Overview

I developed the "Hotel Booking System," a robust solution that simplifies hotel reservations through an intelligent chatbot interface. Leveraging AWS Lex for natural language processing, AWS Lambda for serverless backend logic, and Twilio for WhatsApp integration, this project enables users to book hotels in real-time via text-based conversations. This system showcases my ability to integrate cloud services and APIs to create a seamless, user-friendly experience.

Key Features

• Chatbot Interface: Built an intuitive conversational agent using AWS Lex to handle booking inquiries and confirmations.
• WhatsApp Integration: Integrated Twilio to enable users to book hotels directly through WhatsApp, enhancing accessibility.
• Serverless Backend: Utilized AWS Lambda to process requests and manage booking logic efficiently.
• Real-Time Updates: Designed the system to provide instant responses and booking confirmations.

Technologies Used

• Frontend: WhatsApp messaging interface (via Twilio).
• Backend: AWS Lex, AWS Lambda, Python.
• Integration: Twilio API.
• Tools: AWS Console, Git.

My Role

As the sole developer, I designed and implemented every component of this project:

• Configured AWS Lex to interpret user intents and manage conversation flows.
• Developed Lambda functions to handle booking logic and database interactions.
• Integrated Twilio to connect the system with WhatsApp for a smooth user experience.

Challenges & Solutions

• Challenge: Handling natural language variations in user inputs.
• Solution: Trained AWS Lex with diverse sample utterances and implemented fallback intents.
• Challenge: Ensuring real-time performance with serverless architecture.
• Solution: Optimized Lambda functions and minimized cold start delays.

Outcome

The "Hotel Booking System" delivers a practical, scalable solution that simplifies hotel reservations for users. It demonstrates my expertise in cloud-based development, API integration, and conversational AI, providing a modern alternative to traditional booking platforms.
