Freelancer profile translated to English.

Description

Does your IT infrastructure need to be secured, optimized, or automated? With over 5 years of operational experience, including three years fully remote internationally, I help you protect your information systems and build robust Cloud architectures.

My dual role as a cybersecurity engineer and co-founder of a digital services company is my main strength: I don't just configure equipment, I understand your business challenges. I integrate your business continuity (BCP/DRP) and compliance requirements to deliver sustainable solutions.

💡My added value:

A hybrid "Builder / Defender" expertise, validated by recognized technical certifications (CEH, eJPTv2, CCNA). I am rigorous, responsive, and perfectly comfortable resolving incidents in critical production environments (L2/L3 support).

🛠️The projects and deliverables I manage for you:

*Defensive Cybersecurity & SOC:Deployment and management of SIEM tools (Wazuh, TheHive, Cortex), incident management, risk mapping, and mitigation plans.

Audit & Security: Vulnerability scans (OpenVAS, Nessus) and penetration tests (Pentest).

*Network & Cloud Architecture:Administration of complex environments (Cisco, Fortinet, pfSense), AWS migration, implementation of Infrastructure as Code (Terraform), and CI/CD pipelines (Docker, Kubernetes, GitLab, Jenkins).

*Automation & AI:Development of custom automation scripts and creation of AI-integrated solutions (in Python or Bash, n8n).

*Algorithmic Trading:Development of complex trading bots, backtesting, and fine-tuning of automated strategies (in Pine Script and MQL5).
