About Me
I'm Johannes, a backend developer at 
working on scalable and maintainable storage orchestration. I build
systems that are meant to run reliably, be understandable later, and survive
real production constraints.
This site collects my work and notes around backend engineering, HPC, low-level programming, embedded systems, virtualization, and containerization. Some of it is writing, some of it is documentation, some of it is experiments that turned out useful enough to publish.
Most of this comes from hands-on work with production systems, homelabs, and open source. I care about simple designs, clear trade-offs, and explanations that don't hide complexity behind buzzwords.
