Hi, I'mAbdur Rehman.

Securing CI/CD pipelines, hardening containerized applications, and managing cloud infrastructure at an enterprise scale.

• Secured CI/CD pipeline by implementing SonarQube quality gates, Trivy vulnerability scanning, and Cosign image signing to prevent Docker image tampering; identified 645 code improvements and flagged 15% of findings as security vulnerabilities.
• Hardened containerized AIIT application by rebuilding Docker images on Chainguard base images, eliminating root privilege execution and enforcing CPU/memory resource limits.
• Protected an unsecured internal VPC by deploying a VPN for remote employees and monitoring network traffic with Suricata and Zeek across 8 servers, enabling detection of anomalous activity.
• Configured Active Directory (AD) with role-based access controls to restrict external company users from accessing AIIT internal servers, enforcing least privilege access.
• Managed product release cycles and automated deployments on AWS, ensuring smooth, low-downtime transitions between versions.

Led cloud migration, containerization, and Kubernetes orchestration, establishing observability practices and managing GCP environments.

• Migrated the application from cPanel hosting to AWS Lightsail in 1 day with zero downtime.
• Containerized the full stack application using Docker, reducing application issues to 5%.
• Deployed applications on Kubernetes using production-ready workloads — Deployments, StatefulSets, Services, Ingress Controllers, HPA, and VPA — ensuring scalability and high availability.
• Developed Helm charts to standardize deployments and enable repeatable, consistent releases across environments.
• Implemented monitoring and observability with Prometheus and Grafana for real-time performance tuning; used Loki with Grafana for centralized log monitoring.
• Managed Google Cloud Platform (GCP) infrastructure and deployments for external clients.

Built CI/CD pipelines, deployed containerized workloads on Kubernetes, and engineered Azure cloud infrastructure as an intern.

• Architected and implemented CI/CD pipelines using Jenkins, Docker, and Kubernetes to enable scalable, automated application deployments.
• Deployed a containerized application on Kubernetes using Deployments, Services, and Ingress, ensuring high availability and production readiness.
• Integrated Prometheus and Grafana for monitoring and logging within a Kubernetes environment, enhancing operational visibility.
• Deployed containerized applications on IBM Cloud using IBM Kubernetes Service (IKS) and managed clusters with kubectl.
• Engineered infrastructure as code on Microsoft Azure, including VM deployment, VPN setup, and App Service configuration.
