Jun 2017 – Sep 2018 · 1 yr 3 mos · Noida, Uttar Pradesh, India

• Working on search and personalization. Key responsibilities are:
• 1. Create an end to end pipeline for data gathering and processing using spark real time and batch jobs.
• 2. Define user profile based on user's history and improve user's search experience.
• 3. Implement "implicit feedback model for recommendation" based on user's history. Most of the recommendations are generated based on the explicit user rating data, for our use case we don't have the explicit rating data and hence have to resort to implicit user preferences data. Extracting the appropriate data that can be used to train recommendation model was a major challenge, and after many iterations were able to achieve excellent model performance.
• 4. Architecting and implementing solr search api's and solr indexing for application search.
