Scalable Software Design | Christian Hujer

In this session, presenter Christian Hujer builds a program which can convert temperature from one scale (like Celsius) to other scales (like Fahrenheit, Kelvin, Rankine and more).
He builds the program with TypeScript and Kotlin, demonstrating the similarities and uniqueness of different programming paradigms. He also showcases how good coding practices can help you create clean, lean and scalable software design.
