About Ibrahima

IT expert with over 8 years of experience, I support organizations in securing and evolving their information systems by aligning technical, business, and governance challenges.

My background is marked by dual expertise: strategic leadership as a former IT Department Head and in-depth technical mastery of critical multi-site infrastructures.

My areas of intervention:

- Governance & Security: Implementation of security policies (ISMS), audits, and ISO 27001 compliance.

- Management & Strategy: Leading technical teams (up to 6 employees), managing OPEX/CAPEX budgets, and cost optimization (30% reduction in maintenance costs observed).

- Project Management: Leading complex deployments (secure LAN, SD-WAN, SOC/NOC, multi-site Wi-Fi) for demanding sectors like Banking and Telecoms.

- Technical Expertise: Fortinet, Cisco, Palo Alto, F5 BIG-IP, VMware, and backup solutions (Veeam).

Certified ISO 27001 Lead Auditor and ITIL V4, my priority is to ensure high availability, performance, and resilience of IT services for the benefit of business strategy.
