Rockstar🎓
Top SchoolRobert Larsen is a security-focused software developer with 14+ years of experience specializing in reverse engineering, vulnerability research, and exploitation for Linux and embedded devices. Proficient in low-level languages and tooling—C/C++, Assembly (x86/ARM/MIPS), Python, Rust, IDA Pro, Ghidra and cross-compilation toolchains—he blends hands-on exploit development with practical systems engineering. At Forsvaret he continues applied security research after leading game and client/server development at CEGO, bringing production-grade discipline to offensive security work. He is an active contributor to pwntools, adding architecture-specific resolver improvements and test programs that aid exploit development across ARM and x86 platforms. Robert runs workshops on reversing, exploitation and shellcoding and maintains a technical blog, demonstrating a commitment to community teaching and reproducible research. He explicitly avoids web/frontend roles, preferring deep systems and embedded challenges.
