Principal AI Scientist @ Verizon | Building Gen AI, LLM solutions
As a Data Scientist with over a decade of experience, I specialize in designing, deploying, and scaling intelligent systems across industries—from e-commerce and finance to telecom and healthcare. I’ve led AI product teams, driven IP creation, and built robust MLOps pipelines that power impactful applications in Generative AI, LLMs, and NLP. With hands-on expertise in model architecture, deployment (SageMaker, Azure, GCP), and real-world problem-solving Gen AI use cases, I bring a product-oriented, research-driven mindset to every project. Currently open to exciting opportunities where I can lead innovation in AI and make data work smarter. Let’s connect if you’re building the future with AI in particular, Gen AI & LLM. Currently, I am part of the Cognitive AI Science team at Verizon building and deploying state-of-the-art models for information retrieval, conversational AI, and question answering using LLMs, Machine Learning(ML), and Deep Learning. I am always : * Curious about building AI models - Machine Learning/Deep Learning models (from development to deployment) - Information Retrieval Systems - Conversational AI systems - Question and Answering models My research interests have recently shifted towards Multimodal models, RAG, Reasoning models, and Reinforcement Learning using LLMs. Currently working on multi-turn, conversational, reinforcement learning-based post-training on LLM models, reward modeling, RLHF, and Agentic AI systems. * Also, built large-scale systems and data pipelines using - distributed processing, parallel computing - handling inference challenges at scale **Lately using these skills for our models: Programming languages - Python Distributed framework - Ray ML frameworks - Pytorch Deployment & MLOps - Git and Docker, AWS Sagemaker, Docker, Kubernetes, ML
