Lionel Sambuc is a systems-focused software engineer with 13 years of experience building low-level and infrastructure solutions from embedded firmware to distributed services. Based in Lausanne, he has delivered kernel and toolchain work for MINIX and ARM targets, implemented firmware parsers in Rust, and optimised complex stacks including PostgreSQL, Java simulators and CI/CD pipelines. He combines rigorous documentation and project management with hands-on skills in deployment (DockerSwarm, Kubernetes, bare-metal clusters), AD on Linux, and hardware testbench definition to ensure reliable production systems. At EPFL and BlueBotics he led federated data deployments and integrated partner solutions across hospitals and labs, improving portability and security. An active contributor to MINIX, his commits show deep familiarity with kernel internals and memory/process management—evidence of strong systems programming expertise that few application engineers possess.
