About Umesh Linga
Data Scientist with Gen AI expertise and 5+ years of experience delivering intelligent analytics solutions across banking and enterprise IT environments. At US Bank, I design scalable data pipelines using PySpark and SQL for high-volume financial datasets, and build RAG pipelines with vector databases (FAISS, Pinecone) for context-aware LLM-powered insights. I\'ve integrated Azure OpenAI and GPT-4 into production fraud detection and risk analytics systems, deployed on AWS/Azure with Kubernetes and CI/CD pipelines. Previously at DXC Technology, I built Python data applications for ETL, feature engineering, and anomaly detection, implemented ML pipelines with FastAPI/Flask, and developed real-time event-driven architectures using Kafka.
