I build, operate, automate, and troubleshoot cloud and Linux infrastructure with a focus on reliability, security, observability, and repeatable deployments.

My hands-on experience spans cloud infrastructure, Linux systems administration, CI/CD, containers, Kubernetes, infrastructure automation, monitoring, networking, and security across AWS, Microsoft Azure, and Google Cloud.

• ☁️ Multi-cloud infrastructure across AWS, Azure & GCP
• 🖥️ 50+ Linux & Windows servers administered
• 🔄 CI/CD with Jenkins & GitHub Actions
• 📊 Prometheus & Grafana observability
• 🐳 Docker & Kubernetes workloads
• ⚙️ Bash-based automation and service remediation
• 🔐 Infrastructure security, IAM, SSL/TLS, DNS & firewalls

Practical observability architecture for Linux hosts and Docker workloads using:

• Grafana Alloy
• cAdvisor
• Prometheus-compatible metrics
• Grafana
• Loki-based container log collection
