Insanely Simple Organization

When you first start off trying to solve a problem, the first solutions you come up with are very complex, and most people stop there. But if you keep going, and live with the problem and peel more layers of the onion off, you can often times arrive at some very elegant and simple solutions.

Steve Jobs, Newsweek, 2006

Enterprise Architecture

Can get needlessly complicated

Separate Concerns

  • Client vs API

  • Controller vs View

  • MVVM vs MVC

*Orange represents business logic

Legacy vs New

*Orange represents business logic

Agile Done Right: Using JavaScript and Node

By Doguhan Uluca

Agile Done Right: Using JavaScript and Node

Agile development is difficult. Teams can often miss their delivery goals, unsustainable pace can result in developer fatigue and technological bottlenecks can make it impossible to deliver a sane and high quality end product. When done right Agile can enable your team to deliver consistent forward flow of features in a sustainable manner. To achieve this goal you must use technologies that discourages skill silos, are easy to work with and allow for straightforward application of Agile Engineering Best Practices. JavaScript and Node.JS are the perfect set of technologies that can organically grow within your organization and existing code base utilizing a RESTful architecture. With JavaScript being the language of the web and the web, the OS of this decade, it is essential to effectively utilize these technologies to unlock the full potential of your team, allow for greater flexibility and reduce risk.
