„I'd rather have a search engine or a compiler on a deserted island than a game.“ - John Carmack

From design to implementation... not just an empty phrase. Good software design starts with a solid business process. From my experience, I can confirm that adequately defined processes are essential for quality results. At this point, it is important to work out the process and its solution with the client, considering requirements from both the technical as well as the design perspective. Especially with in-house development, it's a team project by the developer and the stakeholder, not just task-based implementation of assignments.

Sustainability and quality means...

...considering impact of prospective requirements. These may not be known by the client, or by the developer as well. Working as a team, rather than "solving tasks" is most important here, too. Sooner or later, software will reach a its legacy state. Sustainable software reaches it at a later date, especially if continuous improvements and refactoring are taken seriously. Just considering the quantity of "solved tasks" alone will reduce sustainability and quality on the long run.

The user is central

User experience is our term for understanding how users interact with software. Oftentimes, UX and technical demands develop over the course of the implementation process. Whether the user is a developer, an end user, or comes from another group of users does matter. My principle here is: Software should assist you with your work and should feel self-evident, without requiring heavy prerequisites or setup. Using the application (and especially the update and deployment process) should not feel like a Tamagotchi.

Novel & outside the box approaches

The standard solution which pops into mind at a glance is not necessarily the best. "Novel" isn't a contest of maximum creativity; neither is it the raw opposite of mainstream. It means observing requirements from an unprejudiced perspective and thinking about solutions without letting oneself get influenced by preexisting concepts. There are, indeed, requirements that are not meet by any standard solution.

architektenkreis is a website, where architects and students of architecture can present their projects. There are also options to purchase.

For this website, I have developed an individual content management system, which can handle multi-lingual texts, customers, bills and newsletters using the double opt-in method. The customer can present and describe their projects using text and images within the scope of the condition they paid for.


Literay is a raytracer that I developed in my apprenticeship and which I kept working on. The renderer supports lots of 3D objects and effects, such as lighting and shadows, anti-aliasing, reflections and textures. Since raytracing is a problem, that can be easily parallelized, the raytracer supports multithreading. The UI (the editor) is written in C# and WPF and the render engine itself is implemented in C++ for optimal performance.

The rendered scenes can be scripted using Lua. Since Lua is a runtime script and not static, you can also create more complex scenes programmatically.

3D mathematics is an exciting field for me, which is why I took this challenge.

In my apprenticeship in Euro-BBW Bitburg (Germany), there was a need for an issues tracker. Default solutions were never satisfying enough, because they couldn't handle all our requirements. That's when the development of "tick'it" started. I developed the issues tracker using PHP and I also provided a desktop helper tool, which I've written in C# using the DotNetBar UI framework.

Over time, all kinds of enhancements and improvement were made which became essential to our apprentice. Some of them include the team calendar, a knowledge database and other features that made our daily work easier.

tick'it is an individual issues tracker, which serves exactly our requirements. It has been further developed and became our home base without becoming bloated with improvisations and junk code.

Things that were written by hand, using Word and Excel or using different web apps are now managed by tick'it.

Image detection

Our customer hosts an online shop, which we have written a Windows 8 app for. This app displays product pictures on the Metro UI, but it should only display the relevant part instead of the entire picture.

So I developed an algorithm in C++ which detects the relevant part of the whole image. This was supposed to be done on the Windows 8 devices itself, so performance did play a role. The detection of an image should only take up to 100ms and should succeed in at least 80% of all cases.

The challenge was the vast variety of product images. Many of them had very heterogeneous backgrounds, like i.e. a wooden table. The position and the size of a displayed product varied a lot.

Musical floppy drives

This project started in my free time, when I started to experiment with the Arduino microcontroller. So I was figuring out if it was possible to utilize the motors of old floppy drives in order to make music with them. After all, everything that can vibrate with a certain frequency can make music.

The project was very interesting, because it is within the field of electrical engineering and it was a technological challenge.

So I did a lot of research and I came up with a working solution. I kept on working on it, making it better and better. Now, the Arduino can work with converted MIDI files and up to 6 channels. The device on the pictures works on its own, without the use of a computer.

Stack Overflow

Stack Overflow is one of the most popular communities amongst software developers. This is due to the unique concept of Q&A, which provides answers to user's questions and also creates an enormous knowledge database for developers searching for answers.

As a user, I like answering questions in order to contribute to the community and also to gain Reputation. A good reputation on Stack Overflow is helpful when it comes to asking questions myself. I also have moderator privileges, which are automatically granted based on reputation.


On my YouTube channel I'm presenting exclusive projects, which are interesting to viewers of the community. One of them are musical floppy drives (see also References). This project gained the biggest audience, although it was never my primary goal to generate views or subscribers. I'm also showing off other projects, including ones that come from the field of electrical engineering. is my project site where I'm showing off miscellaneous projects which I developed over the years. These are exclusively private projects which originated from my free time. Some of them include useful programs and tools, while others are research projects which I developed for purely educational purposes.

Some of these projects however, became increasingly popular, which established my online reputation.

Programming always used to be my primary hobby and still is. During years of career, I didn't lose interest in it! Individuals who made a career out of their passion are the most productive members of our society.

Microsoft Bounty Programs

During my research in security and computing, I am participating in Microsoft's Bounty Program. Microsoft pays bounties to white hackers when they find a vulnerability and manage to exploit it. The bounty goes up to $ 100.000. This way, Microsoft can fix issues before they can be misused.

27.03.2017: I have successfully managed to write an exploit that bypasses the User Account Control and escalate privileges silently. It works reliably on any Microsoft operating system up to Windows 10 Insider Preview. After this, I wrote up a whitepaper and submitted it to the bounty programs and to this date (May 2017) I got a confirmation of receipt, but the exploit is still functioning and is not patched. Due to coordinated vulnerability disclosure policies, I will not write any publications about the vulnerability.

May 2017: To this date, I have found 3 additional vulnerabilities and wrote exploits that impact the UAC in a comparable way. They work on different attack vectors and do not share a common vulnerability. Each of these exploits are not known to public and work on all Windows versions from 7 through 10 and x86 as well as x64. However, I did not submit to Microsoft, yet.

Future plans: There seems to be a lack of interest for UAC exploits. Therefore, I will focus my research on privilege escalation in full user-mode as well as sandbox escape.
