FAQ
Can you help me choose between proprietary and open-source models?
Yes! I will analyze your project requirements, budget, and scalability needs to recommend the best option—whether it's OpenAI, Gemini, Claude for cutting-edge performance, or open-source models like Qwen, Llama 3, or Mistral for cost efficiency and full control.
What tools and frameworks do you use?
I use modern AI tech stacks including LangChain, LlamaIndex, n8n, Zapier, vector databases like Pinecone, Weaviate, and Chroma, plus cloud deployment on AWS, GCP, or Azure.
Do you provide support after delivery?
Yes, I offer revisions as per package selection and provide documentation. Post-delivery support can be discussed based on your needs.
