Work

Projects

A selection of work, for my clients and on my own.

// Hosting

For this, I run a Linux VPS and own a domain name.

The applications run in Docker containers; this site is deployed by Kamal 2 from GitHub Actions on every merge.

This let me practise system administration, security, deployment and continuous integration.

Deltarm

A governance, risk and compliance (GRC) platform for CAC 40 groups, built by a team of six developers whose work is fully driven by AI, under human supervision.

For each ticket, agents implement, review and test; the team frames the work, arbitrates, runs acceptance tests and decides on every merge.

Real teamwork: shared conventions and skills, cross-review between humans and agents, and a reliable CI so that agents can move on their own. In six months, we delivered what a conventional team of the same size would have needed more than three years to build.

SecOps Forces

A cybersecurity SaaS platform for SMEs and mid-size companies, which I build as the sole developer of the application.

It protects email and domains, runs phishing campaigns, monitors vulnerabilities and continuously audits Microsoft 365, with an AI assistant that answers from each organisation's data.

My professional website

A site designed as a showcase of my offer: an AI assistant that answers from my background, a command palette (Ctrl/⌘+K), a light, dark or system theme, in French and English.

Its redesign was carried out with AI agents under my supervision, from ticket to live acceptance testing. It is deployed on my VPS with Kamal 2 from GitHub Actions.

Web3-blog

A personal decentralized application (dApp) enabling users to create and read blog posts, with metadata stored on IPFS and CIDs anchored on the Sepolia testnet blockchain.

The Web3 Blog is a personal project designed to explore decentralized content creation and storage.

Users can create and read blog posts, with metadata stored on the InterPlanetary File System (IPFS) and Content Identifiers (CIDs) anchored on the Sepolia testnet blockchain.

This approach ensures both decentralization and immutability of content.

CEA-Moonshot

Development of a Web 3.0 SaaS dashboard for the CEA, the French Alternative Energies and Atomic Energy Commission.

It allows monitoring greenhouse gas emissions (like CO2) on a customizable dashboard.

The data comes from multiple laboratories and is anchored on the Blockchain.

This SaaS provides a data auditing feature, which was challenging due to multiple data architectures and dynamic processes provided by each laboratory. Additionally, the SaaS offers local data auditability. To handle both audit methods, I implemented a microservice architecture involving Docker containerization management.

A data audit involves interacting with smart contracts to verify that the data is properly anchored and trustworthy.

You will find a demo using fake data.

Quizzer-llm

This project is about a Quiz where the questions and answers are managed by an AI LLM model: GPT 4o mini.

Through this POC, I share a way to use an AI model through a REST API, and how we can interact with a frontend.

Ylunch

A project carried out during my studies and presented to the examination jury.

The application offers meal reservations by students at restaurants around the school.

This project is not in production, but it is deployed for demonstration. This allowed me to cover a wide range of skills: project management, client management, mock-ups, design, realization, communication, and presentation of a complete project.

On the technical side, I applied all my knowledge of the time: software architecture DDD, unit testing, development, deployment, and continuous integration (CI/CD), and security.

It is a web application with a REST API backend and a React frontend. The backend is in Dotnet with a SQL Server database. Unit tests are present, and the code is organized according to the DDD model

AI Calculator

This project delivers a basic calculator in which you have to draw the numbers, which are interpreted by a Deep Learning CNN neural network to be calculated.

This handwritten digit detection AI model was configured and trained by me on a dataset, which is exposed through a REST API, consumed by a frontend, and used to calculate the drawn numbers.

Hovering over the numbers, you can see the model's prediction statistics.
