Bespoke Protocol + Software Correctness R&D

Faults and vulnerabilities lurk everywhere.
Your systems deserve a future free from them.

Dr. Thomas Pani

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, Echidna/Medusa engineered for maximum coverage, reproducibility, and depth to uncover critical system behaviors.

Formal Verification

Leveraging powerful tools like TLA+, Lean4 or Certora Prover, I apply formal verification to prove the correctness of your protocols and systems, ensuring reliability beyond traditional testing.

Applied Research & Technical Writing

Specializing in protocol and systems R&D, including implementation guidance, paper review, and public speaking — all grounded in deep technical understanding and hands-on experience.

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.

Some languages I work in: 🛠️ Solidity 🦀 Rust 🐹 Go 📐 Lean 🐍 Python 🟦 TypeScript

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.
