Freelancer profile translated to English.

Description

I am David ROUSSEL, an IT professional with 16 years of rich experience in various roles, from production engineer to development project manager. I am ITIL v3 and ScrumMaster certified, with skills in Agility, Data Science, AI, and Web development. My strengths lie in my analytical ability, customer service orientation, and rigor.

I have excellent knowledge of the banking/insurance sector, having worked for reputable companies like AXA, BNP Paribas, and LCL. Currently at LCL, I am an application manager, developer, and production engineer. My versatility and ability to quickly master new technologies are major assets.

As a project manager at BNP Paribas, I improved the quality of information for the unpaid check information system and implemented new requirements. I played a key role in coordinating activities between teams and facilitating working sessions.

I also worked at AXA France, where I held the role of consultant and project manager. I led the design, development, and management of an application for portfolio refreshing.

My experience at Generali Assurance as an infrastructure/production project manager allowed me to manage ambitious projects, such as server migration and the implementation of a comprehensive data control system.

In summary, I am a versatile expert with in-depth knowledge of information systems. My technical skills, combined with my project management skills, make me a valuable professional in the IT field.
