FAQ
What frameworks do you use to build AI agents?
I use LangGraph for stateful multi-step agent workflows, CrewAI for collaborative multi-agent systems, and the OpenAI Agents API for function-calling and tool-use agents. The choice depends on your specific use case.
Can the AI agents integrate with my existing systems?
Yes! I build agents with custom tool integrations for REST APIs, databases, web scraping, code execution, and third-party services. Agents can read/write data to your existing infrastructure.
What AI models do you support?
I work with OpenAI GPT-4, Anthropic Claude, Google Gemini, and open-source models via LangChain. I can set up model routing and fallback strategies as needed.
How do you handle agent memory and context?
I implement short-term memory (conversation buffers), long-term memory (vector stores like Pinecone or ChromaDB), and entity memory for tracking important facts across sessions.
Do you provide deployment and documentation?
Yes, every project includes full deployment to your preferred cloud (AWS, GCP, Azure, or Railway), documentation, and a handover session to ensure you can manage and extend the system.
