About Arthur

Currently training for a Master's degree in Infrastructure and Cybersecurity Systems Management, I wish to put my technical skills to the service of companies in parallel with my studies, during my free time.

With a background focused on systems & networks infrastructure, cybersecurity, and IT support, I work on various IT projects, from design to implementation, including securing and monitoring environments.

I assist companies in:
  • designing and evolving their IT infrastructures
  • securing systems and access (best practices, risk prevention)
  • implementing supervision and monitoring tools
  • optimizing networks, workstations, and IT services
  • providing technical assistance and advice tailored to business needs
Rigorous, pedagogical, and solution-oriented, I favor reliable, secure, and scalable projects, with a pragmatic approach adapted to the constraints of each organization.

👉 Available for one-off missions, consulting, or project support, remotely.
