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
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
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
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
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:

In my previous research, I encountered challenges related to extracting text from snapshots of newspaper articles using mobile phones. The primary issues I encountered when using user-friendly OCR software, such as Mac’s Preview, were as follows:
Handling Two-Column Text: Newspaper articles frequently employ a two-column format, which posed a significant challenge for accurate text extraction.
Persistent Hyphens: Hyphens located at the ends of lines remained embedded within the extracted text even after OCR and subsequent text correction, making it especially challenging when dealing with proper names.
For my current research, my objective is to identify a suitable OCR solution that can effectively address these challenges.

In rural areas, smaller events are typically advertised through flyers or newspaper articles, often in non-digital or unstructured formats. This presents the challenge of leveraging easily created snapshot photos, such as those taken with a smartphone, to convert these materials into structured event announcements.

Following the tutorials, getInitialProps is meant to work “on both server and the client”, which is totally correct.
Using server-side rendering (SSR) without any enhancements, this leads to a pwa, which is pre-baked for seo crawlers (content within html markup), but still loads content by the api, even if all data is within the rendered page already.
So be aware of implementing some client/server logic, when loading content by api is needed, and when it can be avoided.

In general, I am a genaralist. Project management, business management, website creation, design of complex software - it all feels like the same thing from different perspectives.
And somehow it is. It’s about collecting, manipulating, enriching, structuring, publishing and searching content or data.
That’s what I liked about content and document management. It is necessary to automate accounting and tax processes. It is the core of useful intranets as communication platforms. It is essential for task, problem and project management. It is even important in communicating with citizens for our local council.
It is all about content and data streams, flows, processes and channels.
With today’s technologies, I can build small solutions on my own while I’m on the train. Complex and large projects, which require an entire development team, are gladly led and managed by me. Manager and Product Owner I like to advise. I like to share my point of view with visionaries.
To realize amazing web solutions - whether small or really big - and bring them to life. This is my passion.

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 […].
So, now some new year projects are being completed. Number one: Download data from facebook and close my account. Task done.
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:
Well, there are some downsides like the question how to manage the content by editors, using dynamic and personalised content and so on.

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 built.io content stack, the concept felt quite familiar and I decided to have a second look at Podio - now as CMS for websites.
