About Me
I’m Dr. Thomas Pani, a freelance protocol and system correctness R&D engineer and researcher.
I help teams build software protocols where correctness and resilience are paramount, and failure in production is not an option.
Security audits are snapshots. I design & build system correctness.
I combine deep (semi-)formal methods and security expertise with hands-on engineering.
I build and integrate software that make systems robust by design.
Fuzzing & Simulation
I build integrations and deploy advanced techniques — using tools like AFL, libFuzzer, cargo fuzz, the Wake fuzzer, or Echidna/Medusa — engineered for maximum coverage, reproducibility, and depth to uncover critical system behaviors.
Formal Modeling & Verification
Leveraging powerful tools like Alloy, TLA+, Lean4 or Certora Prover, I apply formal verification to prove the correctness of your protocols and systems, ensuring reliability beyond traditional testing.
Training & Applied Research
I provide training and mentorship in formal methods, fuzzing, and security best practices. Applied research in protocol design and security, including implementation guidance, paper review, and public speaking.
Security Consulting & PL Advice
Offering expert guidance on security strategy, threat modeling, audit preparation, post-deployment monitoring, and leveraging programming language design for enhanced system correctness and security.

Work With Me
I take on a small number of high-leverage projects where security is part of system design—not bolted on at the end.
