Background & Experience
About.
Hi! I'm Kabir, a senior security engineer with a deep passion for highly technical pentesting and security research. I spent my time at Atlassian applying Application Security concepts to modern technologies including LLMs/AI, networks, AWS/GCP/Azure cloud platforms, SaaS integrations and in-house products and tooling. Now I work at Transgrid, securing Australia's largest electricity network and its OT environment. I play CTFs on the global stage with Emu Exploit, HashMob, and TheHackersCrew and produce music in my spare time.
