Ahmed MELLOULI

• Designed and implemented a highly available (HA) AWS infrastructure for a distributed web application, leveraging Auto Scaling Groups, ELB, and a custom VPC across multiple subnets and Availability Zones. • Achieved 100% infrastructure reproducibility by implementing Terraform for provisioning 15+ core AWS resources, standardizing all environments (dev, staging, prod) via IaC. • Designed and implemented a robust GitLab CI/CD pipeline, orchestrating Terraform remote state management (S3 + DynamoDB) to ensure atomic updates and secure deployment workflows with approval gating. • Established baseline monitoring using AWS CloudWatch to track EC2 health, ELB latency, and resource utilization, ensuring proactive incident response.

• Design of CI/CD pipelines with Jenkins to automate builds, testing, and code analysis. • Implementation of a GitOps approach to automate Kubernetes deployments using ArgoCD and Kustomize. • Deployment of applications across multiple environments/namespaces within the Kubernetes cluster. • Development of analytical features and advanced visualizations with ReactJS, allowing users to create profiles, share experiences, and filter plants by multiple traits via interactive histograms. • Integration of Google Analytics for user behavior tracking and analysis. • Creation of an interface for visualizing quality reports from an internal application, secured via Keycloak. Tools: AWS, Kubernetes, Docker, ArgoCD, Kustomize, Jenkins, SonarQube, HTML/CSS, ReactJS, Ruby on Rails, ExpressJS, PostgreSQL, Google Analytics

• Automation of builds, tests, and deployments on Kubernetes via GitLab CI, with SonarQube integration for code quality. • Management and maintenance of key Kubernetes resources such as Deployments, Services, ConfigMaps, and Ingress, while optimizing cluster resource limits. • Standardization of quality processes through continuous code reviews and CI practices for production deployments. • Standardization of deployments on Kubernetes clusters through the use of Helm charts. • Development of the BEFOOT website, including the administrator portal and interfaces for stadium owners and customers. Tools: Docker, Jenkins, SonarQube, Nexus, Docker-compose, AWS, Helm, HTML/CSS, Angular, SpringBoot, PostgreSQL

• Collaborative team development of interfaces (home page, services, about, career, contact) for the Artibedded startup website, aiming for an optimal user experience. Tools: ReactJS, ExpressJS, HTML/CSS, Typescript, PostgreSQL
