WhatsApp Virtual Assistant Development

Hi there!
I’m looking for an experienced developer (preferably with experience in WhatsApp API and automation tools) to build a virtual assistant that works through WhatsApp. The goal is to create a smart “secretary bot” that helps users manage their schedule and stay organized through daily WhatsApp messages.

Key Features:
• Initial onboarding with personalized questions (to understand the user’s routine)
• Daily messages reminding of appointments/tasks
• Weekly summary and feedback
• Mood tracking (optional feature)
• Motivational quotes or custom messages
• Easy backend or spreadsheet integration for updates

Nice to have:
• Integration with Google Calendar or similar
• Voice message options
• AI-generated feedback or summaries

Target user:
Busy professionals, students, and entrepreneurs who want to keep track of tasks in a simple and motivating way — directly through WhatsApp.

Platform:
Can be built using Twilio API, WhatsApp Business API, or similar tools. Open to your suggestions on tech stack.

Budget:
Please provide a quote for an MVP version and optional features separately.
