* LLM Strategy & RAG: Define model selection, fine‑tuning strategies, and build Retrieval‑Augmented Generation (RAG) pipelines to ensure contextual accuracy and reduced hallucinations.
* Context Engineering: Establish frameworks for memory retention using embedding stores, Vector Databases, and persistence strategies.
* Integration: Architect prompt management and function‑calling layers to seamlessly integrate AI agents with backend APIs, microservices, and UI/UX layers.
* Governance & Compliance: Implement strict observability and governance frameworks to ensure all GenAI deployments meet enterprise data security and regulatory standards.
