• Built new and maintained existing CI/CD pipelines with developed GitHub actions as well as using DevOps tools such as Jenkins, SonarQube, Ansible, GIT, Maven, Docker, Kubernetes, and Open Shift.
• Utilized AWS services to design, deploy, and manage robust and scalable infrastructure, implementing Infrastructure as Code (IAC) principles using tools such as Terraform.
• Manage and enforce IAM policies to control user and system access to cloud resources, following the principle of least privilege.
• Implemented container security practices by regularly scanning container images for vulnerabilities using tools Trivy, Leveraged Kubernetes on AWS to orchestrate containerized workloads, optimizing resource utilization, ensuring high availability, and enabling seamless scaling based on demand.
• Utilized Checkov to assess the security of Infrastructure as Code (IaC) scripts, such as Terraform templates, ensuring compliance with security best practices and organizational policies.
• Implemented automated SSL certificate provisioning and renewal processes using tools like AWS Certificate Manager (ACM) and Let's Encrypt. This reduced manual intervention and eliminated the risk of certificate expiration.
• Designed and implemented Helm charts for containerized applications, making it easier to deploy complex microservices architectures on Amazon EKS and enabling streamlined version-controlled releases.
• Designed and implemented highly available and fault-tolerant AWS architectures using Terraform, leveraging features like auto-scaling groups, Elastic Load Balancers, and Route 53 for seamless application deployments. Created Pipeline Declarative Scripts using Groovy for Jenkins Integration with Maven, Docker, Nexus, and SonarQube.
• Configured continuous monitoring using NewRelic, Prometheus, Grafana, and DataDog.

Successfully migrated on-premise servers from the data center to Amazon Web Services Cloud (PaaS & SaaS),

for PHP and .NET framework and applications and improved

availability and reliability.

Designed AWS infrastructure for 4 applications, including creating and configuring VPC, EC2 instances,

WAF, Load balancing systems, RDS databases, S3 , Route53, SQS, CloudFront CDN, Cloud Watch.

Built continuous integration and deployment pipelines for 20+ services, optimizing release automation,

speeding up deployments by 75%, and improving code accuracy by 30%.

Reduced security incidents by 60% through continuous QA testing and vulnerability management.

Using tools such as Prometheus, and Grafana, we maintain 24-hour operations, monitor all applications, and

ensure 99.9% uptime for the servers.

Installed and managed application servers, backing up data, and server optimization. Designed proactive preventive maintenance schedules to prevent unnecessary downtime and hardware faults. Managed network and system performance, troubleshooting, security patching, and maintenance. Configured and Managed system storage resources, disk utilization, logs alert, and CPU utilization in Dev, Test, and Prod environments. Administered Cron Jobs for process management, server reboot, and disk management. Set up, configured, and troubleshoot TCP/IP, DHCP, and DNS in multiple LANs. Oversaw SSL certificate management for secure communication within the infrastructure. This included procuring, installing, and renewing SSL certificates for internal services. Developed requirements analysis, application assessment, and implementation for LAN software.Provisioned new software and hardware according to internal business and security policies. Performed tests of functionality, security, and performance of different workstations and devices.
