Hire Atharva B. - LLM Engineer

Sole backend engineer for Shopper Go mobile app and Agency Suite modules — owning API design, AI feature integration, and production deployments end to end. Built TurtleCRM: a LangGraph supervisor orchestrating 9 domain-specific sub-agents that extract structured data from meeting transcripts into a 174-field fintech CRM schema, with per-field confidence scoring and human-in-the-loop validation before any data is committed. Architected an event-driven async pipeline on RabbitMQ with transactional outbox, dead-letter queues, and circuit breakers — supporting transcript ingestion, AI extraction, persistence, and summary generation as independent consumers. Built an AI-driven contract analyser: automated clause extraction, semantic differencing between contract versions, and risk scoring — reducing legal review time for the sales team. Migrated services to .NET 8, containerised with Docker, and automated deployments via Jenkins CI/CD; hardened security with Keycloak RBAC, JWT, and SSL/TLS.

Engineered and deployed production-ready RAG (Retrieval-Augmented Generation) pipelines using LangChain and LlamaIndex, improving data retrieval accuracy for internal knowledge bases. Developed custom LLM agents to automate complex data extraction from unstructured PDF documents, leveraging OpenAI’s GPT-4 and open-source models like Llama 2. Optimized vector database performance using Qdrant and FAISS, implementing hybrid search techniques to enhance semantic relevance in chatbot responses. Designed and refined complex prompt templates and evaluation frameworks to reduce hallucinations and ensure consistent AI output across multiple use cases.
