Project History
AI Sourcing Copilot | RFP-to-shortlist Automation
I designed the agentic workflow, RAG, and retrieval strategy, enterprise integrations, security and access-control approach, and the evaluation framework. The solution also generates candidate analysis, a PowerPoint summary, and a contextual email draft, while keeping human approval in the loop. I implemented monitoring and observability and introduced RAGAS-based evaluation based on faithfulness, answer relevancy metrics, and context precision. I also defined the path from POC to an industrialized enterprise product, including golden datasets, regression testing, quality thresholds, governance, scalability, and cost controls.
Enterprise GraphRAG Knowledge Assistant
I worked on the retrieval and generation architecture, including semantic search, graph-based context enrichment, and LLM orchestration.
The solution was designed to support both simple and complex questions by combining structured relationships with unstructured document content, while keeping retrieval grounded in enterprise sources. I also evaluated retrieval quality, relevance, and answer grounding, and considered production requirements such as access control, observability, scalability, and the trade-off between a conventional RAG architecture and GraphRAG.
Agentic AI Strategy & Operating Model for Transportation Operations
Defined a phased AI roadmap and target operating model covering business ownership, AI product teams, data and system integration, agent/tool access, human approval points, evaluation KPIs, governance, and LLMOps. The workshops aligned Operations, IT, Data, Customer Service, Security, and Risk teams around a controlled path from prioritized use cases to pilots and production scale.
