Hermès is a luxury goods company that aims to create exceptional products combining French craftsmanship and excellence.

The company has 25,000 employees worldwide, with over 15,000 based in France, and a turnover exceeding 15 billion euros in 2024.

I joined the Cart team as a Node React developer at Hermès Digital.

I participated in the design and maintenance of a distributed e-commerce platform.

Squad of 9 people: 6 developers, 1 PO, 1 BA, 1 tester.

As a Node React developer, I was responsible for:

- Designing and maintaining a distributed e-commerce platform applying software craftsmanship principles

- Developing complex business logic for the cart and catalog domains (real-time stock management, quantity limits, dynamic pricing)

- Creating automation services for order validation and shipment preparation

- Implementing an event-driven microservices architecture (Kafka, SQS) to ensure system resilience

- Applying DDD and Hexagonal Architecture principles to isolate business logic and facilitate maintenance

- Promoting a quality culture through TDD/BDD and contract testing (Pact) to ensure integration stability

I contributed to the following developments: Development of an e-commerce platform managing several million customers per day worldwide and processing thousands of daily sales. The system maintained 100% availability during peak traffic, especially during holiday seasons when demand is particularly high. This global resilience contributed to supporting Hermès' exceptional growth, which saw a 15% increase in turnover in 2024, confirming the robustness of the implemented architecture.

As a freelance Web Developer Mentor, I support students in the "Web Integrator" program, helping them to develop their skills to become autonomous and qualified professionals in the job market.

Format: Weekly individual video conferencing sessions and asynchronous follow-up.

As a Mentor, my mission consists of:

- Guiding students in the completion of their professional projects in HTML, CSS, JavaScript, and React, by setting clear and achievable goals.

- Unblocking complex technical situations by encouraging problem-solving and transmitting effective development methodologies (debugging, testing, etc.).

- Preparing students for their future careers by simulating technical interviews, assisting with portfolio building, and sharing advice on the tech ecosystem.

Through my role, I have supported over 10 students to obtain their diplomas, with a success rate of over 75% in project defenses. I have contributed to their technical skill development and self-confidence, enabling them to successfully enter the job market as web developers.

The Agence du Numérique de la Sécurité Civile (ANSC) is a public administrative body whose objective is to develop the unified IT system NexSIS 18-112 for the digital transformation of emergency communications for fire and rescue services. This national project, with a budget of 237 million euros over 10 years, concerns more than 100 French fire and rescue services to handle emergency calls from numbers 18 and 112.

I joined the team as a Node Angular developer at ANSC.

I participated in the development of the SGO (Operations Management System) application, an essential component of NexSIS 18-112, which allows the deployment of operational agents and resources to intervention sites.

Squad of 8 people: 5 developers, 1 PO, 1 co-PO, 1 tester.

As a Node Angular developer, I was responsible for:

- Developing the Angular interface and Node.js APIs with PostgreSQL/Sequelize for operational resource management

- Designing optimization algorithms to propose alternative solutions in case of unavailability

- Implementing a DDD and Hexagonal architecture with TDD/BDD practices to ensure critical reliability

- Developing in event-driven programming to ensure real-time responsiveness of operations

I contributed to the following developments: Development of the SGO system used by all French fire and rescue services as part of the national deployment of NexSIS 18-112. This critical system manages emergency interventions throughout the national territory, handling calls from numbers 18 and 112 for millions of citizens. The project represents a saving of 350 million euros compared to individual systems, modernizing the French rescue chain and improving interoperability between all civil security actors.
