About Julien

Part of the generation that grew up with the dawn of the internet, I am a convinced Linux user and an unapologetic geek.

I have been immersed in the world of web hosting for over 10 years, with a particular interest in high availability, scalability, and operational industrialization issues.

After several salaried experiences, I wanted to take the leap to have a broader horizon, to be able to work on more varied projects and technologies.

This very tech-centric universe of web hosting, cloud, and everything that revolves around it is often obscure, misunderstood, and can be intimidating.
So, I set myself the goal of supporting my clients with their business challenges by providing them with tailored solutions.

I work on various aspects of your online services or applications:
🔹 Security: ensuring the integrity of your servers and your application's data
🔹 Availability: enabling optimal use of your service, ensuring fault tolerance
🔹 Performance: guaranteeing optimal service operation, even under heavy load with a controlled budget

With 2 possible intervention modes:
🔹 Project Mode: impactful for your infrastructure, deployment of a new functional component, setting up a high-availability infrastructure, setting up a DRP.
🔹 Managed Services: long-term with a monthly fee for complete server and middleware management, allowing you to focus on the business aspects of your company.

As a member of the OVHCloud partner program, I can advise and support you in choosing and using your products.

I look forward to discussing your projects, feel free to contact me for a personalized quote 🤝.
