SUMMARY

simon@cv:~

I've been building backend systems and managing infrastructure for 3+ years. I like working close to the metal: servers, VMs, deployment pipelines, the stuff that has to keep running. I also do reverse engineering — analyzing binaries, studying memory layout and protocol internals using Ghidra, IDA Pro, x64dbg, and Cheat Engine. I get uncomfortable when things are held together with duct tape, so I tend to fix them.
