About this gig

I build custom AI chatbots and GPT assistants that actually help your customers, not generic bots.


Your bot is trained on YOUR data (website, docs, FAQs, product info) using RAG, so it answers accurately, in your tone, 24/7 and in any language. It can handle support, qualify leads, take bookings and guide users, then hand over to a human when needed.


What you get: a working chatbot integrated where your customers are (website widget, WhatsApp, Slack, Microsoft Teams); trained on your content so answers stay on-brand and correct; plus a clean setup with deployment and handover.


Why me: 20+ years building software plus deep LLM experience (ChatGPT, Gemini, Claude). I have built full platforms with AI text generation, OCR/PDF pipelines and API integrations (see my portfolio). One contact for build, integration and deployment.


Perfect for SMBs, shops and agencies that want to cut response times and never miss a customer.


Not sure what your bot should do? Message me with your use case and I will map it out and recommend the right package.
