      Setup and maintain cloud infrastructure (Day1 and 2) in AWS platform. Assist to maintain cloud infrastructure (Day 2) in Azure platform. Built Powershell / Shell scripts to automate tasks in Windows / Linux OS. Built VBA scripts to automate sorting of information (pivotable, vlookup, filtering etc.) in Excel. Setup applications in the virtual machines. Built customized AWS SSM documents in yaml. Things done: • Built Powershell Script to perform a series of steps during maintenance which reduce maintenance process by around 1 hour. • Built Powershell script to run Powershell / Shell script in multiple Azure Windows/Linux VMs (in parallel) from local machine and output to local machine without using Azure Storage. This saves time on opening multiple tabs in web browser to run command on multiple VMs one by one. • Built multiple AWS SSM documents using YAML (mainly) and JSON format for scripts that are run frequently in AWS. Scripts can be run from the console with a few clicks, saving time on unnecessary activity. • Setup routine scripts/tasks on AWS maintenance windows: Routine activity can be scheduled to run in VMs. Eliminate the need for human to run routine scripts in VMs. Eliminate time spent on setting up cronjob and task schedulers on VMs individually. Technology Experience: AWS: EC2, S3, NACL, Security Groups, IAM, Route Table, VPC endpoint, API Gateway, Lambda, Cloudwatch, Load Balancers, Maintenance Windows, SNS etc. Azure: VM. Applications: Palo Alto, Imperva Database Monitoring, Splunk UF & HF setup, WSUS, Windows Active Directory, GPOs etc. Scripting Languages: Powershell, Bash & VBA. Infrastructure as a Code: AWS Cloudformation (yaml). Show less
