DevSecOps Engineer at Sopra HR Software who cut vulnerability feedback to 8–12 minutes per pipeline run.
TunisiaWhat I'm looking for
At Sopra HR Software, I engineered an eight-stage GitLab CI/CD pipeline that cut vulnerability feedback from days or weeks to 8–12 minutes per run. I added security gates that block releases when tests or quality checks fail, secrets are missing, or critical vulnerabilities are found.
I also integrated HashiCorp Vault for runtime secret injection and deployed a two-node k3s cluster with centralized observability using the ELK Stack, Prometheus, and Grafana. For log analysis, I developed a FastAPI engine that matched 86.7% of 80 test samples, alongside a RAG pipeline that delivered root-cause analysis in 3–5 seconds.
During my earlier internship at Sopra HR Software, I built reusable Jenkins pipelines for dev, test, and production environments and automated server lifecycle operations in Bash. My academic work includes a fault-tolerant private cloud on OpenStack, extended to Azure Kubernetes Service, with an application built using Spring Boot and Angular.
