Who I Am

Developer turned Security Researcher. I dabble in mechanism design, applied cryptography and AI. I have developed several open-source security tools, including FuzzCube, which offers distributed fuzzing capabilities with Kubernetes; Droid-FF, focused on Android fuzzing; and Diff-Droid, a dynamic instrumentation utility.

I have contributed to popular open-source projects like Mob-SF and co-founded the very first AI-Village at DEF CON. I have been invited to present these tools at international security conferences, including BlackHat and DEF CON.
