“Tobis”, that’s the danish name for a number of fish species that are referred to as “Sand Eel” in English. Tobis is also my nickname.

Tobias Westergaard Kjeldsen is my name. I have always been very interested in computers, throughout my whole childhood to the present, and for me the computer is what the canvas is for a painter.

My interests includes a wide range of things; such as nature and wildlife, astronomy, taking photographs of landscapes and birds, doing programming and everything related to Unix-like systems. Much of my time is invested in any of these areas; admittedly mostly in programming. Another area I enjoy exploring and do frequently is any kind of reverse engineering of software; be it any tools related to instrumentation, decompiling, doing man-in-the-middle “attacks” or patching of binaries. It is fun to try and understand something that is closed-source and replicate that in free and open-source software.

I have touched many areas during my computer adventures–like general software development, web development, development on various mobile devices such as the Nintendo DS, Android, iOS and other flavors of embedded systems. I also have skills in the Unix-like domain; extensive experience and knowledge about the components of the system as well as maintenance/deployment aspects.

Current most ❤️ programming languages, SDKs and tools;

✅ Dart ✅ Flutter ✅ Frida

I’m curious by nature, a little wacky, and an eager self-learner.
