Design and deployment of a prototype SRE platform to centralize the management and monitoring of hybrid Dockerized environments on Microsoft Azure. The solution is automated using Terraform and Ansible, with GitLab CI/CD pipelines, Azure Container Registry (ACR), an Azure Kubernetes Service (AKS) cluster, Prometheus/Grafana observability, centralized logging with the ELK Stack, and alerting through Microsoft Teams and email. An AI-powered chatbot was also integrated to assist with infrastructure troubleshooting and provide guidance for resolving common operational issues.

Designed and developed a web application using Spring Boot and Angular to support the management and operations of Attijari Bank branches. Containerized the application using Docker and deployed it on a Kubernetes cluster using Docker Desktop. Implemented a GitLab CI/CD pipeline for automated build, testing, containerization, and deployment, with Argo CD for GitOps-based continuous delivery. Set up an observability and monitoring stack using Prometheus and Grafana for infrastructure and application monitoring, along with the ELK Stack for centralized log collection, analysis, and visualization.

Configured and administered a Fortinet FortiGate 60E firewall to secure and manage network infrastructure. Implemented and managed firewall policies, NAT rules, routing, network interfaces, VLANs, and access control rules. Participated in network security configuration, traffic filtering, and connectivity troubleshooting. Monitored network traffic and analyzed firewall logs to identify and resolve connectivity and security-related issues.

Designed and developed a smart greenhouse management system combining a Flutter mobile application with an IoT-based greenhouse prototype. Developed the mobile application using Flutter and Firebase, enabling real-time monitoring and remote control of the greenhouse. Designed and implemented the greenhouse prototype using ESP32 and Raspberry Pi, integrating various sensors and actuators to collect environmental data and control greenhouse equipment. Implemented communication between the IoT devices and the mobile application, enabling centralized monitoring and control of parameters such as temperature, humidity, soil moisture, and lighting. Developed automation mechanisms based on collected sensor data to automatically manage greenhouse operations and maintain optimal growing conditions.

Designed and developed a full-stack web application for car rental management using ASP.NET Core and Angular. Implemented a layered and modular architecture following RESTful API principles, with Entity Framework Core for database access and SQL Server for data persistence. Developed core features including vehicle management, customer management, rental reservations, availability tracking, and rental operations. Implemented secure authentication and authorization using JWT, with role-based access control. Applied software engineering best practices including SOLID principles, dependency injection, DTOs, repository/service patterns, input validation, exception handling, and API documentation with Swagger/OpenAPI.
