Summary
👤
Senior🎓
Top SchoolStefan Radu is a vulnerability researcher with eight years of hands-on experience in reverse engineering, low-level systems, and source-code auditing across C/C++/Java and Android ecosystems. He has worked on exploit development and microservice engineering, combining practical offensive security skills with production-grade software development at firms like CENSUS, Bitdefender, and now Exodus Intelligence. A strong algorithmic and formal-methods background (MSc in Security and Applied Logic) informs his methodical approach to finding subtle bugs in peculiar and open-source software. Based in Romania, he’s an active CTFer with the .hidden team, which sharpens his real-world exploit practice beyond corporate engagements. Outside security, he’s a hobbyist photographer and kendo athlete who still prefers vim—small pursuits that reflect a meticulous, disciplined mindset.
