• Infrastructure Resilience: Maintained 99.9% system uptime across a mission-critical on-premise stack (VMware, Kubernetes, Docker) by managing high-availability configurations and executing seamless, zero-downtime updates. • CI/CD Optimization & Velocity: Engineered automated GitLab CI/CD pipelines that reduced average deployment latency by 85% (from 2 hours to 15 minutes), significantly accelerating the software development lifecycle. • Developer Enablement & Technical Documentation: Partnered closely with development teams to streamline the SDLC; authored comprehensive technical documentation and runbooks to standardize deployment procedures and reduce onboarding friction. • DevSecOps & Full-Stack Observability: Integrated SonarQube for automated security scanning and established a comprehensive monitoring/logging suite (Prometheus, Grafana, Loki, Fluent Bit) to enforce Quality Gates and drastically reduce Mean Time to Detection (MTTD). • Hybrid Cloud Orchestration: Orchestrated complex multi-service deployments (Redis, Elasticsearch, HA Kafka) utilizing kubeadm for Dev/Test and a private AKS cluster on Azure Stack Hub for Production.

• Production-Grade Cluster Deployment: Architected and provisioned a highly available 8-node kubeadm Kubernetes cluster on VMware ESXi, which continues to serve as the core infrastructure for Production and Staging environments. • Secured DevOps Toolchain: Established the company’s foundational CI/CD ecosystem by integrating GitLab, Harbor, and SonarQube, secured via NGINX Reverse Proxy and SSL/TLS encryption.

• setting up a CI/CD Pipeline using Jenkins and Kubernetes. the pipeline is automatically triggered by new git commits launching the steps defined in the Jenkins file (compilation, test, deployment, etc.). • Deploying the containerized application to the Kubernetes cluster.

• contribution to the creation of the a website that the company is developing to manage its staff and trainees, using ANGULAR.
