Hey there, I’m Xevi — a security researcher with a strong background in applied cryptography.

I currently work at Dusk, doing research and development in cryptographic protocols, especially in Zero-Knowledge Proofs. While I’ve spent the past few years working deeply on applied cryptography, my broader background has always been in system security — including vulnerability analysis, wireless network security, and offensive techniques.

I hold a PhD in Applied Cryptography from Pompeu Fabra University (UPF), where I was part of the WiSeCom group and also taught Cryptography and Security as an adjunct professor. My research focused on efficient Zero-Knowledge proving systems for constrained environments, with applications in areas such as mobile communications and IoT. You can find my thesis here.

Recently, I’ve been refocusing on hands-on security work — particularly vulnerability research, exploit development, and understanding how real-world systems break beyond their theoretical guarantees.

I’m especially interested in the intersection between cryptographic design and implementation-level security, where subtle assumptions often lead to practical vulnerabilities.
