I build AI systems and I break things to make them safer.

About Me

AI engineer and security researcher based in Reykjavík, Iceland. Born and raised in Lagos, Nigeria, I moved to Iceland in 2023 and earned an MSc in Computer Science at the University of Iceland. Before that I spent five years working across AI and cybersecurity.

My work sits on both sides of the attack and defense line: I fine-tune and deploy language models, and I find and responsibly disclose vulnerabilities in real systems.
