Experience

1. Senior Applied Scientist

   Microsoft

   May 2022 — Present · Bengaluru, IN

   Building Turn-Based Agentic Search, iterating on SLMs for planning and tool selection, and LLMs for grounded answer generation with multi-step reasoning.2. Developed offline pipelines for generating LLM-based titles, captions, and web answers for Bing\'s top search queries. Engineered a vector index using HNSW to cache this content and serve it on the Search Results Page via nearest neighbor searches. Additionally, experimented with various embedding queries to optimize performance. Built online LLM captions generation without impacting overall page rendering time. Built a high scale system that triggers LLM preemptively before ranking and save inferences to a distributed cache. As ranking is finished, generated captions would be picked up from cache. Built comprehensive observability to record metrics for each step to optimize system end-to-end latency. Enhanced Bing Search Results by using LLMs by chaining prompts for intent generation, alternative queries, and re-ranking. This utilized Chain of Thought Prompting, where the LLM was guided step-by-step to provide results with reasoning. Additionally, developed a streaming engine that sends LLM output tokens to the UI, masking the reasoning.
