Top SchoolThomas Dubuisson is a Staff Software Engineer in Portland with 26 years of experience specializing in security engineering, distributed systems, and applied cryptography. He co-founded Muse.Dev and built the static-analysis service Lift, bringing formal verification and developer-friendly tooling into real-world CI workflows before the company's acquisition by Sonatype. At Paxos he now focuses on making financial transactions trustworthy through secure design, code audits, and developer education, while still contributing hands-on in Go and Rust. His research background at Galois produced prototypes and papers on multiparty computation and cryptographic leakage analysis, and he has practical open-source contributions to notable projects like Cryptol and the Haskell Hackage server. Colleagues rely on him to translate research-grade security into production-ready systems and to run programs that turn engineers into security representatives.

Role in this project:
Back-end Developer
Back-end DeveloperContributions:46 commits, 5 PRs, 22 pushes in 2 years 1 month
Contributions summary:Thomas primarily focused on improving the Cryptol language's core functionality, particularly related to random number generation for testing and evaluation. They addressed issues by refining the `randomWord` function to produce a more uniform distribution and switching to higher-quality random number generators. Additionally, the user made several bug fixes, including a fix related to bit size calculations and handling of index errors within the REPL. Furthermore, they implemented the `:writeByteArray` and `:readByteArray` commands, enhancing the REPL's usability.
