The Clean Code Architecture was introduced by Robert C. Martin on the 8light blog. The idea was to create an architecture which is independent of any external agency. Your business logic should not be coupled to a framework, a database, or to the web itself. With the independence, you have several advantages. For examp...
No one hates robust and scalable applications, especially when the database is growing quickly, and millions of requests need to be served on a daily basis. Profiling is a form of program analysis to measure the time and resources consumed by the program. With profiling, we can spot the performance bottlenecks in the c...
Product teams in startups and mid-sized and large companies are all implementing usability testing and prototyping as a way to de-risk product development. As the focus shifts from engineering to prototyping, it is becoming increasingly important for anyone who creates prototypes to understand the di...

A frequently used development workflow in version control systems is feature branching. The idea is that we develop new features in branches other than the master one. After a feature is tested and ready to be released, it is merged back into the master branch or a release branch for deployment. This approach helps us ...
The incredible growth of mobile and the proliferation of mobile devices has made the UX designer’s job more challenging and interesting.

I thought the use-case was particularly interesting: re-architectin...
It was the summer of 2013 and I was working on a project for my employer, Box. I had just finished wiring up JSDoc as a nightly build using a plugin to detect T3 patterns in our code and document them automatically. It occurred to me that these patterns might be easy to get wrong, and I started looki...
For many months, your entire team has worked their butts off to create an awesome mobile app. Finally, with your team exhausted and excited, it’s showtime! But then, your dream app turns into the ultimate nightmare: Eager customers download the app, use it once and never return. All the sacrifice a...
Promises are becoming a common part of JavaScript code. The native Promise object is already supported by all the major browsers including Chrome, Firefox, and Safari.
