I design and harden your critical platforms — from bare metal to Kubernetes clusters, from sovereign cloud to AI agents in production.
Profile
French citizen — based in Paris. Technical reference on critical environments: bridge between production and development, delivery automation, security and large-scale operations (hundreds of VMs, monitoring, storage).
Professional experience
Assignments with at least two entities of the ministry: Bercy HUB for the Nubonyxia project, then the DGFIP (taxes) for the RADAR project.
Designed a test bench for real-time software : verified the chaining between Linux and the real-time application .
Since 2005 , supporting RYC , a business assistance structure (advice on administration , pre-accounting notably with Sage Coala ). IT and office support: Windows workstations on the client side; Linux servers for infrastructure, with folder sharing via Samba — the Coala software running on the Windows workstations .
Startup in the small modular nuclear reactor (SMR) sector; mostly Windows-based information system, with a decision to invest in a HPC platform for simulation and scientific computing.
Hired as part of the OnAir project: migration of part of the radio business information system to a Linux software base, while the legacy until then was essentially Windows-based.
The B2I bureau (engineering and integration) bridged the production / operations teams and the R&D / studies teams — in short, the glue between development and prod. A small team of about ten people splitting up the entire application portfolio of the institution. Profiles deliberately polyvalent: combining operations …
After the Sungard experience, joined INPI — about nine years there, a very rich experience. On arrival: no virtualization yet, no containers as we know them today; services were still massively installed on dedicated hardware ("bare metal" approach). Linux was not yet dominant across the fleet: a lot of Windows and pro…
Après l’expérience à l’UCAD, mission chez Sungard (une partie de l’offre GP3 existe aujourd’hui sous la marque Neoxam) : produit phare Global Portfolio 3 (GP3), solution de gestion d’actifs (asset management) pour banques et assureurs. Part très importante du marché : en France, la quasi-totalité des banques et assureu…
Institution muséale, +300 salariés. Parc mixte : postes de travail Windows et postes Linux ; serveurs Linux (production Debian, etc.) et stack Windows/Novell. Pas encore d’Active Directory : l’institution reposait sur Novell, dont l’annuaire (NDS / eDirectory) centralisait utilisateurs et ressources — l’équivalent fonc…
During studies at EPSI , student job at DGC , a training centre in the same group as the school. IT support and fleet management of the workstations dedicated to students : Windows NT 4 , then Windows 2000 . Created images with Ghost (Symantec / Norton Ghost) and multicast deployment to re-image machines regularly; Win…

AI & augmented engineering
AI is not a fad for me: ever since accessible LLMs appeared, I've made them both a daily working companion and an experimentation field. I use them to code, design and reason — and I build agents that run in production, including local inference to preserve data sovereignty.
Personal projects & commitments
In 2026 , leading the creation of a web portal for managing artwork collections , with AI assistance .
In February 2025 , took part in a hackathon dedicated to artificial intelligence : our team built a voice chatbot able to extract and quickly serve information from the French Legal Code . Goal: simplify access to law th
Since 2023 , developing a software portal for data scientists , focused on data science and AI .
In 2022 , volunteer participation in the creation of an art institute in Échirolles , as IT expert (advice and rollout of the digital base).
In 2020 , built websites with WordPress and Elementor for small entrepreneurs .
Le Signe — artwork collection management software: Groovy (backend), JavaScript and React (frontend). Tested and developed around 2019 as part of collection inventory at Le Signe , French national centre for graphic desi
In 2013 , designed an automatic MCQ correction solution built on the open source Auto Multiple Choice (AMC) tool: generation of unique questionnaires per exam session (questions and answers in a different order from one
