Contributed to the design, implementation, and operation of federated monitoring pipelines to support Carrefour’s large-scale retail infrastructure across GCP, Azure, and on-premise infrastructure . Ensured high observability by integrating diverse metrics into unified dashboards and alerting systems. ● Built and maintained federated pipelines forwarding monitoring data to Elastic, InfluxDB, and VictoriaMetrics. ● Transformed and enriched network, infrastructure, application, and log metrics to support cross-domain dashboarding. ● Ensured high availability and reliability of monitoring infrastructure deployed on GCP ● Developed a centralized alerting system to detect anomalies and reduce incident response time. ● Collaborated with teams across the organization to tailor monitoring solutions to business-critical needs. ● Ensured high availability and reliability of the monitoring infrastructure in cloud environments. ● Documented internal monitoring processes and contributed to knowledge sharing and compliance. ● Continuously evaluated and improved tooling and practices by staying up to date with industry trends.

Contributed and Delivered monitoring-as-a-service solutions to internal project teams, enabling observability and alerting across a wide range of platforms and environments. ● Deployed and configured Prometheus exporters for databases (PostgreSQL, MySQL, SQL Server, MongoDB, Oracle, Redis), Kubernetes clusters, and Linux/Windows nodes. ● Developed reusable GitLab CI/CD templates to provide monitoring stacks as a service, accelerating project onboarding. ● Built and customized Helm charts to meet diverse business requirements across multiple project teams. ● Performed security analysis (SAST) on Docker images, ensuring exporter containers were free from critical vulnerabilities. ● Configured AlertManager for alert routing and filtering, tailored to project-specific thresholds and escalation policies. ● Implemented Prometheus federation and centralized routing to enable multi-tenant observability across environments. ● Delivered QoS and SLA metric dashboards for business stakeholders to monitor uptime and performance guarantees. ● Led version upgrades and maintenance of the monitoring stack with zero downtime for service owners. ● Provided L3-level engineering support for L1/L2 teams and acted as a key contact for escalations and solution design.

Managed and provisioned cloud infrastructure across GCP and Azure, supporting enterprise clients including Carrefour (VPOD project) with reliable, automated, and cost-efficient cloud operations. ● Provisioned and managed multi-tenant environments in Google Cloud Platform (GCP) and Microsoft Azure, handling project creation, IAM/RBAC, and resource scoping. ● Built and maintained cloud infrastructure for customers, including compute, networking, and storage components. ● Implemented automated VM start/stop workflows based on usage tags and cold-down policies, optimizing cost during off-hours without service disruption. ● Developed auto-scaling strategies to ensure service stability during high-load periods while minimizing over-provisioning. ● Configured network access controls and role-based access (RBAC) to secure infrastructure and enforce least-privilege principles. ● Supported day-to-day GCP operations including quota management, billing alerts, identity setup, and troubleshooting deployment issues. ● Participated in platform lifecycle management for infrastructure, ensuring operational availability and cost visibility.
