With over 17+ years of experience, I've cultivated strong expertise in various technical domains, including mentorship and implementing numerous Proof of Concepts (PoCs). I've taken charge of complete automation projects, from building foundational infrastructure to enabling monitoring with event-driven automation. My hands-on experience extends to emulating labs for research, learning, and conducting root cause analysis for issues faced in customer environments. This, coupled with my commitment to innovation, is evident in spearheading projects that seamlessly integrate IT Service Management (ITSM), streamlining user service requests through meticulously designed automated workflows. In addition, I am a self-learner, adept at swiftly adapting to new technologies. This commitment to continuous learning has been pivotal in my ability to embrace and integrate cutting-edge tools and methodologies. My journey reflects adaptability and continuous learning, crucial traits in embracing modern technologies. Navigating DevOps, cloud technologies, and strategic project management, I consistently synthesize complex solutions and make a meaningful impact in dynamic IT environments. - Containerization: Kubernetes, Docker, Openshift - Automation: Ansible, Ansible Automation Platform, Terraform - Scripting: Bash, Python - CI/CD - GitLab, ArgoCD, Openshift GitOps - Monitoring: Prometheus & Grafana, Nagios, Zabbix - Database: PostgreSQL - Operating Systems: RHEL 7/8, SLES 12/15 - Cloud Computing: GCP, Azure, AWS - Networking: Cisco Routing & Switching - Virtualization: vSphere 5.x/6.x - Management Tasks: Team Management, Technical Recruiting, Mentoring
