Motivation

I wanted to show case my problem solving abilities by using optimal algorithms for large scale and distributed applications, in this case a URL shortener app.

The code also showcases:

• SOLID principles ✔️
• Code best practices ✔️
• Database indexes ✔️
• Caching ✔️
• Automated tests with Rspec ✔️
• API only mode provided by Rails for fast responses ✔️
