Work Experience
Senior AI Engineer
M42
- Built an AI-powered analytics platform that uses large language models and retrieval-augmented generation (RAG) to turn natural language queries into dynamic SQL and automated visualizations, enabling the analysis of clinical and environmental data.
- Developed a physician-focused chatbot that facilitates access to patient EHR data by using a multi-agent framework and RAG to process information in FHIR format, improving efficiency and supporting better decision-making for healthcare providers.
- Engineered an AI-assisted genetic variant pathogenicity classifier that searches and interprets scientific literature and bioinformatics data to assess pathogenicity in line with guidelines, reducing variant analysis time by four hours per patient.
Lead AI Engineer
Airtel India
- Drove a team of six to develop a contact center call monitoring system powered by automatic speech recognition (ASR) technology.
- Architected a lead-mining system for contact centers that analyzes 200,000 daily calls for potential leads, increasing lead conversion by 10%.
- Built an intent classifier and an emerging-intent discovery model for a chatbot, increasing intent coverage by 16%.
Data and Applied Scientist II
Microsoft
- Developed an aspect-based sentiment analysis system to extract insights and evaluate user sentiments from Windows-related social media data.
- Engineered feedback-mining algorithms to analyze Feedback Hub data, identify high-impact bugs, and quantify the affected user base.
- Implemented data pipelines to analyze telemetry and app usage data, revealing user behavior and informing feature prioritization.
Tech Lead
InfoEdge
- Spearheaded AI initiatives at Shiksha.com, establishing NLP and integration teams and building scalable compute infrastructure.
- Directed the development of a virtual service agent, introducing new offerings for universities through Shiksha.com.
