Presentation

For the past 10 years, I’ve worked with information systems, each with its own specific needs: a government ministry, the pharmaceutical industry, luxury goods, IT outsourcing, and a CAC 40 company. Each has its own constraints, pace, and challenges. I’ve learned that understanding how a business works before securing its IT systems is essential.

Specifically, I can help you:
- migrate, modernize, or overhaul an aging IT fleet and infrastructure;
- keep your information system up to date and secure over time;
- get real value from Tanium (visibility, compliance, incident response) instead of using only 20% of its capabilities;
- provide level 2/3 user support to free up your internal team’s time;
- for individuals: provide advice and troubleshoot all kinds of computer issues.

My approach to collaboration is characterized by transparency, attentive listening, and seeing things through to understand the real need rather than offering solutions that only look good on paper.

If this sounds right for you, get in touch.
