About

My personal character was shaped by my beloved family - back at home and in Military. I had the blessing to be educated on the values of good and taught professionally by the bests in the business. Being part of the intelligence corps of the IDF, serving in the two TOP elite technological units - 81 and 8200, was a groundbreaking experience. I had realised the most imaginary ideas in the field of offensive cybersecurity and vulnerability research, participating in many complex projects (on-and-off duty), some related to National Security. I am a `Silan` training program graduate and a former Officer in the Israeli Military. My goal in research is always one - find and be curious about the why. My fields of interest go beyond my profession to Finance, Diversity of Sports, Vegan lifestyle and Climate change. I’m here to connect with like-minded
