About this gig
Want an AI chatbot that actually knows your business? I'll build one trained on your own content, powered by GPT or Claude.
Senior engineer with 23+ years of experience and deep AI integration work. I build production chatbots that answer from YOUR data (RAG), not generic replies, embedded right on your website.
What I build:
- A chat widget powered by GPT or Anthropic Claude
- Trained on your pages, docs, PDFs, or knowledge base (RAG)
- Custom styling to match your brand
- Optional function calling: bookings, lookups, actions
- Fully deployed and ready to use
Tech: Next.js, TypeScript, OpenAI / Claude, Vercel AI SDK, vector search.
You bring your own OpenAI or Anthropic API key, so you fully control usage costs. Message me with your use case and I'll recommend the right package.

FAQ
Whose API key does the chatbot use?
You provide your own OpenAI or Anthropic API key, so you fully own and control usage costs. I handle all the setup.
What can the chatbot use as its knowledge?
Website pages, documents, PDFs, FAQs, or a database/API. Share clean sources; data cleanup can be added as an extra.
Can it do more than answer questions?
Yes. On Premium I add function calling, so it can take actions like bookings, lookups, or form submissions.
Will it match my website's design?
Yes. Standard and Premium include a custom-styled widget that matches your brand.
Do you provide ongoing support?
Setup, deployment, and handoff are included. Ongoing maintenance can be arranged separately.
