Featured DevOps Achievements

🤖 Multi-Stage Automated Git-to-EC2 CI/CD Pipeline
GitHub Actions, Docker, AWS EC2, Linux Systemd
  • Engineered a fully automated continuous integration and delivery pipeline triggered seamlessly upon code commits.
  • Automated multi-stage Docker builds to compile application images, tag them dynamically, and securely publish to Docker Hub.
  • Configured remote automation runners to target AWS London EC2 instances via secure alternative ports (Port 2222), execute system cleanups, pull production-ready container images, and bind host interfaces securely.
  • Designed systemd microservice configuration rules to cleanly release OS ports and allow containerized servers to safely claim resource interfaces on the host network.
⚙️ Infrastructure as Code (IaC) AWS Environment Deployment
Terraform, AWS, Secure VPC Networking
  • Created declarative Terraform configurations to construct robust virtual topologies, including custom VPCs, secure subnets, and internet gateways.
  • Formulated dynamic Security Group network ingress and egress firewall rule sets, minimizing exposure risk to host systems while maintaining high application availability.
