Passionate solution/software architect, developer, and thinker at heart. I know how to get things done. Can find work on my own. Going further than the job description.
I wrote C++ at the age of 13, no idea anymore when my actual first line of code was. That being nearly 24 years ago, things have accumulated. I've done small to big systems, embedded, backends, games, 3d, apps, mobile, web, the Kraken, you name it. Because coding alone wasn't enough, I have stumbled in many other areas for enrichment. Still a quick learner. New challenges get me excited, but it's less the actual coding anymore, even though I still get my hands dirty.
This is where I grew up as a professional programmer. How things communicate has always been my favorite topic and inspiration here comes from all areas. It's simply fun to do this well.
It has always been about data. Be it in the past with 3D Engines having different optimizations, but similar problems. Sometimes a lot, when you consider CUDA here. But its not just about speed.
Having also wandered into the Art School in Dresden, there was no way around not also getting my hands dirty with frontends. It has been fun, not something I need to do much anymore, but it helps me a lot in other endeavors.
It's a fun market. Those little things, that have hardly any power and you still need to save energy. But again, connecting them is where the fun is for me. Who wants the single master node, where your home can be hacked? Scary.
Having done all kinds of things helps a lot. Finding the right tools and evolvable architectures to solve problems efficiently and maintainable is my key focus. It's fun. You can make me use UML, but I think, we can find better ways to communicate.
