Designed and implemented automated deployment systems and time optimized CI/CD pipelines for multiple clients. Designed and implemented Kubernetes-based architectures tailored to project and client requirements. Managed Kubernetes clusters and various Operators and Add-ons applications to get a strong and complete cluster ready for production needs and workload Deployed backup and monitoring solutions (Ansible/AWX, Grafana, Prometheus) to ensure reliability. Adopted a GitOps approach with ArgoCD, streamlining releases and improving consistency for our projects. Set up centralized logging and tracing systems to strengthen observability and compliance using Loki , Tempo and Fluentbit Stack.

managed the Azure infrastructure for the Mobile E-Commerce application : Marjane Mall Implemented secure and automated deployments using Azure DevOps Pipelines and Github. Optimized resource allocation and scaling policies to align with workload demands. Implemented cost monitoring and alerting azure native system using Azure Cost Management and Azure serverless functions. Migrated and restructured services to leverage serverless and PaaS solutions for better efficiency and lower operational overhead.

During this project, I deployed and automated multiple CI/CD pipelines while integrating various tools and technologies: Deployed several CI/CD pipelines on GitLab CI using GitLab Runners on Azure. Integrated unit tests, SAST (SonarQube, Trivy), and API testing (Postman). Containerized applications with Docker and automated Docker image versioning through Python scripts. Provisioned Azure infrastructure via Terraform (including an AKS cluster) and automated resource configuration with Ansible. Implemented monitoring with Prometheus and Grafana, and automated Kubernetes manifest updates. Enabled continuous deployment with ArgoCD (GitOps).

During this project, I was responsible for several technical aspects, from design to deployment of the application: Designed and developed a full-stack application using Spring Boot (backend), Vue.js (frontend), and an integrated database. Implemented a CI/CD pipeline on Jenkins, including automated testing with Postman and Mocha.js, and containerization with Docker. Deployed the application on Azure Web App using Terraform.

Implemented a CI/CD pipeline on GitLab CI for a web solution. Automated code quality and testing using SonarQube. Containerized the application with Docker and orchestrated it using Kubernetes. Deployed the solution on AWS EKS leveraging Terraform for Infrastructure as Code.
