AI Engineer

Generative AI Engineer building production-grade LLM and Agentic AI systems at scale.

  • Architected LLM-powered meeting intelligence using AssemblyAI + FFmpeg + LLaMA-3 with RAG-based Q&A — eliminating ~80% of manual note-taking
  • Designed agentic AI pipeline for resume screening & interview generation using CrewAI + Gemini LLM — dynamic questions, skill-gap analysis, structured reports
  • Built MCP-based recruiter chatbot (MongoDB) for natural language candidate database querying
  • Established RAGAS evaluation framework as production quality gate — faithfulness, context recall, answer relevancy
  • Applied Azure AI + MLOps (Docker, MLflow, DVC, SageMaker) for reproducible, enterprise-deployable models

Assistant System Engineer

Joined TCS and quickly transitioned into AI/ML. Built hands-on experience in Python-based ML, AWS cloud infrastructure, and MLOps — leading to promotion as Generative AI Engineer.

  • End-to-end ML workflows: data preprocessing → model training → deployment on AWS SageMaker
  • MLflow experiment tracking + Docker containerization in live TCS production environment

Personal Project · 2026 · Azure AI · Neo4j · LangChain
Built a production-grade GraphRAG system that combines Neo4j knowledge graphs with Azure OpenAI — enabling multi-hop reasoning over enterprise data that flat vector RAG cannot achieve. Deployed end-to-end on Azure with monitored, auditable AI responses.
01
Knowledge Graph Ingestion — Parsed enterprise documents into Neo4j entities & relationships using Azure Document Intelligence + spaCy NER — preserving semantic structure lost in flat chunking
02
GraphRAG Retrieval — Hybrid pipeline: Cypher graph traversal for relational context + Azure Cognitive Search for semantic similarity — 3× more contextually accurate than vector-only RAG
03
Multi-hop Reasoning — LangChain graph agent traverses 3–5 hops across entity relationships to answer complex cross-domain questions impossible for standard RAG
04
Azure OpenAI + LangChain — GPT-4o generates grounded responses with full graph citation paths — every answer traceable to source nodes & relationships
05
Production MLOps — Containerized with Docker, monitored via Azure Monitor & MLflow, CI/CD via GitHub Actions — enterprise-grade reliability
