About Raphael

With over 4 years of experience in human resources and HRIS (Human Resources Information Systems), I assist companies in configuring, migrating, and optimizing their data, payroll, and HR management tools.

At Groupe CEGI, I provided consulting and training to clients across France (Payroll, DSN, Time & Attendance, HR Performance Management, Daily Sick Leave Allowances) in Run & Build mode: Configuring HRIS software (Paye First/Next, DSN First/Next, GEPP Next, Ega Pro, Engagement retraite, SIJ) and migrating data between old and new HR systems using Python.

My background has also given me solid operational experience: HR change management at SNCF Réseau (Digitalization of processes, data migration, integration and training of 100+ employees, creation of Power BI dashboards), as well as recruitment and payroll management at Kangourou Kids.

In parallel, I've been an entrepreneur for 1 year (Place2MeetU — over 300 events and 5000 participants), which taught me to manage a project from start to finish, be proactive, and work autonomously.

What I can bring to your projects:

HRIS Configuration and Migration (Payroll, DSN, Time & Attendance, HR Performance Management)
User Consulting and Training (Run & Build mode)
HR Data Migration (Python scripts)
Reporting and Dashboards (Power BI, Excel)
Recruitment and Payroll Administration

Graduated with a Master's in HRM & Labor Relations (Panthéon-Assas / Panthéon-Sorbonne). Rigorous, autonomous, results-oriented.

Other areas of expertise:

- AI Training — Performance, productivity...
In-depth knowledge of new artificial intelligence tools and systems applied to performance and productivity...

- Save the Date & Event Websites
Creation of Save the Dates and websites for weddings, Bar Mitzvahs, baby showers, parties, and other private events.
