At Tata Consultancy Services, I built and deployed GenAI systems for CVS Healthcare USA, including Astra, an agentic platform for SDLC automation. Astra generates user stories and test cases and supports automated QA, delivering 85%+ test coverage and reducing manual QA effort by 65%.
I shipped agentic RAG tools for conversational BI, IT ticket resolution, and unit test generation, driving a 40% productivity gain and a 50% drop in manual effort. I also fine-tuned a LLaMA 3.1 14B model for insurance claims recommendations, improving accuracy by about 35%.
Earlier, as an Advanced Data Analyst Intern at PricewaterhouseCoopers (PwC), I analyzed 800K-row datasets and trained time-series prediction models that achieved 86% accuracy. I also built and deployed three end-to-end ML models as a Machine Learning Engineer Intern at InternShala.
