DevSecOps intern at B&B Industrial Systems Management who deployed a three-control-plane Kubernetes cluster with 99.9% availability.
TunisiaWhat I'm looking for
At B&B Industrial Systems Management, I deployed a high-availability Kubernetes cluster with three control-plane nodes using kubeadm, achieving 99.9% availability.
I also set up Nginx load balancing with rate limiting and DDoS protection. I designed a Zero Trust architecture using eBPF and Calico for granular traffic control.
During my summer internship at B&B Industrial Systems Management, I designed and deployed secure network access using X.509 certificates and 802.1X/EAP-TLS. I automated certificate lifecycle management with Ansible and CI/CD.
At Laboratoire de Technologie et d’Imagerie Médicale, I designed a cloud-connected data acquisition system for real-time analysis, deployed Amazon EC2 instances, and used Amazon S3 for storage and archiving. I also developed a Java mobile application for data visualization.
