Prashant Singh

Lead AI / Data Engineer — GenAI, ML & Data Platforms

I build and run data and AI platforms for regulated finance. Twelve years across banking and asset management — currently owning curated datasets and regulatory disclosure pipelines at Nomura Asset Management, and prototyping GenAI capabilities that hold up to audit: LLM integration and evaluation, RAG, and agentic workflows with LangGraph and MCP. Deep in Python, Snowflake, Airflow, Spark, and AWS; hands-on ML across credit scoring and fraud detection.

03AI Projects

RBI Circular Summarizer — Bankopedia

Agentic AI · Live

An agentic AI application that ingests Reserve Bank of India circulars and publishes Claude-generated summaries on bankopedia.co.in. Orchestrated as a LangGraph agent workflow over a RAG pipeline — document chunking, BGE embeddings stored in ChromaDB — with prompt engineering, output validation, and guardrails keeping every summary faithful to the source regulatory text.

Project Synapse

Knowledge Graph

A knowledge graph of a codebase in Neo4j, modeling code structure and relationships, that translates a production error directly into the pinpointed source of the issue and a suggested fix. Combines graph traversal with semantic retrieval over BGE embeddings in ChromaDB, linking error signatures to the relevant code and fix context.
