I will build a custom rag chatbot for your documents
Desilva Stalin
About this gig
I build custom AI chatbots using Retrieval-Augmented Generation (RAG), so your bot answers questions directly from your own files, FAQs, or knowledge base accurately, in your tone.
What you get:
- LLM integration (OpenAI, Claude, or open-source models)
- RAG pipeline connected to your documents
- Pre-set conversational flow
- Clean, documented source code (Standard & Premium)
- Optional CRM/database integration, authentication & multi-language support (Premium)
I'm an AI Engineer working full-time on production LLM systems RAG pipelines, multi-agent automation, and NL-to-SQL tools for enterprise clients. Same engineering standards apply here, no shortcuts.
I take a limited number of orders at a time so each client gets real attention.
Message me your use case before ordering, and I'll confirm scope and turnaround first.

FAQ
Do I need to give you my documents to build the chatbot?
Yes — share your files, FAQs, or knowledge base after ordering. I'll use these to build the RAG pipeline so the bot answers from your actual content, not generic responses.
Which AI models do you use?
I work with OpenAI, Anthropic Claude, and open-source LLMs depending on your budget and needs. We'll confirm the best fit for your use case before I start building.
Will I get the source code?
Yes, on Standard and Premium packages. Basic includes a hosted/delivered bot without code handover. Let me know if you'd like source code added as an extra on Basic.
Can this connect to my existing website or CRM?
Yes — CRM/database integration is included in Premium, and available as an add-on extra for Basic and Standard. Tell me your stack and I'll confirm compatibility.
Do you offer support after delivery?
Premium includes 30 days of post-delivery support for bug fixes. For other packages, additional support can be added as an extra — just ask before ordering.
