Acerca de Raúl

I'm a software engineer specialised in cryptography and secure systems, with hands-on experience in Fully Homomorphic Encryption (FHE), post-quantum cryptography and secure backend development across R&D and defense environments.
I help companies review and improve their cryptographic implementations, integrate encryption mechanisms into real systems, and produce clear security documentation for technical and non-technical audiences.
If your team is handling sensitive data, preparing for a security audit, or integrating advanced cryptographic techniques and needs a specialist who can deliver practical, production-ready guidance — I can help.
