Red Hat Linux administrator (RHEL 7/8/9) with AWS SysOps certification and Terraform (Infrastructure as Code) expertise. I build repeatable, version-controlled AWS environments. SELinux enforcing. LVM. Ansible automation. I am an AWS-certified engineer with Terraform expertise and deep Red Hat Linux administration skills. I have managed 50+ RHEL/CentOS servers in production for the last 4 years. My approach: Infrastructure as Code first (Terraform), automation second (Ansible), security always (SELinux enforcing). What I do for clients: Terraform (Infrastructure as Code) AWS infrastructure provisioning (EC2, VPC, subnets, security groups, IAM, S3, RDS, ALB/NLB) Remote state management (S3 backend + DynamoDB locking) Modules for reusable infrastructure components Terraform + Ansible integration (provisioners, remote-exec, or separate workflows) State migration and refactoring CI/CD ready configurations (GitHub Actions friendly) Red Hat Linux Administration (RHEL / CentOS / AlmaLinux) Installation and configuration (Kickstart, manual, or Terraform-provisioned) LVM management (create, extend, reduce filesystems) SELinux troubleshooting and custom policy modules (enforcing mode only) Firewalld configuration (zones, rich rules, masquerading) SSH hardening (key auth, disable root, port changes) Systemd service management and custom unit files Kernel tuning (sysctl) and performance optimization Log management (rsyslog, journald, logrotate) AWS Cloud Engineering EC2 instance provisioning (Linux/Windows) via Terraform and manual VPC design (subnets, route tables, NAT gateways, peering, Transit Gateway) IAM policies, roles, and least-privilege access Systems Manager (SSM) for patching and automation CloudWatch monitoring and alarming Auto Scaling and Load Balancers (ALB/NLB) S3 storage with lifecycle policies, versioning, and replication Multi-account Organization setup Automation & Configuration Management Terraform for AWS provisioning (HCL, modules, state management) Ansible for post-provisioning config (playbooks, roles, Jinja2) Packer (basic) for custom AMIs (available if needed) Bash scripting for custom automation Monitoring & Logging Graylog setup (rsyslog forwarding, dashboards) Nagios / Checkmk configuration CloudWatch agent + custom metrics Recent project examples: Wrote Terraform modules to deploy production-ready VPC with public/private subnets, NAT gateway, ALB, and Auto Scaling group of RHEL 8 instances. Integrated with Ansible for post-deploy configuration. Managed 50+ RHEL 8 servers including SELinux enforcement, Firewalld rules, LVM resizing, and monthly patching via Ansible. Migrated Terraform state from local to S3 backend with DynamoDB locking for team collaboration. Migrated VMware vCenter 6 → 7 and redesigned network with 5 VLANs and new IP scheme. Why work with me: AWS SysOps Certified (hands-on, not just theory) Terraform production experience (state management, modules, S3 backend) Red Hat Linux production experience (SELinux enforcing - I do not disable it) Ansible automation for configuration management Infrastructure as Code philosophy – everything version-controlled, repeatable, documented My typical Terraform + Ansible workflow: Write Terraform to provision AWS resources (VPC, EC2, security groups, IAM) Output EC2 IPs to Ansible inventory Run Ansible playbooks for SELinux, Firewalld, users, packages Commit everything to GitHub (client access provided) I am available for: Ongoing retainer (weekly hours) One-time projects (Terraform module creation, AWS environment setup) Terraform state troubleshooting and migration Emergency infrastructure fixes Message me with: What AWS services you need provisioned If you have existing Terraform code or need from scratch What Linux distribution and version you are using
