ECR project's goal is to generate three different types of files (account, activity and position) per financial firm, whose employees have accounts with Edward Jones, every night and send them to the Platform, the financial firm is associated with. The formatting of the files is defined by the Platform the firms use. Involved in this project from design phase to deployment phase. The Redesign of ECR process consists of web front end, API services layer, Kafka Producer and Kafka Consumer applications. Involved in design of these applications from the beginning and worked mostly on development of Producer and Consumer applications. Worked on setting up MongoDB instance with DB Team which includes design of logical and physical models and development of Json Schemas for the collections and implementing them in all environments.
