About this gig

Have an idea for an AI product but need help turning it into a working application?


I can build a focused AI website, web application or mobile MVP around your business needs. Whether you need a chatbot, document search system, intelligent recommendation feature or custom AI integration, I will help plan and develop a practical solution.


I can help with:

  • Custom AI websites and web applications
  • Mobile application MVPs
  • AI chatbots and RAG systems
  • Document search and information extraction
  • AI generated content and replies
  • REST APIs and database integration


My projects include QFind, a contract analysis RAG chatbot with cited evidence, and EcoPlate, a full stack sustainability platform using AI receipt scanning and machine learning recommendations. I have also developed an Android mobile application using Kotlin.


You will receive clean code, clear communication, testing and proper documentation.

Hosting, API usage, app store fees and paid third party services are not included.


Please message me before ordering so we can confirm your features, platform and project scope.

Hi, I’m Yong Hui. I help businesses build AI automations, RAG chatbots, document search tools, LLM integrations, and custom AI features. My recent work includes an AI lead enquiry system that extracts details, qualifies leads, updates HubSpot, sends tailored replies, and alerts teams on Telegram. I also built QFind, a contract chatbot that answers questions with cited evidence. I focus on understanding your needs, communicating clearly, and delivering reliable, well documented work. Message me to discuss your idea. View my work: github.com/YongHui-X
