For a current project, I need to read data from an API, transform and push it to an AWS S3 bucket. Normally I would consider to use a standard programming language for that because there is no “magic” involved. However, one of the requirements is to use Benthos, a tool for “Fancy stream processing made … read more …
Back in 2010, when I started studying computer science, the very first thing that I have asked myself was: who is responsible for protecting my data? This was a start of a new journey for me. On the one hand, I was learning a lot of new things, such as OOP, databases, distributed systems (today … read more …
In 2019 I wrote about a MySQL 5.7 migration at Check24. While it is very exciting when working on new features, it is also a good thing to think about the architecture and use modern frameworks and libraries. Working on the architecture provides also the opportunity to improve source code quality and introduce quick wins. … read more …
In this post, I want to address scalable system design and how to grow a system while it’s user base grows. Because talking only about the theory can become boring very quickly, I want to discuss this topic on a practical example. Before I start with the design itself, keep in mind that there is … read more …

During the Covid-19 pandemic I decided to set up a server at home for different use cases. The server, that I very creatively called server1, should be a central place to build a file archive, a git server (an alternative for GitHub projects not intended for the web), a testing server for new applications (such … read more …
This blog post is about Computer Science and my current skills in it. While I started to work on side projects (such as PHPAlgorithms, Keestash or Unread News), I have neglected my theoretical knowledge (and the practice following the theory). I want to brush them up a little and utilize this blog post as a … read more …
One thing I like at my current employer Check24 is the variety in topics and the trust in me to master them. This motivates me to take my work very serious, but also gives me a lot of responsibility since our products represent Germany’s biggest platform for comparing almost everything. But Check24 is not only … read more …
Last year, I announced PHPAlgorithms. Since then, I worked a lot on this repository as part of my personal learning progress on Algorithms and Datastructures. Now, I am proud to announce that we have reached our first milestone – version 1.0.0. With the support of the community, we fixed remaining issues and made this release … read more …
The beginning of this week was a little bit more action packed than planned. After a couple of weeks of coding and intensive testing (seriously!), @rauchbar and me were of the opinion that the feature is production ready and could be deployed. But well, shit happens when you least expect it. PHP Stacktrace As developers, … read more …
