About

Interested in Collaborations & Research | Gen AI | LLM | Deep Learning | Machine Learning I am passionate about solving real-world problems through creative ideas and innovative solutions. With a growth mindset, I view failures as opportunities to learn and improve. I enjoy mentoring colleagues, believing in the power of shared knowledge to foster growth. Feel free to DM me—I'm always happy to help and collaborate! As a Senior Principal GenAI Engineer with 12+ years of experience, I have built and deployed AI and machine learning solutions across healthcare, fintech, e-commerce, and enterprise domains. My career spans leading organizations including GSK, PayPal, HP Inc., Johnson & Johnson, Wipro, and Infosys, where I have transformed complex business challenges into scalable AI products. My expertise lies in Generative AI, Large Language Models (LLMs), Retrieval-Augmented Generation (RAG), agentic workflows, NLP, and applied machine learning. I specialize in designing end-to-end AI systems—from data and model architecture to deployment and production optimization—focusing on measurable business impact and customer experience. At GSK, I am building enterprise-grade GenAI solutions, including multi-agent orchestration systems using LangGraph and RAG-based applications. Previously at PayPal, I contributed to conversational AI initiatives involving intent detection, entity extraction, smart replies, and content moderation using transformer models and fine-tuned LLMs. Throughout my career, I have led initiatives that improved customer experience, reduced manual effort, and enabled intelligent automation at scale. Passionate about innovation and continuous learning, I have worked extensively with GPT models, BERT, Sentence Transformers, Hugging Face, PyTorch, TensorFlow, and vector databases, delivering production-ready AI systems while driving technical excellence and thought leadership.
