About Gillian

Always passionate about IT, I have built my career around systems and network administration and IT support. Thanks to varied experiences in France and Switzerland, I have acquired solid expertise ranging from support to complete administration of IT infrastructures.

I have worked for IT service providers, municipal administrations, universities, and private companies, which has allowed me to develop great versatility and strong adaptability. My role has often combined ticketing and hotline management, server monitoring and maintenance, security alert management, and the implementation of new services.

Alongside IT infrastructure, I have also developed skills in website creation and maintenance (WordPress, Wix, Figma) as well as in digital content creation (Photoshop, Premiere Pro, After Effects, Lightroom). This dual technical and creative background allows me to support both IT missions and digital communication projects.

Today, as a freelancer, I offer reliable, rigorous, and solution-oriented support, whether for user support, systems/networks administration, or digital creation.
