About Sebastien

Cross-functional player in complex and heterogeneous environments, ensuring operational readiness, I have successfully completed projects by coordinating technical and functional teams, both with internal resources and external partners.

Infrastructure redesign project, implementation of DRP / BCP, ERP change project and production launch of new tools. Throughout the project milestones, regardless of the methodology used (V-cycle, agile), I ensured constant communication to all stakeholders, from risk identification to compliance with deadlines and schedules.

The provision of dashboards (Office suite) is also part of my responsibilities, reappropriation but also design of performance indicators.

Based on my experience in transition management or team management, the quality of deliverables (process, procedure, UAT, VABE) has always been an important element in the virtuous circle of continuous improvement. Whether it is to reduce processing times, ensure the quality perceived by customers or the complete review of processes.

Focus on customer satisfaction (internal and external), especially during the outsourcing of support services on behalf of the client Capgemini.

I have been an actor and contributor in numerous instances, in the presence of clients or not, in order to capture needs and provide a targeted response of quality.
