoring, and
  • refactor or migrate ruinning systems to new technologies.

Technology Skills

The most important technology skill is to be open minded and able to learn new technologies. Because the world is turning - and in software business it's fast - there are always important experiences from the past and passionate skills from the present.

Technologies I love a try to place in projects, if they match the requirements:


  • HTML, semantic markup
  • CSS, transitions, animations
  • Javascript
  • Responsive
  • Performance
  • SVG, animations
  • REST
  • oAuth

Frameworks and Components:

  • SCSS/SASS, Bootstrap, Materials
  • NodeJS
  • GulpJS
  • GatsbyJS
  • Nunjucks
  • LoopBack
  • CouchDB
  • Elasticsearch/Searchkit
  • Docker

SaaS solutions:

  • Contentful
  • Podio
  • Cloudinary
  • Algolia
  • Netlify
  • AWS
  • Zapier

To summarise technology experiences from a timespan of 20 years is not possible at all - but the following lists will give an impression of my personal technical background.

  • Javascript, jQuery, AngularJS, React, Open Layers, …

boomerang - a no privacy solution

As looking for scheduling features for G Suite, one of the first hits might be boomerang. The feature set sounds great, but I wondered how they schedule the email sending technically.

Well, they do not explain it, so I did some research within their privacy policy. Let’s see …

Information We Collect Through Providing You With the Boomerang Service As you use the Boomerang Services, we may collect certain information about your Communications. We collect:

Now it starts:

the contents and header information from the Communications you send and receive through the service […] include at least the senders and recipient’s email address, subject line, message size, the date and time […], the system name and IP address […], […] geolocation data from your mobile device, […] information about events in your calendar, such as event titles, attendees, locations, and meeting times. responses from the recipients of your Communications […].

And hey, it’s perfectly expanding your privacy:

This information [..] allows us to analyze the content of your email […].

The real value of JAMstack

It’s not a secret that I am a fan of JAMstack websites. Like REST - which is basically using the core communication of HTTP - JAMstack is basically about using static websites - with some more around.

Static websites alway were great due to:

  • best possible server side loading performace,
  • best security, and
  • low complexity.

Well, there are some downsides like the question how to manage the content by editors, using dynamic and personalised content and so on.

Podio as CMS for a JAMstack website

In context of a collaboration tool evaluation for a client some years ago, I had first contact with Podio. And the most amazing aspect of Podio is the flexible data model. Together with all the other features, that makes Podio the perfect tool for internal data management.

Using Contentful in some web projects and trying out the content stack, the concept felt quite familiar and I decided to have a second look at Podio - now as CMS for websites.

An evaluation of NetlifyCMS

Netlify is doing a really great job with their hosting and build platform - specially for JAMstack addictive persons like me.

With NetlifyCMS they brought an idea to code, which for sure other developers had before as well - using git as content repository.

Using GulpJS as website generator

Usually “GulpJS is a toolkit for automating painful or time-consuming tasks in your development workflow”. And that’s what we are using gulp for most of the time. Specially the asynchronous approach combined with controlling the flow as parallel or serial tasks and the pipelining make gulp quite powerful.
