Peter Marki
Software Developer -> AppSec Engineer
Motivation
With the rapid rise of LLMs, we are now producing more code than ever, faster than ever. While the feats that are possible today are truly impressive, it raises an even more interesting problem: more software also means more vulnerabilities. Add to that the potential for AI agents themselves to become defensive or even malicious actors, and you have a fascinating landscape in an industry that's going to get ever more relevant. This is exactly the type of complex, multi-dimensional problem solving that drives me and that brought me to IT. This is why I decided that it's time for the next challenge and pursue a career in cybersecurity.
