• Worked in risk and forecast solution team as data engineer. As part of this team, I worked on designing and developing batch processing data pipeline for risk and forecast solution data using Redshift, EMR, Glue and StepFunction. Pipeline was designed to read data from S3, process it and then store in Redshift. Due to this pipeline processing time was reduced from few hours to 30 mins.
• Designed and developed data pipeline for processing rule breaches and commentary data using EMR, Glue, StepFunction and S3.
• Worked on development of multiple services and API to generate various parameters to calculate and analyse risk factors.
• Developed automated rule engine service to perform automated critical validations and control check on upstream data.
• Developed machine learning model to replace rule engine service: Classification model to identify rule breaches.
