I will build ai chatbot, ai agent or chatgpt integration for your website
Daniil Vasenkov
About this gig
Need a chatbot that actually knows your business? I build AI assistants that answer real questions, work on your website or messenger, and sound like your brand.
I'm a full stack developer (Next.js, React, TypeScript, Node.js, Python) working with OpenAI, Claude, Gemini and LangChain every day.
What I can build:
- Website chat widget that matches your design and tone of voice
- Bots trained on your own content: docs, FAQ, product catalog, PDFs (RAG)
- AI agents that book appointments, qualify leads and collect requests
- Telegram, WhatsApp, Discord and Slack bots
- ChatGPT integration inside your existing app or admin panel
- CRM, database, email and calendar connections
- Multi-language support and custom conversation flows
Why me:
- Clear communication and daily progress updates
- Full source code and your own API keys, nothing locked to me
- Deployment included, the bot goes live, not just to your inbox
- On-time delivery, no surprises
Message me before ordering with a short description of what the bot should do, and I'll confirm the scope and price.
Let's build it.

My Portfolio
FAQ
1. Who pays for the OpenAI or Claude API?
You do, directly. The bot runs on your own API key, so you control the account, the limits and the billing. For most small business bots the cost is a few dollars a month. I'll help you set the key up.
2. Can the bot answer questions about my own business?
Yes, that's the Standard and Premium packages. I connect your documents, FAQ, website pages or product catalog so the bot answers from your real content instead of making things up.
3. What do you need from me to start?
A short description of what the bot should do and who it talks to. If it should answer from your content, send the files or links. For messenger bots I'll need access to the platform, and I'll walk you through it.
4. Where will the bot run after delivery?
On your infrastructure. I deploy it to your hosting, Vercel or your server, and hand over the full source code. Nothing stays on my side and nothing stops working if we stop talking.
5. Can it speak languages other than English?
Yes. GPT and Claude handle most languages out of the box. Multi-language support with proper prompts and tested replies is included in Standard and above, or available as an extra.
6. My project is bigger than the packages. What then?
Message me first with the details and I'll send a custom offer with a fixed price and delivery date. Most of my orders start from a short conversation rather than a package click.
