I am pursuing a PhD in Cryptography at LIMOS and BeYs under the supervision of Pascal Lafourcade, Olivier Blazy, and Olivier Raynaud. My research focuses on applied cryptography, digital signatures, and lattice-based primitives.

I completed my undergraduate studies at Jerash University, Jordan (2018) and my MSc at ISIMA, France (2024).

Industry experience: I worked at BeYs, France (2023–2025) on the design and development of a data‑processing platform using Talend and Java. Previously, I was a software solution architect and backend developer (MySQL and Oracle) at ESKADENIA Software, Jordan (2018–2022). I worked on building telecom software including CRM, billing, and mediation systems.
