Biography

As a network and system engineer, I am able to design complexe IT infrastructures, using new technologies like cloud computing, NetDevOps methodology, automation processes and security threats consideration. I’ve always enjoyed designing, setting up and maintaining networks of various sizes, as well as deploying complex infrastructures that are using these networks.

I enjoy working as part of a team to come up with innovative solutions that meet customer’s needs. In my spare time, I’m working on various application development projects (mainly Java, Python and Golang) and automating my homelab (Proxmox, Terraform, Ansible…).

I’m also a fervent defender of the values of sport. I teach skiing, I play golf and I run when I have time.

Experience

Scientific Collaborator

Institute of Artificial Intelligence and Complex Systems

February 2024 – Present Switzerland

As a scientific collaborator for the iCoSys applied research institute, I am working on GPU architectures executing machine-learning tasks. The stack mainly uses Kubernetes and NVIDIA GPUs to provide an easy way to schedule inference workloads, and Slurm to enable experiments and trainings on a queue-based scheduling system.

Scientific Collaborator and Lecturer

Haute école d’ingénierie et d’architecture de Fribourg

September 2023 – Present Switzerland

As a lecturer for future engineers, I teach the Telecommunications and IP Networks course with the following content :

Introduction to network topologies
OSI reference model
Internet Protocol
Routing and switching
Medium access (CSMA/CD, TDMA, FDMA)
Many protocols (ARP, DNS, DHCP, SSH, TCP, UDP, HTTP, RIP, OSPF…)

I am also working as the main sysadmin of many clusters (Slurm, Kubernetes, vSphere, OpenStack, Proxmox, storage).

Head of a holiday entertainment team

Groupe Romanée

June 2022 – September 2023 France

For 2 years, I supervised a team of entertainers during July and August. I carried out several recruitment sessions and drew up clear schedules and guidelines for my team.

Sysadmin internship

CISEL Informatique SA

April 2021 – June 2021 Switzerland

For 12 weeks, I worked on designing and building a secure CI/CD pipeline to deploy an application on a Kubernetes cluster, with code, Docker image and runtime environment analysis.

Projects

Carbon aware spatio-temporal workload shifting using FLUIDOS

As part of the European research project FLUIDOS, this project aims to achieve carbon optimizations through strategic workload scheduling on multiple Kubernetes clusters, leveraging the spatial and temporal variations in the carbon intensity of electricity. This approach requires scheduling algorithms capable of predicting the availability of low-carbon electricity and available resources, and subsequently dynamically adjusting workloads to synchronize with these periods. Project grade: 5.8/6. Photo by Growtika on Unsplash.

Measuring the efficiency of an heterogeneous GPUs cluster

The iCoSys applied research institute uses a large number of GPUs to carry out various types of experiment. This project analyses and reports on the efficient use of the GPUs cluster, with suggestions for significant improvements. Project carried out under a fixed-term contract.

Managing RAM memory in containers

This project aims to study and understand the memory management of containerised applications, by studying the management provided by the Docker Engine and the Kubernetes orchestrator (allocation, limitations, monitoring, etc.). Project grade: 5.6/6. Photo by Venti Views on Unsplash.

Evaluating and testing the computing capacities of different clusters

As part of this project, I have used Terraform and Ansible tools, as well as the High Performance Linpack benchmark to measure and compare the computing capacities of various clusters (including technologies like vSphere / ESXi, OpenStack and Kubernetes). Project grade: 6/6. Photo by Taylor Vick on Unsplash.

Go Tic Tac Toe

A Tic Tac Toe game made in Golang using an SQL API to store game data and a language system. This project was made as part of the “Programmation élégante en Go” course at HEIA-FR. Project grade: 5.75/6. Photo by Matthew Davis on Unsplash.

Universe Simulator

A universe simulator developed in Java, handling multiple types of elements interacting with each others. Elements are placed on a board and are able to move, get near another one, get away… This project was made as part of the “Génie Logiciel 1” course at HEIA-FR. Project grade: 5.9/6.

Digital Sport

A website that represents a virtual gym where users can sign up, carry out exercises, get in touch with trainers, select different subscriptions, etc. There is a member, coach and admin panel. The database used is PostgreSQL and the main language is PHP. The project is based on the MVC software design pattern developed entirely from scratch. This project was made as part of the “Projet de 1ère année” course at Annecy’s IUT. Project grade: 20/20. Photo by Risen Wang on Unsplash.
