  • MuleSoft | Consultant Mission HR Data Synchronization

    With more than 1200 employees, the client wanted to automate their future employees' onboarding and offboarding processes and keep their data up to date.

    In the different HR solutions available in the market, such as MyHR, Azure AD, Oracle DB, or ServiceNow, the operations were done manually on the platforms with all the inconveniences implied: management complexity, unaligned data, multiple human interventions, time loss, and more.

    By using MuleSoft as middleware between those different platforms, I supported my client in implementing a solution that met these requirements without constraints.

    The project enabled:
    • Automation of manual tasks, saving time for support.
    • Better follow-up and reliability.
    • Control of the user's repository.
    • Automation of notifications and emails.
    • Financial impact by saving user licenses without user duplication.
    • Security by the automatic deactivation and refusal of registration if missing mandatory data.
    • Report of the operation and archive.
