About this gig

Most AI chatbots either hallucinate or can't reach your real business data. I build AI chatbots that do neither.

Senior full-stack engineer, 4+ years shipping production AI systems, including a live call-automation platform running OpenAI with real-time transcription and vector search across thousands of customer conversations.

WHAT YOU GET

  • Custom AI chatbot trained on YOUR content: docs, website, PDFs, database
  • RAG and vector search so every answer is grounded, not invented
  • OpenAI, Claude, Gemini or self-hosted Llama
  • Customer support, lead capture, booking or internal AI agent
  • Website widget, WhatsApp, Slack, SMS or custom API
  • CRM and database integration
  • Clean source code and documentation, you own it

TECH: Python, FastAPI, Node.js, LangChain, Pinecone, pgvector, React, Next.js, PostgreSQL, n8n

WHY ME

  • 1,100+ freelance hours for US and EU clients
  • Real production chatbots, not no-code wrappers
  • Plain-English answers on cost and trade-offs before you spend

Tell me what you want your AI chatbot to do. I'll reply with exact scope, price and timeline, free, before you order.
