welcome

Opayra is the company behind Thierry Vergult.

I'm a seasoned freelance consultant, and not only an Oracle Payroll expert.

I'm working on projects in Europe and Africa, preferably combining some of the domains of expertise below :

  • project management
  • technical development, mainly with Oracle tools and web development
  • functional design within the HR & Payroll domain
  • data visualisations
