FAQ
Which LLMs and models can you integrate?
I support OpenAI (GPT-4/4o), Anthropic (Claude), Hugging Face models, and Google Gemini via ADK. I’ll recommend the best option based on your project’s needs (accuracy, latency, and cost)
Can you build multi-agent workflows?
Yes. I specialize in LangGraph-based orchestration, allowing multiple agents (planner, tool executor, summarizer, evaluator) to collaborate reliably.
Do you support RAG (Retrieval-Augmented Generation)?
Absolutely. I can set up a RAG pipeline using vector databases like Pinecone, Weaviate, Chroma, or FAISS to let agents answer from your own documents and data.
Will the system be production-ready?
Yes. I include error handling, monitoring, logging, and LangSmith tracing so the agents can run reliably at scale. I also provide Docker/CI/CD setup if needed.
