I was considering focusing on learning RoR and looking for a work that uses those techs.

After some investigation, I decided to stay with C# .NET:

• It is more requested on job positions (7 to 1 in my personal searches average).

• It's been around for longer.

• it has better documentation and community.

• One of Ruby advantages (its amazing community gems, that allows to quickly build parts of your systems by merely putting together third party components) gets quite complicated to use and maintain in huge applications, where building and reusing your own components may become a better approach.

• Rail's front end support is starting to waver.

• C# .NET code is far easier to understand, debug and maintain. Although certainly not easier to learn from scratch.

• Though Rails has an excellent programming speed, C# tends to get the upper hand in long term projects.

I would avise to stick to rails when building small projects, and switching to C# for more long term ones.

Opinions are welcome!

Decided to change all my stack to microsoft technologies for they behave just great together. It is very easy to set up and deploy projects using visual studio and azure. Visual studio is also an amazing IDE, if not the best, when used for C#, it allows you to work in every aspect of your software.

Visual studio templates for ASP.NET MVC are the best I've found compared to django, rails, laravel, and others.

Node Js have worked incredible great for me on every project I had. It is fast enough to support big and small apps, you do not have to worry about performance, because it is very capable of building a big REST API.

One advantage is that the learning curve is lower when you have used javascript on web browser as frontend, so, it is easy to migrate from Frontend to Backend with node.

Node Package Manager (NPM) has an incredible amount of packages from many developers, so you can use them on your project as you need them.

Code is easy to support, way different than Java Legacy code.
