I will build a dify rag chatbot and integrate your business apis
Yunfeng W
About this gig
Turn your company documents into a practical AI assistant.
I am a Java backend engineer with 10 years of experience and a background as a technical lead and team leader. I build RAG knowledge bases, AI agents, and workflows, with hands-on work integrating Dify, RAGFlow, and GPUStack.
For this Gig, I will use Dify to build an assistant that answers from your documents and shows source references where supported. Choose a package for knowledge-base setup, deployment and website embedding, or a business API integration such as an order-status lookup.
You will receive the configured application, a short handover guide, and validation against an agreed set of sample questions. I focus on clear scope, maintainable implementation, and documented delivery.
Please message me on Fiverr before ordering so we can confirm your documents, hosting, and integration needs. We will communicate through written Fiverr messages.
You provide the server and model access; hosting and model usage are billed separately by their providers. Scanned-document OCR, custom frontend design, and ongoing maintenance require a separate quote.

I build Java backends and AI applications that connect your documents, data, and business systems. With 10 years in Java development and experience as a technical lead and team leader, I deliver APIs, microservices, RAG knowledge bases, AI agents, and automated workflows.

I collaborate through written messages and clear project documentation.
FAQ
Do I need my own server and model account?
Yes. Basic requires a working Dify environment. Standard and Premium include deployment to one suitable Linux server that you provide. You pay hosting and model usage costs directly to the providers and configure your own model keys.
How will we communicate and handle revisions?
We use written Fiverr messages and documents; voice/video meetings are not included. Revisions adjust agreed prompts, retrieval settings, or configuration. New features or changed scope need a separate quote. Defects in the agreed deliverable are corrected without using a revision.
What are the document and deployment limits?
Basic: 10 text files, 100 pages, and 10 test questions in your Dify. Standard/Premium: 30 files, 300 pages, 20 questions, one Linux server, and one existing-page widget. All packages cover one chatbot, one knowledge base, one document language, and one model provider. OCR is extra.
What does Premium API integration include?
Premium adds one Dify workflow of up to five steps and one working, documented API with up to two endpoints, including basic authentication and error handling. New Java services, complex permissions, RAGFlow/GPUStack integration, and ongoing maintenance need a custom quote.
