About this gig

Are you looking to add a powerful AI assistant to your website or application?

I build custom AI chatbots powered by OpenAI and Anthropic Claude. I have built multiple production AI products including an AI companion platform, a workflow automation platform with 57 templates, and an AI chatbot builder SaaS all live right now.

What I can build for you:

  • Customer support chatbots that answer questions 24/7
  • AI assistants trained on your business knowledge base
  • Lead generation bots that qualify prospects automatically
  • Internal tools and employee-facing assistants
  • AI integrations added to your existing website or app

Technical capabilities:

  • OpenAI GPT and Anthropic Claude API integration
  • Custom prompt engineering for your use case
  • Database integration for conversation history
  • Clean embeddable widget for any website
  • Full source code on Standard and Premium plans

Why work with me:

  • Real AI products built and deployed, not just API wrappers
  • Clean, documented, maintainable code
  • I understand both technical and business sides of AI
