Dean Jay Mathew

I'm a British (UK) citizen with 10+ years of SaaS, open-source software and cyber security experience supporting world-renowned universities and intergovernmental organisations. I have led the delivery of large-scale multi-layered global technology solutions, working for diverse high-profile teams from UNESCO and the Singapore National Quantum Computing Hub and its partners. I have a demonstrated and fast-growing set of technical skills to match my leadership experience inlcuding professional C and Python application development, API integrations for Artifical Intelligence use cases, Linux SysAdmin, Dev/Ops, Post-Quantum Security, and FIPS.

My current focus is cybersecurity and post-quantum cryptography (PQC), with a strong emphasis on FIPS compliance and standards adoption. I can engineer and deploy hybrid classical/PQC servers and applications using ML-KEM (Kyber), ML-DSA (Dilithium), and SLH-DSA (SPHINCS+). My work directly aligns with FIPS 203/204/205 algorithm standards and the FIPS 140-3 validation pipeline, bridging the gap from research prototypes to compliance-ready product implementations. I take emerging cryptographic research and build it into practical, standards-compliant systems that can be deployed in regulated industries across the U.S., UK, and EU.
