* LLM Evaluation & Model Comparison: Define prompt testing methodologies, benchmarking metrics, and evaluation frameworks (accuracy, hallucination reduction, response consistency, token efficiency, latency, cost optimization) across multi-LLM environments.

* RAG & Knowledge Grounding: Support Retrieval-Augmented Generation (RAG) architectures, vector database integrations, and enterprise knowledge grounding strategies to ensure hallucination-free, context-aware responses.

* Governance & Responsible AI: Establish enterprise prompt governance standards, safety guardrails, PII redaction patterns, and compliance protocols for production AI deployments.

* Agile Sourcing & Production Integration: Collaborate with Product Owners, Conversational Designers, Data Scientists, and Business SMEs to translate business requirements into prompt libraries, reusable interaction patterns, and API payloads (Python/JSON).

* Continuous Analytics & Optimization: Analyze conversational logs, user feedback, and contact center metrics to iteratively refine prompts, improve intent matching, and boost Customer Satisfaction (CSAT).
