- Centralized AI Communication Hub: Developed a cross-platform interface unifying WhatsApp, Messenger, Instagram, and LINE into a single interface. This allows businesses to manage all customer interactions without switching platforms, streamlining support and sales workflows.
- 24/7 Automation with Smart "Auto-Off" Logic: Built an AI-enabled system for 24/7 instant customer engagement. Implemented logic that automatically turns off the AI chatbot whenever a customer service representative begins replying, ensuring a seamless transition from AI to human support.
- Automated Appointment Reminders: Engineered a background task system using Celery to send automated reminders to clients for booked appointments, improving scheduling efficiency and reducing missed bookings.
