I'm a passionate Linux System Administrator with over 3 years of hands-on experience managing, automating, and optimizing Linux-based infrastructures.
Currently transitioning into the Site Reliability Engineering (SRE) domain — focusing on automation, reliability, and observability in production systems.

• 💻 Linux Administration — System hardening, SELinux, user/group management, systemd, crontab, log rotation, and boot optimization
• 🔐 Networking & Security — IPTables/nftables, SSH hardening, VPN tunnels, TLS/SSL, DNS & DHCP configuration
• ⚙️ Automation & Infrastructure as Code (IaC) — Ansible playbooks, Bash scripting, GitHub Actions, CI/CD pipeline automation
• 📦 Containerization — Docker image build, registry management, multi-container orchestration, Trivy vulnerability scanning
• ☁️ CI/CD & Build Pipelines — Jenkins setup, webhooks, SonarQube code quality analysis, OWASP dependency check, Trivy integration
• 📊 Monitoring & Observability — Prometheus, Grafana, Node Exporter, Alertmanager rules, log shipping with Filebeat & Logstash
• 🧩 SRE Concepts — SLI/SLO/SLAs, error budgets, service reliability metrics, incident response, auto-remediation triggers
• 🧱 Private Infrastructure Work — LTE/SIP server integration, FreePBX, Openfire, Jitsi, and EPC-based internal communication networks

• Learning Kubernetes internals, Pods, Services, Ingress, Deployments, and Helm
• Exploring Service Meshes like Istio and Linkerd for observability and traffic control
• Improving Infrastructure Monitoring with custom Prometheus exporters
• Implementing self-healing CI/CD pipelines and alert-driven automation
• Designing end-to-end DevOps lab integrating Jenkins, SonarQube, Trivy, Prometheus, and Grafana

"I believe in learning by building — every configuration, every automation, every issue teaches me something new."
