Purchasing Power is a web application that provides tools to understand the changing nature of a currency's purchasing power over time and the impact those evolutions have on simple investment projections. The application contains a database of Consumer Price Indexes (CPIs) gathered from official sources and covers 36 countries (EU and US).

The application is composed of four services:

• ETL: fetches the data from Eurostat, the US Bureau of Labor Statistics, and REST Countries and loads it into a PostgreSQL database hosted on an AWS RDS instance.
  • Python, Docker.
  • Runs punctually on the local machine.
• Enrichment: normalizes the data in the database.
  • PostgreSQL, Python, Docker.
  • Runs punctually on the local machine.
• Backend: uses the database and some (tested) logic to provide data to the frontend.
  • Python (FastAPI), Docker.
  • Runs on an AWS EC2 instance.
• Frontend: displays the data to the user.
  • React, Vite, Docker
  • Runs on an AWS S3 bucket.

This is a monorepo: all services are in the same repository. Also, each service has a README with specific technical instructions.
