About

A Data Scientist with over 3 years of experience specializing in the application of Generative AI and Large Language Models (LLMs) to drive tangible business results. My time at industry leaders like TransUnion and Bajaj Finance has centered on building end-to-end AI solutions, collaborating closely with business and technology teams to understand their challenges and integrate solutions with minimal disruption. My core focus is on practical, high-impact applications. I recently spearheaded the development of a consumer-facing GenAI chatbot that automates customer dispute resolution. By leveraging Retrieval-Augmented Generation (RAG) and finetuning models like Llama 3 and Gemini, this solution reduced customer complaints by a significant volume while simultaneously educating customers in real-time. Beyond large-scale projects, I'm passionate about the entire AI lifecycle. I build scalable and cost-effective systems from engineering ML models for intelligent email routing to building robust data pipelines with a diverse tech stack including Python, PySpark, SQL and PowerBI. To stay at the forefront of this rapidly evolving field, I dedicate time to reading the latest research and applying cutting-edge techniques to personal projects. I am genuinely excited by what's unfolding in the GenAI space and am actively seeking opportunities to apply my expertise to the next wave of complex challenges. I'm always eager to connect with others who are pushing the boundaries of what's possible with data.
