VERIZON USA
October 2020 - Present
- Implemented and managed the continuous integration and continuous Deployment procedures. Performed build activities using Maven, Jenkins tools and Github actions. Coordinated/assisted developers with establishing and applying appropriate branching, labeling/naming conventions using GIT source control. Setup for Apache and Nginx webservers coupled with AWS/Azure ELB SSL for all HTTP to HTTPS thereby maximizing security for about 40% Configured Security groups and locked them down to the various authorized subnets and IP addresses in AWS/Azure. Analyzed and resolved conflicts related to merging of source code for GIT Resolved merging issues during rebasing and re-integrating branches by conducting meetings with Development Team Leads to foster collaboration. Deployed applications into an EKS/AKS cluster rather than self-managed k8s clusters using kubeadm or KOPS. Supported and developed tools for integration, automated testing and release management. Experience with container-based deployments using Docker, working with Docker images, Docker hub, and Docker registries, and configuring EKS/AKS clusters using Terraform. Used Helm to simplify code writing to handle complex application deployment integrated with Jenkins. Created custom mode VPCs in AWS/Azure with multi-regional private and public subnets along with firewall rules to allow SSH, ICMP, and RDP ingress traffic. Configured bastion hosts to securely connect to instances running in our private subnet on AWS/Azure. Architected and implemented continuous integration and deployment pipelines using Jenkins. Performed package management, upgrades/patches, troubleshooting, maintenance, and monitoring of applications using Prometheus and Grafana. Created, managed, and administered user accounts security and SSH password-less login. Network configuration & troubleshoot issues with respect to network and configuration files. Wrote inventory and manifest files, ansible playbooks, terraform manifest files and Kubernetes manifest files. Wrote terraform manifest yaml files to provision infrastructure with EKS/AKS clusters, EC2 instances, IAM roles, VPC's, S3 bucket, and other resources on AWS//Azure. Automated AWS/ /Azure cloud deployments using Shell script, Jenkins and Ansible. Set up maintenance scripts using metadata for graceful startup and shutdown of servers. Used Jira to track vulnerabilities, requests, and incidents, and confluence for documentation. Set quality gate policies on SonarQube for code coverages, to track bugs, vulnerabilities and failed the Jenkins pipeline when the threshold was not met. Used Helm charts to deploy Prometheus and Grafana for monitoring. Configured namespaces, RBAC, HPA, and Cluster RBAC, resource quotas for different Kubernetes environments. I have a proven track record of delivering cutting-edge solutions through collaborative software development and meticulous quality assurance, showcasing my expertise in project management and relationship management within enterprise environments. Successfully designed and implemented AWS CDK infrastructure, SQS, SNS, and other middleware services, to enhance system scalability and reliability in a cloud-native environment. Created Ansible playbooks for installation, patching, configuration of servers, user management, with different levels of access, file management, deployment and full automation.

- Collaborated closely with various development teams, providing support and assistance in their deployment activities. Gained valuable experience in applying industry best practices in Cloud Security, conducting audits, and implementing effective security controls. Implemented security best practices in AWS /Azure, including the establishment of multi-factor authentication, access key rotation, encryption, and configuring security measures such as firewalls (security groups), network ACLs (NACLs), and S3 bucket policies. Worked alongside multiple project managers, understanding their release plans, and offering support tailored to their specific requirements. Engaged with development teams to gather the necessary requirements for the application release process of new applications. Conducted thorough analysis of cloud infrastructures, identifying areas for improvement to enhance performance and achieve cost-efficiency. Established VPC peering connections with other accounts, enabling access and routing to services and users across separate accounts. Performed installations, upgrades/patches, troubleshooting, maintenance, and monitoring of Linux servers for various applications. Developed AWS /Azure Launch Templates based on customized Amazon Machine Images (AMIs) and utilized them effectively to configure auto-scaling groups. Utilized Terraform for streamlined configuration, provisioning, and management of infrastructure. Provisioned multi-regional Virtual Private Clouds (VPCs) with both private and public subnets on the AWS /Azure platform. Took responsibility for building, managing, and optimizing Kubernetes deployments, volumes, and replicas throughout the entire software development life-cycle. I have demonstrated proficiency in content management systems (CMS), utilizing cloud infrastructure to drive efficient consulting services and streamline enterprise-wide processes, ensuring seamless application deployment and enhanced user experiences. As a seasoned professional, I am adept in navigating complex data landscapes, utilizing cloud technologies to engineer robust solutions that leverage analytics and ensure optimal performance across a diverse range of products I ensured seamless integration through RESTful API development while maintaining compliance with industry standards and optimizing the development process with Code Pipeline Leveraged design expertise to optimize data flow, driving efficiency and successful outcomes in a dynamic market environment
