Deployed low-latency inference services via FastAPI-based microservices with monitoring and automated retraining. Built agentic AI systems using LangChain and LangGraph with tool-calling and multi-step reasoning. Implemented LLM workflows with context management, guardrails, and robust access controls to

AI/ML Engineer at Verisk Analytics

August 1, 2024 - July 1, 2025

Optimized Snowflake data models and complex SQL transformations to support scalable AI/ML workloads and Retrieval-Augmented Generation (RAG). Designed and implemented end-to-end RAG architectures with embedding generation, vector similarity search, semantic retrieval, and context injection to enable accurate, context-aware LLM responses. Built high-performance PyTorch inference services integrated with backend systems and distributed pipelines, supporting real-time and batch processing with low latency. Developed NLP and predictive analytics models to enhance claims processing and underwriting workflows, leading to better decision-making. Engineered secure AWS-based infrastructure (VPC, IAM, encryption) and robust data ingestion pipelines for structured and unstructured data (contracts, claims, policy documents). Improved claims processing efficiency by 35% via multi-agent LLM-based summarization, automated retrieval, and decision-support. Fine-tuned transformer models on domain-specif

Data Scientist at eSparkBiz Technologies

June 1, 2021 - July 1, 2023

Implemented robust data ingestion frameworks using Python and Azure Data Factory to consolidate financial statements, macroeconomic indicators, and historical rating data from diverse sources. Designed scalable feature engineering pipelines using Pandas, NumPy, and PySpark for risk modeling and temporal analysis.
