About Me

I believe openness helps us view complex problems from the right angle and distance, reducing them to reasonably simple engineering tasks. My strength is analytical and critical thinking across abstraction levels, from hardware and low-level OS work to operations scripting. I have worked in security research, Linux, Android, compilers, transpilers, debuggers, Ghidras, toolchains, networks, protocols (design and audit), DevOps. I have built agent-based tooling and started diving into the world of LLMs. I value Linux philosophy and aesthetics, but staying effective and pragmatic is even more important for me.
