An accomplished software engineer, I have over ten years of experience, comprising both development and operations. Fluent in multiple programming languages and technologies, I primarily aim to be versatile, and to be able to efficiently solve a broad range of problems. While particularly drawn to SRE, DevOps, Infrastructure or Backend Engineer roles, I welcome all opportunities that would allow me to work on challenging and varied problems as part of a talented team. Organisations implicated in open-source projects or tackling social issues are especially attractive.

Publications

Cardiac Interventional Guidance using Multimodal Data Processing and Visualisation: medInria as an Interoperability PlatformMidas Journal2012

Authors: F. Vichot, H. Cochet, B. Bleuzé, N. Toussaint, P. Jaïs, M. Sermesant

Summary: MedInria is a medical imaging software developed at Inria, which aims to provide clinicians with state-of-the-art algorithms for processing and visualising their images. In this article, we will focus on its use in pre-surgery preparation for cardiac interventions, and the difficulties arising from the lack of standardisation of certain data formats and visualisation conventions.

IpMorph: fingerprinting spoofing unificationJournal in computer virology 6, no. 42010

Authors: G. Prigent, F. Vichot, F. Harrouet

Summary: Nowadays, there are a variety of tools for easily identifying the TCP/IP stack's fingerprint of a target machine. IpMorph allows this fingerprint to be concealed, and even mimicks the fingerprint of a chosen TCP/IP stack. This is done through live session tracking and packet rewriting. Its effectiveness against tools such as Nmap, Xprobe2, Ring2, SinFP and p0f is also detailed.
