  • Pytrace (Rust), able to render videos and high-quality images, also available as a Python library
  • COCass (OCaml), native compiler for a small C without floating-point arithmetic, but with added exception handling
  • Forklang (C), a small non-deterministic language to validate parallelized protocols
  • Billig (Rust) is a DSL to record expenses, ergonomic enough for my current daily usage but still a work in progress
  • Chandeliers (Rust) is a proc macro library that implements the Lustre language inside Rust.
  • Minihell (OCaml) is a type inference engine for a toy language implemented for the MPRI class 2.4 (Functionnal Programming). The language is ML-style without polymorphism and supports inductive algebraic datatypes.

    Tree Borrows

    I have worked at MPI-SWS, Saarland (Germany) on the miri Rust interpreter to develop Tree Borrows, an aliasing model. Presentations of Tree Borrows have been given online at RFMIG and in person to teams from ETH Zurich and Inria Saclay. You can look at the material and a recording.
