About Ugo

Do you want reliable, fast, and secure deployments on Kubernetes? 🔐🚀
GitLab CI/CD pipelines integrating security from the first commit?
Automated, compliant, and scalable cloud infrastructure? ☁️

I am a DevSecOps Engineer, specializing in Kubernetes, GitLab CI/CD, Docker, Terraform, and CI/CD pipeline security.
I help teams integrate security into delivery without slowing down production releases.

🔐 What I do concretely

• Design and secure GitLab CI/CD pipelines (SAST, DAST, Docker image scanning, secrets scanning)
• Implement and harden Kubernetes clusters (AKS, EKS, on-prem)
• Containerize and secure Docker images (hardening, attack surface reduction)
• Automate infrastructure with Terraform / Ansible
• Implement observability and security tools 📊
• Secure cloud access, secrets, and identities 🔑

📈 Results achieved with my clients

• Up to -40% build and deployment time
• Secure, stable, and audited CI/CD pipelines
• Reduced production security risks
• Scalable, documented, and maintainable infrastructures

🧠 My DevSecOps approach

Security should not be a hindrance.
I integrate it into pipelines, infrastructure, and team best practices.
Goal: deliver fast, well, and with confidence ⚡

Malt is not a CV.
It's a showcase.

👉 My proposition is simple: be your DevSecOps partner to secure and scale your projects 🚀

We called upon Ugo in a complex technical context, and his intervention was decisive. He quickly understood our challenges, proposed concrete solutions, and got our infrastructure back on track. Beyond his efficiency and responsiveness, he changed our perspective on DevOps: far from being a constraint, it proved to be a real driver of efficiency, rigor, and serenity in our development processes. A collaboration that was as fluid as it was valuable. We highly recommend him!
