Projects

This portfolio documents applied work across cryptography, post‑quantum cryptography, quantum computing, and security engineering. Each project implements discrete technical controls, mathematical algorithms, or automation tooling demonstrating the skills required for cryptographic engineering, threat modeling, and quantum‑safe infrastructure design.

Technical domains:

  • Cryptography
    Symmetric/asymmetric algorithm implementations (RSA, AES, Diffie‑Hellman, ECC), modular arithmetic, cryptographic protocols (TLS, PKI), post‑quantum cryptography (Kyber, Dilithium, SPHINCS+), key management, hybrid cryptographic systems.

  • Quantum Computing
    Qiskit simulations (Shor's algorithm, Grover's algorithm, quantum circuits), quantum threat modeling, post‑quantum cryptography research (lattice‑based, hash‑based, code‑based).

  • Security Engineering
    Cryptographic risk assessment, threat modeling (STRIDE, MITRE ATT&CK), dependency mapping, key lifecycle management, zero‑trust architecture principles, protocol integration.

  • Programming & Automation
    Python, C, liboqs, OpenSSL, Qiskit, Git, Jupyter, Matplotlib, perf/Valgrind for security tooling, cryptographic benchmarking, log parsing, and workflow automation

Project Chimera: The Complete PQC Migration Capstone

I'm excited to announce Project Chimera, my 6‑month capstone project that simulates the complete post‑quantum cryptography (PQC) migration of Chimera Capital Partners a fictional $50B+ hedge fund with 9 global offices and millisecond‑sensitive trading algorithms.

The Challenge: Quantum computers will soon break RSA and ECC the cryptography protecting trillions in financial assets. Chimera faces critical gaps: no cryptographic inventory, reliance on vulnerable algorithms, no crypto‑agility, and no migration roadmap.

My Mission: As a Junior Cryptography Security Architect, I will assess current cryptographic risks, design a quantum‑safe architecture, implement key controls, and deliver a structured migration strategy.

What I'll Deliver:

  • Cryptographic Risk Assessment Report

  • PQC Architecture Design Document

  • Cryptographic Control Implementation Plan

  • PQC Migration and Governance Strategy Report

 

Technical Domains: Cryptography (RSA, ECC, Kyber, Dilithium, hybrid TLS), Quantum Computing (Shor's algorithm, Qiskit), Security Engineering (STRIDE, MITRE ATT&CK, key management), and Performance Benchmarking.

Timeline: 6 months (2026)

I'll be sharing weekly updates risk assessments, architecture diagrams, key management strategies, and migration roadmaps. Follow along as I build enterprise‑grade cryptographic engineering solutions.

Coming soon………..
