Five years of full-stack and platform engineering: the deployment tooling behind 1,500+ engineers at Criteo, an IoT edge stack at Schneider Electric, and SignalAtlas, a product I designed, built and run in production on my own.

I take one problem at a time and own it from the first conversation to the last deploy. Every engagement ends with code your team can run without me.
Features from the database schema to the React screen. New products, rewrites of a legacy module, or the next six months of a roadmap your team cannot staff.
You getFeatures shipped with tests, migrations and the screen that uses them.
Deployment tooling, pipelines, containers, and the dashboards that tell you it works. The same work I do today for a platform used by 1,500 engineers.
You getReleases that take minutes, alerts that mean something, and a runbook.
MCP servers, chat bots and agent workflows that remove recurring interruptions. I built one at Criteo that answers the platform team's support questions, and I work with coding agents every day.
You getFewer tickets, faster answers, and engineers who stay in flow.
Go, Python and C++ services on constrained Linux devices, with industrial protocols and a cloud link. Two years of this at Schneider Electric, in Boston and Grenoble.
You getSoftware that runs for months on a box nobody can reboot.
Real systems, in production, with the numbers that were true when I worked on them.
Software engineer, CD platform team
The in-house platform 1,500+ Criteo engineers use to ship to production. I own features end to end across a Groovy back end, Angular and React front ends in TypeScript, C# and Python services, Concourse CI jobs and workloads on Mesos and Kubernetes.
Design, engineering, infrastructure and operations
A market-analysis product I took from first commit to production, with AI coding agents in the loop. Web app in React, TypeScript and Vite; mobile app in React Native with Expo; Node.js and Python services behind both.
Software / DevOps engineer, R&D IoT
Micro-apps in Go and Python for an industrial edge platform, deployed with Docker, Kubernetes and EdgeX Foundry inside a 300-person engineering organisation. Contributor to the MARGO open orchestration initiative.
Edge computing engineer
Ported the CCSDS 122 satellite image-compression algorithm to a Kalray many-core processor and parallelised it across 80 cores in C / C++ with OpenCL and OpenMP, for a 12-person proof-of-concept team. Docker-based validation and GitLab CI with automatic tests.
An autonomous car on STM32MP1 with STMicroelectronics (GTK interface, lidar and BLE mapping, A7 / M4 core communication, new PCB). Embedded C on Raspberry Pi for FlyTek, run as a full V-cycle from spec to delivery. A full-stack internship on a VPN user platform at Orb Group in London (JavaScript, PHP, SQL), where I also mentored the next interns.
Highlighted: what I reach for first. The rest I have shipped with in production.
Clients hire me to remove a problem, not to add meetings. Here is what that looks like week to week.
Based in Paris (CET), fully remote, with real overlap for every European team. I join your Slack, your repo and your rituals, and I have worked on-site in Boston and London when it mattered.
Nothing goes to production without automated checks and a page that explains how to run it, roll it back and debug it at 2 a.m.
A demo every week, written updates you can forward, and decisions recorded where your team will find them later.
I use coding agents daily to move faster on the repetitive parts, and I review, test and own every line that lands.
Specs, code review, stand-ups and client calls in either language. Native French, fluent English after two years in the US.
Typically 3 to 12 months, full time or part time, invoiced business to business. Day rate on request, with a fixed scope when the problem is well defined.
Engineering school in Angers, then four companies in three countries. The full history, with every detail, is on LinkedIn ↗.

A short note with the problem, the stack and the timing is enough. I usually reply within a day, and the first call is free.
