Summary
🤩
Rockstar🎓
Top SchoolAntoine Delignat-lavaud is a Senior Principal Researcher at Microsoft Research Cambridge with 12 years of experience building high-assurance secure systems, cryptographic protocols, and confidential computing platforms for privacy-sensitive industries like finance and healthcare. He combines academic rigor—a research doctorate from École normale supérieure—with hands-on engineering, contributing to formally verified projects such as HACL* and the F* proof-oriented language, including practical work on JavaScript backends and AES integration. His work spans protocols, platform services and silicon partner collaboration to enable encrypted processing (confidential machine learning) throughout the stack. Known for bridging formal verification and real-world deployment, he brings deep expertise in cryptography, formal methods, and systems design that few practitioners routinely apply together.

A Proof-oriented Programming Language
Role in this project:
Back-end Developer
Back-end DeveloperContributions:1 release, 248 commits, 21 PRs in 5 years 5 months
Contributions summary:Antoine made several contributions to the F* proof-oriented programming language, primarily related to the JavaScript backend. The user implemented a pretty printer for JavaScript Abstract Syntax Trees (ASTs) and made updates to support Visual Studio 2013 compatibility by upgrading FSharp.Core, adding NuGet package dependencies, and configuring build rules for parsing and lexical analysis files. Further work involved a shallow translation for the JavaScript backend, indicating involvement in generating code from F* specifications.

HACL*, a formally verified cryptographic library written in F*
Role in this project:Back-end Developer & Security Engineer
Back-end Developer & Security EngineerContributions:147 commits, 3 PRs, 103 pushes in 2 years 6 months
Contributions summary:Antoine made several code changes related to the integration and maintenance of a formally verified cryptographic library (HACL*) within the project, specifically focusing on the LowCProvider and QuicProvider components. These changes included preparing for miTLS merge by updating and adding components, adding implementation multiplexing for AES implementations, and fixing issues related to the packet number encryption. The contributions demonstrate expertise in cryptography and its integration with a formal verification framework.
