AWS Cloud Engineer, DevOps Engineer and Linux (RHEL) System Administrator with 5+ years of experience in production AWS and hybrid infrastructure. The core work covers EC2, ECS Fargate, Docker, Terraform (Infrastructure as Code), VPC, IAM, Load Balancing, Auto Scaling, CI/CD, Monitoring & Observability, Security, Incident Management and Disaster Recovery. Currently responsible for 2,000+ production servers across 20+ client environments, kept at 99.9% uptime.

Provisioning, patching, monitoring and backups are automated with Terraform, Ansible, Bash, Python, AWS Lambda, Jenkins, GitHub Actions and AWS CodePipeline, which cut setup and admin effort by 60–80%. Certified as AWS Solutions Architect – Associate and Red Hat Certified System Administrator (RHCSA).

Linux Administrator (AWS & DevOps) at Skilrock Technologies Pvt. Ltd. (2021-07 – Present)

• Administered production Linux servers (RHEL, Ubuntu, CentOS) running Apache, Nginx, Tomcat and MySQL, covering 2,000+ servers across 20+ client environments, with uptime, security compliance and performance as the main targets.
• Set up a centralized monitoring and observability platform with Zabbix, Prometheus, Grafana, Datadog, Nagios and AWS CloudWatch, using custom templates and alerting policies. This is what holds uptime at 99.9%.
• Rolled out Zabbix Server, Agents and Proxy across several environments for both centralized and distributed monitoring.
• Configured Prometheus exporters, alerting rules and Grafana dashboards to track CPU, memory, disk, JVM, MySQL, network, TCP/UDP, ICMP, DNS and SNMP metrics.
• Built ELK Stack pipelines for centralized log collection and analysis, so incidents are spotted earlier and production issues take less time to troubleshoot.
• Automated Zabbix server and agent deployment with Ansible, bringing setup down from several hours to about 15 minutes (80% faster).
• Built an automated backup system that sends Telegram alerts, which cut backup review time by 75%.
• Wrote Ansible playbooks for user management, OS patching and configuration, reducing admin time by 60%.
• Automated observability deployment, configuration, health checks and maintenance with Ansible and Bash, cutting manual configuration and troubleshooting errors by 50%+.
• Provided 24/7 L1/L2 production support for applications, APIs, databases and infrastructure on international Lottery Management Systems, payment gateways and gaming platforms (Nigeria, Zimbabwe, Ghana). Handled P1/P2 incident response by correlating logs and alerts across ELK, Grafana, Zabbix and CloudWatch.
• Supported CI/CD deployments (Jenkins, GitLab, GitHub Actions): pre-checks, deployment monitoring, rollback and validation after each production release.
• Designed and deployed scalable, fault-tolerant and secure AWS setups on EC2, ECS Fargate, EBS, S3, RDS, ELB, Auto Scaling, Lambda and DynamoDB.
• Architected AWS EC2 deployments on RHEL with LVM partitioning and performance tuning.
• Automated AWS provisioning with reusable Terraform modules across multiple environments, using variables, outputs, data sources and providers. Every change went through a terraform plan review before apply, with dependencies, remote state, state locking and workspaces managed in code and Git/GitHub for version control. Manual errors dropped by 70%.
• Applied IaC security best practices in Terraform, including least-privilege IAM policies, RBAC, secrets management and compliance controls.
• Deployed containerized web applications on Amazon ECS with AWS Fargate behind an ALB across multiple Availability Zones. Images are stored in private ECR repositories, scaling uses Target Tracking Auto Scaling, and database credentials come from Secrets Manager through IAM task roles, with Lambda-based credential rotation for RDS (MySQL).
• Provisioned and troubleshot EC2 instances and AWS networking (VPCs, subnets, route tables, security groups, network ACLs, internet/NAT gateways, ALB/NLB/ELB), including cloud connectivity issues.
• Set up CloudWatch and SNS monitoring and notifications, designed secured VPCs, and defined IAM users, roles and policies to strengthen security posture.
• Configured Route 53, ACM and CloudFront for DNS, HTTPS/SSL-TLS and content delivery across 10+ domains and certificates, and maintained SSL certificates on Nginx, Apache, Tomcat and AWS ELB.
• Automated EC2 start/stop on a schedule with AWS Lambda, reducing non-production compute costs by about 40%.
• Built a CI/CD pipeline (Jenkins, Docker, Ansible) that builds, tags and deploys Docker images whenever code is pushed to GitHub, with Git version control for application code, playbooks and pipeline configurations.
• Supported a three-tier AWS architecture, configuring the ALB and target groups to spread HTTPS traffic across Apache/Tomcat EC2 instances.
• Resolved L1-escalated incidents, service requests and changes across AWS dev, staging and production environments.
• Ran post-patching validation and supported infrastructure upgrades, migrations, backup/disaster recovery, hybrid on-premises/AWS integration and 24/7 on-call, with Root Cause Analysis (RCA) for recurring incidents.
