Open to research + engineering work

I build secure systems with modern cryptography.

Cryptography Engineer / Researcher focused on Zero-Knowledge, Post-Quantum Cryptography, and privacy-preserving protocols. I like turning proofs and papers into production-ready code.

About

I work on cryptographic protocol design and implementation—especially systems that need privacy, auditability, and strong security guarantees. I enjoy writing clean, testable code and documenting decisions so systems can be maintained and verified.

What I do

  • Zero-knowledge concepts → circuits → proofs → integration
  • PQC evaluations & implementations (benchmarks + hardening)
  • Secure services and deployment: Linux, TLS, reverse proxy

What I care about

  • Correctness first (tests, threat models, reproducibility)
  • Security in defaults and ergonomics
  • Performance with evidence (profiling, measurement)

Currently learning

  • Advanced ZK systems and proof engineering
  • Formal methods basics for protocol reasoning
  • More production reliability (observability, SRE mindset)
