• 1)Involved in implemention of AmEx BigData secure platform for efficient data access , capable of handling petabytes of data used by 1000s of end users.
• 2)Implemented a producer-consumer multithreaded application from scratch to process the data ingestion requests.
• 3)Developed REST APIs for generating the schema of a table, retrying of failed data ingestion requests and onboarding data ingestion requests.
• 4)Optimised the performance of our cleanup mechanism code from 3 hrs to 20 minutes by converting the insertion and updation code to batch processing.
• 4) Implemented the dequeue mechanism in our existing system which offloads the futile loads from the waiting queue making our application more resilient which in turn also helped the end user to not worry about those loads they ingested.
