• Part of development team for planning applications in Flipkart.
• Demand Planning application helps Flipkart to plan it’s sales better. This tool takes in future events’ data which is basically burn in rupees on particular products on various days in the future and tries to predict the impact of the burn on the sale. This tool is used by Demand Planner to optimize the sale to burn ratio.
• As part of my job, I have worked on a library that is being used across planning team to power planning applications. This is done using a multi-tier datastore approach. We are using a mysql + elasticsearch setup. MySql is the source of truth and ElasticSearch is used for quick performance of aggregated queries.
• Demand Planner fills in Intervention details in UI which is captured in MySQL as first class entity and it’s meta is then flushed to ES(ElasticSearch). This approach helped in scaling the system.
• Flushing of Intervention Meta - Intervention Meta is captured as first class column in MySQL. This is then flushed to ElasticSearch Index using scheduled Azkaban Job. The azkaban job marks the Intervention in MySQL as Flushed once after it’s Meta is flushed successfully.
• I have got exposure to UI creation in play framework using it’s twirl engine and bootstrap javascript. The API endpoints (MVC) are in scala as in play framework.
