I am a Senior Linux Engineer with over 15 years of experience in architecting, automating, and optimizing mission-critical deployments in large-scale environments. I thrive on ensuring high availability, performance tuning, and security hardening, using my deep knowledge of open-source tools and modern infrastructure.

• Linux: RedHat, Debian, Ubuntu, OpenBSD (Advanced kernel tuning and system optimization)
• Web & Proxy Servers: Apache, Nginx, HAProxy, Lighttpd (High-performance, secure web infrastructure)
• Virtualization & Containers: Docker, KVM, VMware, Kubernetes (Deploying & managing microservices and VMs at scale)

• Cloud Platforms: AWS, Azure, GCP, OpenStack (Architecting and managing hybrid/multi-cloud environments)
• Infrastructure as Code: Ansible, Terraform, Packer (Full automation for provisioning and configuration management)
• CI/CD: Jenkins, GitLab CI/CD, GitOps (Streamlined DevOps pipelines for efficient code deployment)

• Protocols: TCP/IP, DNS, HTTP, OpenVPN (Advanced routing, load balancing, and troubleshooting)
• Firewalls & VPNs: Iptables, UFW, WireGuard (Deep expertise in network security, VPN setups, and firewall policies)
• Hardening & Compliance: SELinux, AppArmor, auditd (Security hardening based on industry standards like CIS benchmarks)

• Monitoring Tools: Prometheus, Grafana, ELK Stack, Zabbix (Advanced monitoring and alerting for mission-critical systems)
• Performance Tuning: Optimizing systems using sysctl, kernel modules, and disk I/O tuning (Advanced performance optimization strategies)

• Relational Databases: PostgreSQL, MySQL (Replication, clustering, and performance tuning for large-scale databases)
• NoSQL Databases: Redis, MongoDB (High-availability NoSQL implementations and optimizations)
• File Systems: ZFS, Btrfs, Ext4 (Advanced management of high-performance file systems, including snapshots and quotas)

• Team Leadership: Managing cross-functional teams to deliver robust infrastructure solutions and continuous improvement initiatives.
• Mentoring: Training junior engineers and promoting DevOps best practices within teams.
• Project Management: Delivering projects on time, ensuring scalability, security, and performance of mission-critical infrastructure.

• Hybrid Cloud Deployment: Designed and deployed a highly available hybrid cloud infrastructure across AWS and on-premise OpenStack.
• Kubernetes Automation: Built end-to-end Kubernetes clusters using Helm, automated scaling with Ansible, and integrated Prometheus for system health monitoring.
• Database Clustering: Led the implementation of a PostgreSQL HA setup using replication and failover strategies to minimize downtime.
• DevOps Transformation: Played a key role in driving the adoption of DevOps practices, improving automation across the pipeline using GitLab CI and Ansible.

Linux is the backbone of innovation—offering limitless flexibility, performance, and security. As a Senior Linux Engineer, I leverage the power of Linux to create scalable, resilient, and efficient infrastructures that keep critical applications running smoothly.
