About Philippe

I am a passionate Backend Developer with solid expertise in C# API and Azure. With several years of freelance experience, I have collaborated with renowned companies to tackle complex technical challenges and manage large volumes of data.

Currently, I am a member of the R&D team at TotalEnergies, where I am facing the exciting challenge of managing a vast data flow. My role involves managing time series from multiple providers, which requires mastery of concepts related to the collection, storage, and analysis of massive data.

Previously, I held a key position at Edenred, the leader in meal vouchers, where I was the sole Backend Developer responsible for the MyEdenred application. In this role, I successfully delivered a robust and high-performing application that met the strict requirements of millions of users.

My passion for Backend development is reflected in my commitment to creating high-quality solutions while paying close attention to performance. I am constantly on the lookout for the latest technologies and best development practices to deliver optimal results.

If you are looking for a Backend Developer focused on quality and innovation, I would be delighted to discuss your needs.

    I am taking on the challenge of managing a large volume of data, particularly time series from multiple providers. During this experience, I have acquired in-depth expertise in time series management.

    When I joined the team, the existing project had significant performance and stability issues. Every change made incurred considerable costs in terms of time and money. To remedy this situation, we decided to start from scratch, returning to the initial requirements. This required a complete review of the architecture and the proposal of a new robust, fast, and easily maintainable system.

    Working collaboratively with data scientists, I also gathered specific data needs for their work. My role consisted of retrieving data from multiple providers, transforming it into a common format, and inserting it into databases.

    Thanks to our work, we are significantly improving the project's performance, stability, and profitability. I am proud to contribute to this complete overhaul and to provide a reliable system for data scientists to carry out their activities.

    This experience reinforces my interest in the technical challenges related to managing large amounts of data and the resulting performance.

    I was assigned to SUEZ to work on existing applications as part of a maintenance contract.

    During this assignment, I had the opportunity to contribute to the development and improvement of two key applications.

    The first application focused on detecting overconsumption and water leaks. I participated in implementing features for data analysis and alert generation.

    The second application was dedicated to calculating valued hours for payroll. I contributed to optimizing the calculation algorithms.

    Working at SUEZ allowed me to understand the specific challenges of the water sector and to contribute to applications with a direct impact on water management and payroll processes. I was able to collaborate with a dynamic team and provide effective technical solutions.

    I am proud to have played an active role in improving these applications and delivering functional and reliable solutions.

    This experience allowed me to consolidate my FullStack development skills while familiarizing myself with the challenges of maintaining and evolving existing applications. Furthermore, it strengthened my interest in backend development and Microsoft technologies.
