What I'm looking for

I seek roles where I can lead cryptographic architecture and advanced security programs, deliver high-assurance compliance, mentor teams, and work on blockchain, cloud, or research-driven security challenges.

I am an applied cryptographer and cybersecurity specialist with extensive experience designing, implementing, and auditing secure systems for government, finance, healthcare, and blockchain environments. I lead cryptographic architecture, FIPS-compliant solutions, penetration testing, secure software development, and evidence-driven compliance for high-assurance deployments.

I have delivered end-to-end secure ingestion pipelines, quantum-safe research platforms, privacy-preserving decentralized identity systems, and led security teams across cloud, AppSec, malware analysis, and red-team operations. I combine hands-on engineering (Python, Rust, Qiskit), formal methods, and practical adversarial testing to reduce risk and enable secure product delivery.
