A Step-by-Step Guide to Improve Your Ruby Skills Today

If you learned the basics of Ruby but you still feel like you could be doing a lot better...

...if you don't feel confident in your Ruby skills...

...if you'd like to earn more, write better code & be proud of your work...

...then this could be the most important message you'll read today.

Hi,

I've been teaching Ruby for over 3 years & I'd love to help you become a better Ruby developer!

Would you agree that if your Ruby skills are lacking you're gonna have a hard time...

...understanding how things work...

...fixing things when they go wrong

... and solving real-world problems?

If You're Only Learning Ruby To Pass Time & Have Fun... Then This Isn't For You

But if you want to build a solid career, get paid & feel good about your work you need to take this seriously.

Here's how:

  1. Find out a list of all the topics you need to cover (things like metaprogramming & lambdas).
  2. Gather all the information from many different sources, filter through it to remove outdated & low-quality material.
  3. Study that information, hoping that you didn't miss anything important.

Sounds like a lot of work right?

Because it is!

Your Problem

When you understand Ruby better you'll be able to write better code, enjoy your work more & feel more confident.

The problem is:

It's hard to know exactly what you need to learn...

...and it's even harder to find all the information you need in one place!

That's why I invested over 100 hours of my time to put together a resource for you.

Here's What This Will Do For You:

  • You'll build a solid foundation of Ruby skills to help you become more confident so you can land that Ruby job
  • You'll ​close the gap between the fundamentals & more advanced concepts
  • You'll learn the tools, ideas & code examples that you need to understand things better

This is Ruby Deep Dive, the book for serious Ruby developers.

How You Can Stand Out In The Market Place & Get The Best Developer Jobs


Would you rather stand out & have fun with your work...

Or get seen as "another AVERAGE developer".

On the same level as all these Ruby developers looking to take on any boring, low-paid project because that's the best they can do.

Nobody wants to watch an average movie, or eat an average meal, or hire an average person...

We all want exceptional.

Companies are looking to hire exceptional developers. Exceptional stands out, average blends with the rest.

It's time to do something about this NOW...

... or get left behind in the average pile where all the boring stuff happens!

You choose.

But if you ask me I would recommend you take advantage of this...
