Hello!
I am a Java developer, both at work and at home. You will find me working not only on very detailed problems, like fixing a problem with native compilation, but also broader projects, like building libraries to be used by other developers.
I love open source and permissive licenses. Without them, most of my work would not exist. Therefore, most of my stuff is free too! Be sure to borrow stuff if you need it!
As already mentioned in the introduction, I know Java in and out. Generally I dig into everything I can find about it. This is not restricted to language features, but also the JVM itself (and others, GraalVM) and the ecosystem as a whole (all the libraries!).
Sometimes you want to do some low-level stuff, requiring talking to the OS itself. This is only possible if you can read and write C and have some knowledge about the things running behind the scenes.
I finally managed to tip my toes into rust. But there is still a long way to go!
I like file formats. They are extremely precise and picky, they are weird, they look completely different every time. I have worked on reverse-engineering a bit and it has been a challenge every time! Fun, but challenging. And infuriating.
My previous employer pushed to the cloud (AWS specifically) which meant to adapt. The environment is completely different and removes a lot of headache for basic functionality. It is extremely exciting to just use big building blocks and design large systems while only programming basic functions!
No need to waste time on something that already "just works"! And everything I got my hands on worked. Sometimes, some things are not obvious and fail silently but you get the hang of it.
My current employer uses Microsoft Azure. It is completely different there. Extremely nested, absurdly complicated and often stuff is outright broken... If you have any choice, do NOT use it.
I daily-drive Xubuntu and do a lot on the command line. Also I have a home server. And gaming on linux is definitly a thing!
Nowadays, it is essential to build systems where security is not just an afterhought. My goal is to always remind myself on "how this could be abused" when designing systems or writing code.
