Looking for a specialist to create an AI chat assistant for a sushi bar.
115 USD Task (MVP): create a smart assistant for the website (chat widget) + Telegram/WhatsApp, which:
answers questions about the menu, ingredients, and allergens;
informs about promotions (including offers to specific clients: when ordering from €50 — for example 15% discount);
helps to collect an order (cart) and performs upselling (sauces, drinks, mochi, etc.);
collects client data: city, address, entrance/floor/comments, name, phone, mandatory postal code and area/district;
can transfer the dialogue to an operator if needed..
Languages: RU / EN / GR / UA — respond in the client's language (offer to change the language).
Platforms: website (chat widget), Telegram, WhatsApp. Voiceflow, Make.com, Zapier or custom (Node.js/Python) will work — suggest a stack.
Integrations (stage 2, optional):
Identification of authorized clients on the website (by name). If the name is incorrect - suggest updating it, in a friendly manner..
Pulling order history from Poster POS (REST API): “Hello, Andrey! How was your day? Shall we repeat the last order?”
What is needed as a result:
A working MVP bot with a knowledge base (menu/allergens/promotions), manual editing (via JSON/Google Sheet/small admin panel — suggest an option).
Upselling logic and checking if the total is ≥ €50 → 15% discount.
Hand-off to an operator.
Deployment instructions, short documentation, 10 test dialogue scenarios.
Acceptance criteria:
Correct multilingualism, short replies, one question at a time.
Clear fixation of the address with postal code + area/district.
Accurate answers regarding allergens (if unknown — polite refusal and alternative). It needs to be trained on everything available on the website, ingredients, allergens, rules, etc.
Simple content support (menu/promotions updated without a developer).
Ideal experience:
Voiceflow, Make.com, Zapier / Telegram Bot API / WhatsApp Business API.
Integrations via webhooks/REST, experience with POS/CRM (preferably Poster POS).
Experience with GDPR/privacy (EU).
From you in the response:
2–3 examples of similar bots (links/screencasts).
Briefly — proposed stack and why.
Timeline for MVP and budget (fixed/hourly).
How you will handle menu/promotions updates without developer involvement.
Experience with Poster POS (if any) — a plus.

Your project is not just a bot. It is a full-fledged digital waiter, consultant, and marketer who knows the menu better than any manager and doesn't forget about the discount after €50.
💡 I don't just "make chatbots" — I build living dialogue systems that breathe business logic. Your assistant will:
respond to menu and allergen inquiries with medical precision (if unsure — politely suggest an alternative);
gently nudge towards upselling, like an experienced barista who adds sauce and mochi without pressure;
collect address and postal code with the accuracy of a Glovo courier;
switch to an operator at the right moment without losing context;
speak with the client in any language, even Greek 🇬🇷
🧠 Technologically — this is a hybrid:
… Voiceflow + Make for quick and clear logic;
Google Sheets / JSON — for editing the menu without developer involvement;
Telegram + WhatsApp API — a ready multi-channel connection;
Poster POS REST API — we will connect it if needed to find out the client's favorite dishes.
⏳ MVP can be launched in 2–3 weeks.
💶 Cost — from €3K, fixed, including documentation and 10 test scenarios.
Do you already have a menu and a list of allergens in structure (CSV/table)?
If you are ready — I will show you how the assistant not only responds but sells, remembers, and charms.

… • Front: custom chat widget (React) + Telegram Bot API + WhatsApp Business API.
• Integrations: REST/Webhooks → Poster POS, CRM, Google Sheets.

📌 How menu/promotions updates will be handled

2236 46 0 15 days917 USDGood afternoon. I will do it in Python with the LangGraph library + RAG as a knowledge base.
The user asks a question, the system searches for similar materials, and sends them to the LLM for an answer. The AI receives the question and materials and generates a response. The dialogue is saved while the conversation is ongoing. The system periodically visits the website and updates the data, or it can be done by a button. I am not familiar with the CRM you mentioned.
Furthermore, we can also add identification and checks here.
