I'm Sebastian Seggewiss — a software engineer currently deep in offensive security: network pivoting, exploitation, and building small tools and labs for CTF-style practice.
Open-source is close to my heart, and these days most of that energy goes into breaking things safely in labs and building the tooling around it.

- seggewiss/double-pivot - Self-contained Proxmox VE network-pivoting lab (INE eJPT style) — DMZ to two hidden internal segments via chained pivots. https://seggewiss.github.io/double-pivot/ (1 week ago)
