    Analysis and Understanding: I began with a thorough analysis of the existing POC to understand its features, limitations, and strengths. This step was crucial for identifying necessary improvements and optimization opportunities.

    Architecture and Scalability: I designed a technical architecture capable of supporting significant load increases. This includes performance optimization, implementation of redundancy mechanisms, and efficient resource management to ensure maximum availability and reliability.

    Development and Integration: I developed new features and integrated third-party solutions to enrich the platform. I ensured that each component was well-integrated and functioned harmoniously with the entire system.

    Security and Compliance: Data security and regulatory compliance were at the core of our concerns. We implemented robust security measures to protect user data and ensure compliance with current standards.

    Testing and Validation: A series of rigorous tests were conducted to validate the platform's performance, security, and reliability. We used automated and manual testing methods to ensure the platform meets user requirements.

    Deployment and Support: Finally, I assisted CheckTheNet in deploying the platform and provided ongoing support to ensure a smooth transition. I trained internal teams to manage and maintain the platform autonomously.

    Thanks to our intervention, the initial POC was transformed into an industrial platform, offering an optimal user experience and performance that meets expectations, allowing navigation through 30 million publications and extraction of key information for informed decision-making.

    September 2020 - October 2024 (4 years and 1 month)
    Paris, France
    Over four years at DGEX Solutions, a division of SNCF Réseau, I had the opportunity to work on critical and exciting topics.

    Our mission was to design, develop, and deploy innovative expert systems to optimize the maintenance of the French railway network. The projects were part of the digital transformation of railway maintenance, focusing on leveraging data and cutting-edge technologies to improve operational efficiency.

    The systems created enabled field agents to effectively identify, prioritize, and track maintenance operations. These innovations made it possible to collect and analyze real-time data on the network's status, implement algorithms to prioritize maintenance actions, and optimize intervention planning.

    Thanks to these technological advancements, it was possible to significantly reduce train downtime and minimize the impact on daily operations. The economic impact of the project was significant, allowing SNCF Réseau to achieve savings of several million euros by optimizing the use of the network's maintenance capacities.

    This work contributed to the modernization of SNCF Réseau's maintenance practices, and not only led to cost reductions but also improved the reliability and safety of the French railway network, demonstrating the profound impact that technological innovation can have in the field of critical infrastructure.
