● Built and configured a virtual data center in the AWS Cloud to support Enterprise Data Warehouse hosting including Virtual Private Cloud (VPC), Public and Private Subnets, Security Groups (SG), Route Tables, Elastic Load Balancers ELB), Route 53.● Advised and implemented the hosting of company applications within the Private Subnet and access to those applications is done with the help of bastion host.● Partook in disaster recovery scenarios for backing up data and utilizing AWS backup and restore tools like AWS storage gateway and developed solutions around pilot light and warm standby.● Built servers using AWS, importing volumes, launching EC2, RDS, creating SG, auto-scaling, ELBs in the defined VPC.● Established VPC connectivity by making use of Transit Gateway for connecting VPCs and VPN connection to a datacenter.● Automated Compliance Governance by provisioning and leveraging AWS Landing Zone as well as AWS Control Tower for centralized enterprise architecture and centralized managing.● Recommended AWS SSO on Control Tower for managing user access on multiple platforms, using CloudWatch, and VPC Flow Logs to monitor and retain account activity related to actions across AWS infrastructure.● Maintenance and support of our CI/CD Pipelines running on ECS.● Used Jenkins as a continuous integration tool for automation of our daily processes.● Built Kubernetes Clusters on AWS with route53 from scratch.● Broke a monolith application into microservices on AWS.● Proposed and developed solutions for application deployments by making use of AWS code pipelines as compared to native tools for cost management Worked on a Database Migration Project from the client's data center to Amazon Aurora.● Provision of serverless resources with lambda functions.

● Used Terraform to provision resources on AWS. Developed modules for different cloud resources for security best practices and standards across accounts.● Used Prometheus and Grafana for monitoring our Kubernetes Cluster running on EKS.● Setup Kubernetes clusters using Amazon EKS and kubeadm for running micro services and pushed microservices into production with Kubernetes backed infrastructure.● Authentication and authorization of users in Kubernetes cluster with the use of RBAC.● Set up CI/CD pipelines for Microservices and integrated tools such as Maven, Bitbucket, SonarQube, Nexus, Docker, Slack for providing immediate feedback to DEV teams after code check-in.● Wrote Ansible playbooks from scratch in YAML for provisioning resources in AWS.● Implemented Maven builds for creating JARs, WARs and EARs and managed the artifacts generated by maven in the Nexus repository.● Created quality gates in SonarQube dashboard and enforced in the pipelines to fail the builds when conditions not met.● Implemented security best practices in AWS including multi-factor authentication, access key rotation, encryption using KMS and TLS, Firewalls, Security Groups, and NACLs, S3 bucket policies. The reason being the client's data security is of great importance.● Designed & architected self-healing, secured, HA & fault tolerant infrastructure in AWS making use of AWS services like ASG, Elastic Load balancers (NLB and ALB.● Used ASG to scale horizontally and vertically based on ingress traffic and CPU utilization, to save on company resources and cost.● Monitored servers, devices, and applications to identify and rectify potential issues on time. Made use of CloudWatch and data dog for intensive monitoring of instances and resources.● Created and maintained name spaces, config maps, secrets, service, ingress in Kubernetes.● Deploying docker images in Kubernetes cluster using YAML manifest files and exposing the application to internet using service object.
