About

With nearly a decade in the IT industry, including 4 years in DevOps, my journey has spanned system administration, VoIP engineering, and cloud engineering. This diverse background enables me to create efficient, secure, and scalable services. Currently, I'm enhancing my skills in Golang to bridge into software development. My technical toolkit includes expertise in: - Virtualization & Containerization: AWS, Docker, Kubernetes, EKS - Linux Systems: Comprehensive management across various distributions - Infrastructure as Code & Automation: Golang, Ansible, Terragrunt/Terraform - CI/CD Processes: Proficiency with GitLab, GitHub, ArgoCD - Monitoring & Observability: Basics of Grafana, Prometheus, ELK - Networking & VoIP Passionate about continuous learning, I'm keen on applying my expanding Golang knowledge to further innovate and drive efficiency in digital environments.
