1. Linux Server Administration:  
  - Manage, monitor, and maintain Linux-based servers (e.g., Almalinux , Ubuntu, RHEL) in production environments.  
  - Perform server provisioning, patching, performance tuning, and troubleshooting for enterprise-grade applications.

2. Hosting & Web Services:  
  - Set up, configure, and maintain hosting environments using tools like cPanel, WHM, Plesk, Apache, and Nginx.  
  - Manage DNS configurations, SSL certificate installations, and troubleshoot hosting-related issues for clients or applications.

3. Load Balancing:  
  - Deploy, configure, and manage load balancing solutions such as HAProxy, NGINX, or AWS Elastic Load Balancer (ELB).  
  - Optimize traffic distribution, maintain high availability, and support large-scale web applications.

4. Database Replication:  
  - Implement and manage database replication solutions for MySQL/MariaDB and PostgreSQL.  
  - Ensure data integrity, availability, and consistency across multiple replicas in high-traffic environments.

5. Clustering:  
  - Design and maintain clusters for high availability and scalability using Proxmox VE or Kubernetes.  
  - Perform resource allocation, live migrations, and implement fault-tolerant configurations for critical systems.

6. AWS S3 Storage Management:  
  - Integrate AWS S3 for data storage, backup, and archival purposes.  
  - Optimize S3 buckets for performance, security (IAM roles, bucket policies), and cost efficiency.

7. Proxmox Virtualization:  
  - Set up and manage virtual environments using Proxmox VE, including cluster management and high availability.  
  - Perform virtual machine (VM) provisioning, monitoring, and disaster recovery planning using Proxmox Backup Server.

8. Monitoring & Optimization:  
  - Utilize monitoring tools like Prometheus, Grafana, or Zabbix to ensure system uptime and health.  
  - Conduct root cause analysis, identify bottlenecks, and improve server and application performance.

9. Backup and Recovery:  
  - Implement automated backup strategies using tools like AWS S3, Proxmox Backup Server, or other solutions.  
  - Regularly test and document disaster recovery plans to minimize downtime during incidents.

10. Security & Compliance:  
   - Apply server hardening practices, including firewalls (e.g., iptables, UFW) and security patch management.  
   - Implement and maintain compliance with security best practices, including data encryption and access controls.
