Hi there!

I'm a computer scientist working in cybersecurity. I hold a master's degree from ETH Zürich (Switzerland) and an advanced studies certificate in cybersecurity from the Lucerne University of Applied Sciences (also Switzerland).

Within cybersecurity, I have experience across a range of topics like applied cryptography, X.509 public key infrastructures, cryptographic protocols such as TLS, secure boot processes, TPM 2.0 based machine identities, formal protocol analysis, machine learning, reverse engineering and web application penetration testing. Due to my fascination for the subject of cryptography, I run a YouTube channel, where I regularly upload videos with content related to cryptography and applications.

Besides cybersecurity, I have experience working as a quantitative developer across all financial asset classes. Moreover, from 2018 to 2020, I was the co-funder and CTO of HiPho, an online marketplace for hiring photographers in Switzerland.

Nowadays, together with my wife, I run Sukkus, a small but steadily growing nursery of succulents and decorative plant pot resales business.

Currently, I'm quite busy. Nevertheless, I'm generally always curious about new projects. So if you have ideas for small research projects (applied cryptography, formal methods for information security, machine learning for cybersecurity, policy and game theory based sharing of cyber threat intelligence), require a programming job to be done or are looking for consultancy around topics like algorithms, information and cybersecurity or business digitalization, then still please feel free to send me an
