Toward the end of 2014, one of our great developer evangelists, Kunal Batra, took on the challenge of learning 15 new technologies and blogging about them in a Code Challenge series.

The Code Challenge series was a great way for Kunal to experiment with new technologies and provide readers with some great new tools and introductions to software they may have been unaware of.

Now that some time has passed since his last post in January, we’re looking back on the most popular Code Challenge blogs. Below are the top five posts based on number of visits:

5 – Learning Swift – This post is an introduction to Apple’s new coding language. Kunal shows exactly what you need to get started coding in Swift and even provides a great video as a resource.

4 – Storing your Incoming Emails with Orchestrate.io – Orchestrate provides a “database as a service” for users storing different types of data that needs to be retrieved in specific ways. In this Code Challenge post, Kunal shows you how to set up an Orchestrate database and then store your incoming emails in it with the Parse Webhook.

3 – The SendGrid Event Webhook and Firebase – To create an icon on his Mac that drops a real-time feed of updating email events, Kunal uses Firebase, the Event Webhook, the Google Compute Engine, and the OSX menu tray application.

2 – Creating a Black Friday Mashup with Kimono and SendGrid – Originally written to help him track Black Friday deals, Kunal uses the Kimono Labs API and SendGrid to create a new API that sends an email every time a deal changes.

1 – Building a Hello World Apple iWatch App – Kunal’s most popular Code Challenge post was about creating a simple app for the Apple iWatch. This post goes hand-in-hand with the first post in the list, Learning Swift. This post includes a video and walks users through creating an app for the iWatch that displayes the text “Hello World” when a button is pushed.

These are just the most popular posts from this series, but Kunal and our other great developer evangelists work hard to provide great technical content all the time. Check out Kunal’s introductory Code Challenge post for all the technologies he worked on.
