PROFILE

Jefferson Ricardini

Jeff Ricardini developed Cortex-M33 MPS3-AN524 platform support and packaging for the pq-code-package/mldsa-native repository, focusing on embedded systems and bare-metal development. He generalized the Nix packaging to support both M55-AN547 and M33-AN524 platforms, enabling reduced RAM mode by default to better serve constrained-resource environments. Using C, Nix, and Python, Jeff introduced compile-time configurability for stack allocation and expanded build tooling and CI coverage, including dedicated tests for the new platform. His work involved close collaboration with the pqmx team and cross-repository coordination, demonstrating depth in platform integration and attention to resource optimization for embedded targets.
