Hands-on Software Design

From principles to code

Building complex, heavyweight software is easy, but it takes practice and effort to move in the opposite direction to create pragmatic, lightweight design that’s extensible and maintainable. While experience is quite important, repeatedly doing the same things over and over may not present better results. You have to step back and think about the whys and then the hows behind the task you’re undertaking.

Join expert Venkat Subramaniam to gain better clarity on how to create designs for your applications, as he takes you through a very practical approach to creating lightweight design. You’ll start by unpacking the characteristics that are part of good design, then explore core design principles through a series of concrete code examples that best illustrate them.

APAC friendly time.

What you’ll learn and how you can apply it

By the end of this live online course, you’ll understand:

  • The characteristics of good software design
  • How to create design that is relevant instead of being frivolous

And you’ll be able to:
