Fullstack AI/ML Software Engineer Project

This repository hosts the Weather App, a robust full-stack application designed to provide real-time weather data and air quality information for any location—using a modern, user-friendly interface and a scalable, extensible backend.

Both Technical Assessment #1 (Core Weather App) and #2 (Advanced Features & CRUD) are fully completed and demonstrated in this project.

Built as part of an AI/ML Software Engineer technical assessment, this project demonstrates best practices in API design, user input handling, data validation, database CRUD operations, and optional integrations with third-party platforms (e.g., YouTube, Google Maps).

Key Value:

• Real-world API integration
• Clean, modular codebase
• Designed for extensibility and professional deployment
• Ready for demonstration, portfolio, or further development

• Universal Location Input:
  Search weather and air quality by city, zip code, coordinates, or landmarks. Robust validation and fuzzy matching for user convenience.

• Real-Time Weather & 5-Day Forecast:
  Live data from OpenWeatherMap, including detailed weather info, icons, and at-a-glance summaries.

• Air Quality Index (AQI) Data:
  Instantly retrieve current air quality information for user-selected locations, powered by OpenWeatherMap Air Pollution API.

• Geolocation Support:
  Instantly fetch weather and air quality for your current position—using your browser/device location (with user permission).

• Comprehensive CRUD:
  Save, update, view, and delete weather and air quality queries/records. All data is persisted in a robust SQLite database via SQLAlchemy ORM.

• Data Export:
  Export your search history or saved records to JSON, CSV, XML, or PDF formats with one click. Great for data portability, analytics, and reporting.

• API Integrations:

  • Google Maps: Visualize searched locations on the map.
  • YouTube: Watch trending videos about your searched location.
  • OpenWeatherMap Weather & Air Quality APIs

• Responsive & Accessible UI:
  Clean, mobile-friendly design with flexible color gradients and intuitive controls. Accessibility best practices followed.

• Error Handling:
  Clear, actionable error messages for every input and API call.

• No Authentication Required:
  All features are open for demonstration and review.

• Info Button:
  Learn about the Product Manager Accelerator (PMA) from within the app.

• Backend: Python 3.12+, Flask, SQLAlchemy, SQLite
• Frontend: HTML5, CSS3, JavaScript (ES6+), Jinja2
• APIs: OpenWeatherMap (Weather & Air Quality), YouTube Data API, Google Maps
• Utilities: Pandas (export), FPDF (PDF export), python-dotenv (for secure API key management)
• Testing: (Add your test framework, e.g., pytest, if implemented)
• Deployment: Easily deployable on Heroku, Render, or any WSGI-compatible service
