Work Experience

DevOps Engineer

2018 - 2018
SIpf
  • Trained and guided the ops team in the use of cloud technologies and DevOps culture.
  • Created a website CD pipeline which builds it on a GKE cluster and deploys it on a local Docker-Swarm cluster.
  • Set up a local staging Docker-Swarm cluster.
Technologies: GitLab, Python, Docker, Google Kubernetes Engine (GKE), Kubernetes

DevOps Engineer

2015 - 2018
EasyMile
  • Migrated our cloud workloads into Kubernetes clusters (built with Kops); the previous infrastructure (consisting of virtual machines) had to be manually managed before I implemented the migration.
  • Fully automated our hybrid build farm (physical local machines, cloud builders, CI server) installation.
  • Set up continuous-integration pipelines for our embedded systems (various types of software and OSes).
  • Improved our multi-team release process via automation and organizational changes.
  • Reverse-engineered our manually installed embedded OS and created flashable Linux images from it.
  • Created a toolbox to install, manage, and troubleshoot our vehicles with a nice graphical interface for our deployment team.
Technologies: Amazon Web Services (AWS), Groovy, Buildbot, Jenkins, CMake, Ansible, Terraform, Packer, Kubernetes, Docker, Bash, Python

System Integration Technician

2014 - 2015
EVS
  • Improved teamwork and collaboration by migrating from SVN to Git and used GitLab as the team forge.
  • Developed continuous integration pipelines (artifact publication, staging deployment, sandbox VM generation, and more).
  • Optimized, automated, and stabilized the team-release process enabling the team to release on time with a known set of features and issues.
  • Reduced the complex (multiple machines, multiple OSes) production installation process from 3–4 hours to 30 minutes.
Technologies: Bash, CMake, SonarQube, GitLab, Jenkins, Python

Developer

2010 - 2014
Cofely Ineo
  • Set up and maintained a Jenkins build farm installed on VSphere.
  • Worked on a supervision software graphical interface in C++ and Qt4.
  • Wrote functional tests with our homemade framework and Python.
  • Built a custom C++ dependency manager to assemble our developer workspace with our multiple modules (a bit like Conan).
  • Created a monitoring graphical interface for our modular supervision tool.
Technologies: CMake, Bash, Jenkins, Python, Qt, C++
