Experience

1. Generative Ai Engineer

   UnitedHealthcare

   Jun 2024 — Present · San Francisco, CA, US

   At United Healthcare, I lead the development and deployment of scalable AI solutions focused on NLP, GenAI, and real-time inference. I build complete ML pipelines—covering everything from data ingestion and preprocessing to model training and production deployment—using tools like Python, Spark, Airflow, and MLflow.A core part of my role involves designing and implementing NLP models for sentiment analysis, classification, and named entity recognition using spaCy, BERT, and Hugging Face Transformers. I’ve also integrated advanced LLMs like GPT-4 and BERT into enterprise chatbots, summarization tools, and retrieval-based Q&A systems using LangChain, OpenAI API, FAISS, and Pinecone.I specialize in developing Generative AI applications, including retrieval-augmented generation (RAG) systems for intelligent document processing and knowledge search. I deploy scalable AI microservices using Docker, Kubernetes, and FastAPI, ensuring low-latency responses and seamless integration with existing systems.Model monitoring and automation are key to my work. I’ve built workflows for drift detection, version control, and retraining using MLflow, GitHub Actions, and Evidently AI. I also focus on explainable AI, using SHAP and LIME to ensure model transparency and fairness in high-stakes use cases.On the cloud side, I manage model training and deployment across AWS SageMaker, GCP Vertex AI, and Azure ML. I work closely with data engineers to develop robust, scalable data pipelines using Kafka, Snowflake, Delta Lake, and BigQuery.I also contribute to innovation and mentoring—evaluating open-source LLMs like LLaMA, Mistral, and Falcon, experimenting with RLHF for improving conversational agents, and guiding junior team members on best practices in GenAI and MLOps.
