About Guillaume

With 10+ years of experience building automated pipelines for large-scale bioinformatics and scientific computing, I have a deep understanding of the real-world constraints research and data teams face in managing their infrastructure.

I help teams design and operate reproducible, secure, and scalable cloud and HPC environments, combining modern infrastructure tools (Terraform, Ansible, Docker, AWS) with the scientific computing stack (Slurm, Nextflow, Conda, Singularity).
