01Delivered
Real problems, solutions in production and measured numbers.

Ecopassport
An environmental-labelling widget embedded on major e-commerce sites.
Problem. France's AGEC law requires environmental information on products. At Holis, it had to appear directly on e-commerce clients' product pages: third-party code, injected into pages we don't control, that must neither slow down nor break the host site, across 17 product categories.

GPConnect
A France ↔ West Africa parcel marketplace where trust is enforced by code.
Problem. Between France and West Africa, travellers ("GPs") sell the spare kilos in their luggage. This informal market runs on WhatsApp groups: no verified identity, no proof of handover, no recourse when things go wrong.

MyLittleAnsible
A command-line infrastructure-as-code tool inspired by Ansible, written in Python.
Problem. Configuring servers by hand is neither reproducible nor auditable. The brief: understand what Ansible does by building it yourself, that is, apply a YAML task list to an inventory of machines over SSH.

04Sender
Before writing code, I delivered food across Paris. It left me with one simple idea: a delivery only counts if it arrives, on time and intact. That's what I aim for in software.
To me, engineering is about proportion: protection that matches criticality, effort that matches what was measured. I write the safety net before touching critical code, and I'm willing to drop a component that isn't worth maintaining.
I grow best in a small, demanding product team with code review, measurable goals and honest post-mortems.
