About Assia

I work on the entire life cycle of payroll and HRIS solutions: implementation, evolutions, migrations, and maintenance in operational condition.

Payroll / HRIS Functional Consultant with 10 years of experience, coming from the field as a former payroll manager, I support companies and software vendors in analyzing and securing payroll and DSN (monthly and event-driven) rules, validating calculations, and adapting tools to business realities.

I have worked in initial deployment contexts, as well as on evolution projects, tool migrations, or taking over struggling existing systems. I act as an interface with all stakeholders: employees, payroll teams, HR, management, IT teams, software vendors, clients, and end-users.

My role involves understanding existing rules, identifying gaps or malfunctions, formalizing functional requirements, securing configurations, and supporting teams until a stable and compliant solution is achieved.

Accustomed to complex environments (Time Management, multi-entities, PSE, sensitive regulatory contexts), I am quickly operational on subjects requiring rigor, coordination, and a deep understanding of payroll issues.

Environments & tools:
Cegid, HR Access, PayFit, SILAE
Power BI, Excel, SQL
