• Integrate LLMs (OpenAI, Anthropic, Google Vertex AI, open-source models) via REST APIs and SDKs into scalable backend services.
• Develop and maintain RESTful APIs (FastAPI) to deliver AI-powered functionalities to front-end applications and external consumers.
• Architect and manage vector database solutions (Milvus) for semantic search and RAG.
• Create context engineering strategies, including prompt templates, dynamic context window management, token optimization, and context compression techniques.
• Implement short-term memory (conversational buffers, sliding windows, summary memory) and long-term memory (persistent vector stores, knowledge graphs, user profile stores) using MongoDB and vector databases.
