Senior Rust / Systems / Applied-Cryptography Engineer · Barcelona, remote (CET)
20+ years building performance- and security-critical systems in C/C++ and, for the last 8+, in production Rust. I'm usually the person who introduces Rust into a team and architects the core platform others build on — threat-detection backends processing millions of events, SOAR security platforms, distributed browser/peer-orchestration systems. PhD in cryptography (IACR-published), with real applied work: digital signatures, PKI/HSM, access control.
🟢 Open to work — senior/staff Rust, systems, or security engineering. Remote EU or worldwide.

I care about correctness, total functions over panics, and systems that stay legible — to the next engineer and to the AI agents I now build alongside every day.
