At PwC India, I developed RIWA, a GenAI-powered chatbot for billing and general queries, and extended it with a knowledge base. I also used OCR, Python ML workflows, and RAG pipelines to streamline supply chain operations, boosting efficiency by 60% and reducing costs through automation.

Earlier, as a Backend Intern at WeSolveForYou, I worked on data analysis across advertising and commerce platforms, website improvements, and features for the CleverCanine platform. At Advancedware Technologies, I engineered backend APIs for CRM software and implemented payment systems using Razorpay and PayPal.
