3. 💬 Take Home Challenge

• Description: The challenege was to build a scalable web application that generates personalized travel itineraries based on user preferences, such as budget, interests, and trip duration. Functionally, an ideal solution should offer a user-friendly interface for inputting preferences and deliver detailed, dynamic itineraries tailored to individual users.

• Difficulty Level: Medium - Hard

• Your Experience: It was a interesting problem to solve and the team really liked my submission. I approached the problem in the following way:

  1. First, I understood the problem statement and then started with the architecture or design of what my application should look like.

  2. I listed down the functional and non-functional requirements for the app and decided the tech stack I will be using to build this app.

  3. I first built the backend for it in Node.js following the Object oriented programming principles and for database I chose to use MongoDB as it is best suited to store the generated itineraries in a flexible format.

  4. For frontend, I utilized Next.js and Magic UI to create a user friendly application.

  5. Leveraged Gemini’s API for its AI Model allows for personalized itinerary generation based on user preferences. The AI can analyze user data, past behavior, and real-time information to create tailored itineraries that match individual interests, such as destination, trip duration, and budget, thus enhancing the travel experience.

  6. Integrated Google Maps API to visualize locations, such as hotels and places suggested by Gemini's API, adds a practical layer to the application. It improves the usability of the itineraries by providing users with interactive maps and directions, directly enhancing the travel planning experience.

  7. Used Redis for In-memory Caching and Rate Limiting APIs, Docker to containerize the application and additionally implemented CI/CD pipelines for integrations.
