DevSecOps & Cloud Consultant, I specialize in the design, automation, and security of modern infrastructures. My dual expertise in DevOps and offensive cybersecurity allows me to bring a comprehensive vision to build solutions that are both high-performing and robust.
I can undertake specific missions to:
▪ Automate your Infrastructure (IaC) & Cloud: Deploy scalable and reproducible platforms with Terraform and fine-tune configuration with Ansible.
▪ Implement secure CI/CD pipelines: Integrate security scans (SAST, DAST) and manage secrets in your GitLab CI pipelines for a concrete DevSecOps approach.
▪ Audit and secure your environments: Identify and exploit vulnerabilities on Active Directory infrastructures (AD Pentest) and web applications (SQLi, XSS).
Passionate and methodical, I transform complex needs into reliable and documented technical solutions. Feel free to contact me to discuss your projects.
