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.

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

  • define phase models and quality gates for realisation and rollout,
  • carry out technical project management,
  • 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
  • plan usability tests.

Google Analytics without Cookies

I haven’t heard about this before, but it is possible by default to use Google Analytics without cookies. Well, Google does not recommend this, but it is working just fine.

To make it work, some issues have to be solved:

  • deactivate the cookie storage
  • implement an alternative for the user id

BrowserStack screenshot service uses emulators

In my personal roadmap on automated tests integrated in a countious deployment strategy, my first phase was setting up screenshot regression tests. Within this phase I wanted to extend the tests from a simple setting at GhostInspector to cross device/browser tests. So I’ve got a subscription at BrowserStack with the aim to trigger the screenshot API an generate all browser screenshots automatically.

But on this way I recognizes 1) a lot of timeouts, 2) different browser display behaviours than on real devices, and 3) stange effects with backgrounds and fixed/sticky elements on longer pages. The first issue makes automation impossible, because you cannot trust on reliability. The second issue made the test results not usable - if the screenshot on android 4.4 has no main menu, a alarm rings in the head of a tester, but with not using emulators, everything is fine.

Jekyll as frontend development tool

I am used to enforce a strict separation of frontend and backend development in web projects. Major reason is the amount of effort which is needed for quality assurance for frontends and the risks of changing frontend details while implementing backend logic. So with this separation, projects got a quality gate for the frontend independent of the backend and process complexity.

As I am using Jekyll quite a time for my own website and some smaller client project, I learned to love the easiness while utilising strong features at the same time. The gracious combination of features like - a template engine for separating content from layout markup while use things like if, else, loops and more - include templates with parameters - scss built in - having static html at the end makes Jekyll quite an easy and strong tool.

So I started to use it for building static web frontends as prototype phase before going into cms or shop implementation.

Next journalism?

In a meeting at Sternwald we asked who has a newspaper subscription - and there were only a few. The hypothesis is, that the format todays generation likes to consume, does not exist yet.

I thought about that: I like to read my local newspaper, because real local news are not available in the web in a proper format. Additionally I like to read (and listen) to some specialised blogs and podcasts like

TYPO3 with Nginx using RealURL and Static File Cache

While using the Docker TYPO3 Boilerplate and moving to a hoster who likes Nginx more than Apache, I gave Nginx a try for a TYPO3 installation.

So as expected nothing really failed. The only challenge was to configure Nginx for RealURL (quite easy) and Static File Cache (a little more advanced, because the given templates are not all complete).

Experiences with the Docker TYPO3 Boilerplate

A classical situation: Caused by some misconfiguration on a server a friends website got down. To solve the problem in long-term we decided to move the TYPO3 installation to a specialised and managed hosting company.

But for moving the website we had to do an update of TYPO3 as well and I had the need to setup a development environment. My former setup on my local machine was gone through several OS updates and so on. And to make it even harden, we needed two different setups - one for the old system and one for the updated TYPO3 with newer PHP and MySQL versions.

So as I am using docker anyway at othe projects, this seemed the best way - even if I was afraid to waste much time for setting up a clean docker environment.

Continous integration - first steps with Distelli

It’s like a buzz word: Continous Integration.

All talk about countinous integration, high frequent releases and automated tests. But in regular business there is no one really doing it. At software and web development companies these practices are more a kind of vision than reality. For sure they are companies doing it and generate benefits for their business modell. But my guess is, that most who use a continious integration process have a digital business model and the DNA of the company supports a straight strategy. As software developer for non digital companies it’s mostly a dream nobody likes to pay for.

As I am not a patient human and my experiences told me to know it better on my own, I set myself the goal to evaluate the technologies in depth and introduce them to my future projects as technical project manager.


For an easy start I looked out for a SaaS platform for continous integration and found Distelli as one of the well known. And they are capable of using docker builds and a pipelining approach.

ecommerce evolution leads to something like moltin

In several projects I could watch the evolution of ecommerce platforms in a way like that:

  • start by using a shop system like magento or shopware
  • using and extending the api
  • integrate third party apis
  • integrate rich clients and non-web fromtends like apps
  • thinking about rafactoring
  • creating an ecommerce api layer with the goal of a service architecture and finally a baas system

So, that’s what the guys at moltin realised as well - so they deliver the important essentials for ecommerce solutions: api based core funtionality and a default management backend. No one likes to have more than that.
