· Built high-performing, resilient, and efficient infrastructure for customer applications, and performed reviews for architecture and infra builds. · Developed CI / CD to standardize the infrastructure and automate the DevOps processes, allowing customers to rapidly build, test, and release code while minimizing errors. · Managed provisioning of AWS infrastructures using CloudFormation and Terraform.· Designed for high availability and business continuity using self-healing-based architectures, fail-over routing policies, multi-AZ deployment of EC2 instances, ELB health checks, Auto Scaling, and other models based on customer’s functional and non-functional requirements.· Developed event processing architecture patterns with event trigger, logging, analysis, visualization, notification and responding.· Developed and implemented DDoS-resilient architectures.· Eliminated single point of failure in production architecture designs by deploying service instances (e.g., EC2 or RDS) across two or more isolated AZs based on our customer’s actual resiliency and availability requirements. · Leveraged Auto scaling groups to right-size EC2 pools to match the level of demand and helped to manage costs by eliminating excess capacity to maintain optimal level of resources.· Democratized advanced technologies in our architecture patterns including leveraging ECS, EKS, Lambda functions, parameter store, DynamoDB etc.· Planned, architected, and built large-scale data processing systems; orchestrated the successful implementation of data movement, transformation, analytics, and reporting solutions with the AWS cloud.

· Designed secure, cost-optimized, highly available, and fault-tolerant infrastructure in AWS.· Architected and configured Dev / Stage / QA environments in AWS (VPC, subnets, security groups, EC2 instances, load balancer, RDS, Redis, route53, etc.). · Implemented security best practices in AWS including multi-factor authentication, access key rotation, role-based permissions, enforced strong password policy, configured security groups and NACLs, S3 bucket policies and ACLs, etc.· Optimized cost through reserved instances, selection and changing of EC2 instance types based on resource need, S3 storage classes and S3 lifecycle policies, leveraging Autoscaling, etc.· Leveraged EC2 CreateSnapshot API call to create snapshots of EBS Volumes on scheduled intervals.· Configured CloudWatch alarm rules for operational and performance metrics for AWS resources and applications.· Configured S3 events to set up automated communication between S3 and other AWS services.· Monitored end-to-end view of runtime systems CPU, bandwidth, disk space, and log files using NewRelic.· Deployed and configured infrastructure using Terraform and Ansible.

• Implement security best practices in configuration and installation in AWS, including multi factor authentication, access key rotation, role-based permissions, load balancers, Redis, route 53, etc.• Optimize cost by reserving instances, selections and changing of EC2 instance types based on resource need, S3 storage classes and S3 life cycle policies, leveraging Auto Scaling, etc.• Leverage EC2, created snapshot API call to create snapshots of EBS Volumes.• Configure Cloud Watch alarm rules for operational and performance metrics for AWS resources and applications.• Setup and configure log files for detail monitoring and alert notification when changes are made.• Leading on designs/development aspects of migration journey - assess, mobilize, and migrate phases including leveraging CART, ADS, Migration Evaluator, DMS, Cloud Endure etc.• Automatically remediated Trusted Advisor findings using Amazon CloudWatch events and AWS Lambda• Developed SOP and work instructions for enabling, provisioning, and operating in AWS following design principles that are based on the AWS well architect best practices.• Designed for high availability and business continuity using self-healing-based architectures, fail-over routing policies, multi-AZ deployment of EC2 instances, ELB health checks, Auto Scaling, and other disaster recovery models.• Implemented AWS Systems Manager management service capabilities to automatically collect software inventory, apply OS patches, and automate administration tasks and complex workflows across our environments. • Configure S3 events to set up automated communication between S3 and other AWS services.• Deployed and configured infrastructures using Ansible.• Manage provisioning of AWS infrastructures using CloudFormation.

· Migrated high availability webservers and databases to AWS EC2 and RDS with minimum or no downtime.· Life cycle configuration for data to live and cycle within buckets in accordance with how often it can be accessed thereby minimizing cost. · VPC build with Private and Public Subnet couple with VPNs setup back to on premise datacenter and corporate offices.· VPC peering with other accounts allowing access and routing to service and users of separate account to communicate. · Prepare Standard Operating Procedures (SOPs), work instructions, and related supporting documents based on Quality Systems Unit guidelines.
