AI Research Engineer @ AlphaSense | RAG, LLMs & Agentic Workflows | Kaggle Competiton Master | Ex-Microsoft | IIT Guwahati

About

I am an AI Research Engineer passionate about bridging the gap between theoretical deep learning and scalable, production-grade systems. Currently, I work on the RAG team at AlphaSense, building hybrid learning-to-rank systems, multimodal retrieval pipelines, and agentic workflows that power next-gen search intelligence. Previously, I was a Software Engineer at Microsoft (Azure Container Instances), where I optimized cloud security and orchestration at a massive scale. My expertise lies in Mechanistic Interpretability, Bias Detection in Generative Models, and designing complex retrieval architectures using LangGraph and VESPA. Beyond engineering, I am a Kaggle Competitions Master (Top 0.15% globally) and an active researcher with work published at COLING and IEEE. I thrive on solving hard problems—whether it’s optimizing NDCG by double digits or detecting subtle biases in text-to-image models.
