    • WebFlow: Customized interface for partners and integrations.


Backend (Logic and API Management)

  • Frameworks:

    • Firebase for API management and real-time data handling.

  • Recommendation Logic:

    • LoRA (Lower Ranking Adaptation) for user-based activity recommendations.

  • Authentication:

    • OAuth 2.0 for secure and seamless social logins (Google, Apple).

  • APIs:

    • Payment Gateway: Stripe for managing secure payments and bookings.

    • Weather API: Integrating OpenWeatherMap to recommend activities based on real-time weather conditions.


AI and Machine Learning

  • Recommendation System:

    • Hugging Face embeddings for NLP-based user preference extraction.

    • Collaborative filtering via Matrix Factorization for recommendations.

    • KMeans clustering for grouping users with similar preferences.

  • Natural Language Processing (NLP):

    • Pretrained models from OpenAI (GPT) for conversational interactions.

    • NER (Named Entity Recognition) for extracting locations, preferences, and activity types from user input.

  • Real-time Personalization:

    • Contextual bandit algorithms to dynamically adapt recommendations.


Data Engineering and Storage

  • Databases:

    • Relational Database: PostgreSQL for structured data (user profiles, bookings, preferences).

    • NoSQL Database: MongoDB for unstructured data like search histories.

  • Storage: Google Cloud Storage for travel-related media (e.g., activity images, itineraries).


Infrastructure and Deployment

  • Cloud Platforms: Google Cloud Platform for scalability and reliability.

  • Containerization and Orchestration: Kubernetes for efficient deployment and scaling.

  • Load Balancers: Google Cloud Load Balancing to handle traffic efficiently.

  • Serverless Functions: Google Cloud Functions for lightweight tasks like webhook processing.


Model Serving and APIs
