FAQ
What do I need to provide before we start?
Please share your requirements, use case (e.g., chatbot, RAG, AI agent), preferred LLM (OpenAI, Ollama, etc.), any data or API access (if needed), and design expectations. If unsure, message me—I'll help define what’s needed.
Can you deploy the app for me (AWS, Docker, Vercel, etc.)?
Yes, deployment is included in Standard and Premium packages. I can deploy to AWS EC2, Docker, Vercel, or Supabase—based on what fits your app best.
What LLMs and tools do you support?
I work with OpenAI (GPT‑3.5, GPT‑4), Ollama, Hugging Face models, LangChain, LangGraph, FastAPI, Pinecone, Chroma, and more. Custom tool integrations (email, Stripe, Twilio) are also supported.
Will I get the source code?
Absolutely. You’ll receive complete, well-documented source code, API specs, and setup instructions. I can also walk you through it if needed.
Can you create both the backend and frontend (UI)?
Yes! I use FastAPI or Flask for the backend and Next.js (React) for frontend. Standard and Premium packages include full-stack delivery.
Can I get a chatbot that pulls answers from my own documents?
Yes! I can implement a Retrieval-Augmented Generation (RAG) system that uses your PDFs, CSVs, or website data to answer user queries intelligently.
Do you offer ongoing support or maintenance?
Yes, Premium packages include 14-day support. For longer-term support or feature extensions, I offer custom add-ons or monthly retainers.
