AI Assistant with OpenClaw Architecture

Job ID: 40276107

Budget: $250 – $750 USD

Hi,

I am looking for a developer to build an MVP of an AI agent system inspired by OpenClaw architecture.

The first version should focus on a WhatsApp AI assistant that can communicate with leads, qualify them, and automatically book appointments.

Main requirements

• WhatsApp Business API integration
• AI conversation agent (LLM-based) that can respond naturally and guide the conversation toward booking
• Calendar integration (Google Calendar or Calendly) to schedule appointments automatically
• CRM integration to create/update leads
• Human override (ability to take control of the conversation)

Expected volume:
~50 new leads per day
~100 messages per day

Architecture requirement

The system should be built as a modular AI agent with a tools layer, so it can be expanded later into a full OpenClaw-style autonomous AI system with additional tools and integrations.

Example architecture:

WhatsApp → Webhook → AI Agent → LLM → Tools (CRM, Calendar, Messaging)

Suggested stack

Python (FastAPI)
OpenAI / Claude
PostgreSQL
WhatsApp Business API
Docker

Please include in your proposal

• Short architecture outline
• Tech stack
• Example of a similar system you built
• Estimated timeline and cost

Target MVP timeline: 1-2 weeks
