- In-House Hybrid Search – Transitioned ZEE5’s search from a vendor, Sensara to in-house, which led to a massive decrease in cost incurred by Search from 45 million to 5 million annually
- Ideated and developed in-house hybrid search system incorporating both full-text and LLM-powered search which would provide users with a conversational search experience, along with query suggestions
- Full-text search handles Title Search and Episodic Search which is a specially curated feature for OTT platforms where users can search based on episode, specific day, genre, and star cast enhancing content discovery
- Performed load testing on the service and noticed latency being too high for broad queries. Implemented query caching using Redis to store the query embeddings, thereby avoiding repeated calls to embedding generating API and reducing the latency
- Service has shown that it is capable of handling 300 TPS on average and 600 TPS during peak hours with P99 latency being approximately 150ms
- Created a data pipeline with Google Cloud Functions, that will consume any new data published, perform certain transformations, and update SOLR in line with business rules and data security standards
- Transition to in-house hybrid search system has achieved more reliable search results than the external vendor resulting which the Search CTR increasing from 79% to 91%
- Generative-AI Search – Developed LLM-based search to handle broader queries by providing a set of similar rails that would match the user's query
- Leveraged SOLR for vector database, where user query is converted to an embedding to retrieve top ’N’ similar rails
- Built a data pipeline with Google Cloud Functions, that gets triggered when the ML team updates rail and the content mapping in Google Cloud Storage, thereby updating the same changes in SOLR
- The feature had been rolled out for 100% of the iOS users and noted a significant increase in the Search CTR from 79% to 86%

- Developed APIs to create, update, and delete rules to ensure recommended contents are effectively shown to users and meet the business requirements simultaneously
- This would enable the plug-and-play of different ML models based on certain criteria, or to pin newly released content at the top of the rail for a certain period
- Designed and developed a dashboard that would perform all the operations mentioned above, making it easier for team members and product managers to see how the rail would look and perform when it goes live
- Built a feature for the dashboard, where the team can curate their static rails and get an estimate of Click Through Rate (CTR) when it goes live
- These rails can be switched on or off on a flag basis.
