About this gig
Have useful business knowledge trapped in PDFs, webpages, FAQs, or internal documents?
I build custom AI chatbots that help your customers or team find reliable answers from your business content. Whether you need a chatbot for your website or an AI feature inside your SaaS, I handle the frontend, backend, data connection, integrations, testing, and deployment within the agreed scope.
You don't need to understand RAG, embeddings, or vector databases. Tell me what you want your users to do, and I'll recommend and build the right solution.
I test the chatbot with real user questions, including questions your content doesn't answer, so it behaves predictably and its limits are clear. The goal is a useful, maintainable product, not just a basic demo.
Message me before ordering with your idea, data source, website or SaaS, and desired outcome. I'll review your requirements and send the right scope or a custom offer.

Not every project I've shipped was clean. A few were painful. All of them shipped, and the clients were happy. That is what I sell. I help founders use AI to remove manual work and capture more leads. I build custom SaaS platforms, voice agents, and RAG systems that run 24/7. If you have a clear use case, message me and we will map it to AI.

FAQ
What LLMs and AI models do you work with?
I work with GPT-5, GPT-4o, Claude (Anthropic), Llama, and Mistral. The right choice depends on your accuracy needs, budget, and whether you want a hosted API or self-deployed model. For privacy-sensitive use cases, I deploy open-source models on your own infrastructure.
Can the chatbot answer from my company's documents?
Yes, that is what RAG does. I process your PDFs, Notion pages, Google Docs, or website content into a vector database like Pinecone or Supabase. The chatbot answers using only your content, with no hallucinations and no generic outside answers.
Do you connect the chatbot to my CRM or helpdesk?
Yes. I integrate with HubSpot, Salesforce, GoHighLevel, Intercom, Zendesk, Slack, and WhatsApp. The chatbot can read user data, create tickets, log conversations, and trigger automated workflows. If your tool has an API, I can connect it.
What is the difference between a regular chatbot and a RAG chatbot?
A regular chatbot answers from general training data and often invents details. A RAG chatbot retrieves answers from your private knowledge base first, so it stays accurate. For SaaS support or internal tools, RAG is the correct choice. I will tell you which fits your case.
Do I own the source code, and do you handle hosting?
You own everything. Source code, API keys, and data all stay with you. I deploy on Vercel, AWS, Supabase, or your preferred infrastructure. I can handle full deployment as part of the project, or hand it off for your team to deploy. No vendor lock-in.
Can the chatbot work across website, WhatsApp, and Slack?
Yes. I build the AI core once and deploy it across channels. Your website widget, WhatsApp business number, Slack workspace, Discord server, or mobile app can all share the same chatbot logic and conversation memory. One system, multiple front-ends.
