I'm a cybersecurity engineer and software developer based in Switzerland, with a Master's specialization in cybersecurity and a strong foundation in software engineering.

My technical focus lies at the intersection of OT security, zero trust architecture, and applied cryptography. For my Master's thesis, I designed and deployed a zero trust network for a smart power grid substation using real Siemens and Omicron hardware — developing an original encapsulation approach to bring legacy field devices into a modern security model.

On the software side, I co-founded a tech startup where I served as sole architect and engineer of multiple production mobile applications, including one that reached 10,000+ downloads and CHF 200'000 revenue. I've owned everything from backend design and CI/CD pipelines to security infrastructure and team mentorship.

I'm currently seeking my first professional role in cybersecurity — ideally in OT/ICS security, penetration testing, or security engineering — and am actively looking at opportunities in Singapore and across Europe. I'm open to visa sponsorship and ready to relocate.
