You have found my site! :) I am originally from Mexico with Spanish ancestry. Currently, I reside in California, USA. I am a practicing Roman Catholic and in addition to my spiritual life and related interest, I am a research scientist and engineer specialized in cryptography. My special interests include all aspects of cryptology such as, cryptographic proofs, design of symmetric primitives, and cryptanalysis... including differential privacy (I wish I knew about this domain when I considered applied calculus to crytography). My background is in pure and applied mathematics, physics, and engineering (computer engineering, software engineering) and computer science. I have acquired very strong theoretical and applied experience in cryptography, networking (interestes in network security (L5/3) and routing protocolos), and French & Italian studies. With a natural love for abstract algebra applications, at the moment I am particularly interested in cryptographic proofs from PIOP, homomorphic encryption, post-quantum cryptography, and quantum cryptography research and development in all domains of implementation (hardware, firmware, and software).

See my résumé for qualifications, work, and projects.

My experience is in diverse areas including systems programming, advanced data structure design, circuirt design (analog & digital), embedded system design, networking (TCP/IP protocol stack, sockets programming), information security, applied mathematics (e.g., cryptography, qRNG constructions), development work (e.g., web design, web applications using different architectures, such as P2P, client-server), cloud (e.g., IaaS, PaaS, SaaS, BaaS, containers, microservices, k8s), and application-specific system design (cryptographic hardware), simulating, prototyping, and testing, in the hardware, software, and firmware domains and co-designs. For example, accelerating LMS (RFC8554) hashing in hardware, x86 compiler design, and the Montgomery-type reduction-free modular multiplier from my thesis which is a the most costly operation in both modern and PQC schemes as well as the corresponding attack vectors.

I am interested in the Internet across all layers (really enjoy routing algorithms) with my true passion being cryptology. In brief, I have a very strong affinity for mathematics, algorithms, and learning languages as well as experience with quantum algorithms and computation. I love finite field arithmetic. I love to learn new things and share what I learn: you may find my CMPE 209 notes in the above links and step by step DJA explanation. My background experience and passion enable me to teach myself anything and accomplish anything I set my mind to. I love to drive alone and enjoy meaningful collaborations. I have senior engineering experience, academic research collaborations with leading experts in the field of homomorphic encryption from leading R2 research institution Villanova University, and experience at a leading French engineering school. This March 2025 I executed my own LLC, Cryptologia and accepted a fully funded three year doctoral program in Palaiseau, France approximately one hour from the Paris. After demonstrating a capacity that exceeded the thesis directors and strongly defended my proposed thesis on Symmetric-Key-Based Post-Quantum Advanced Cryptography, I decided to leave the prestigious French institute of Télécom Paris in 2025 to pursue independent research in the USA and instead, allow the opportunity for an honorary PhD.

Other activities I enjoy are running, strength training, reading, going out in nature, and karaoke :)
