   Identifying & fixing issues in existing orchestration system. I worked on one of the orchestrations where I had to perform POC on serializing the execution queue which involved AWS Step function, Lambda, DynamoDB, Event Bridge, S3, Python.• Identifying customer needs and automating daily activities by providing AWS-specific solutions.• Worked on optimizing activity where the customer needs list of tables that are duplicated across clusters and maintain singularity for tables. Performed a POC to address this issue and saved 150TB of space with table volume of 400 Tables which saved 2Hrs per week on client end.• Worked on identifying list of tables with column defined as Max Varchar so that customers can target these tables and optimize them by changing their corresponding datatypes and compressions.• Customer uses Step functions for orchestrations, and they didn’t have a way to track them all at one place. Hence a specific team (cloudops) was keeping track on these critical step functions and keep pipelines up to date. Hence, I’ve identified this issue and provided a solution which generates Step function audit trails and sends the trail information through an email which saved customers 5Hrs a week.• Customers use EC2 machines to store log files and other code files and run them through this place. There was a time when there was no space on EC2 to store log files and hence the scripts were going into error. I took up this activity of uploading logs to Cloudwatch instead of placing them in EC2. Which saves them an ample amount of space to perform their daily activities.
