PROFILE

John Lees

Worked on the bioconda/bioconda-recipes repository to enhance packaging and build systems for bioinformatics tools, focusing on Rust-based applications and cross-platform compatibility. Delivered features such as Apple Silicon (M1) build support for PopPUNK, modernized Python compatibility for Gubbins, and introduced a new Rust sketchlib recipe to streamline installation and integration. Upgraded dependencies and build requirements, aligning with the latest Rust toolchain and improving CI reliability. Addressed reproducibility by updating source URLs and checksums, ensuring secure and consistent builds. Utilized Rust, YAML, and CI/CD practices to reduce installation friction, broaden hardware support, and facilitate maintainable workflows for researchers.
