Xamarin Introductions

Introducing Leomaris Reyes

This week's featured community hero is Leomaris Reyes from Dominican Republic.

Tell us a bit about yourself?

I’m ​Leomaris Reyes, Software Engineer from the Dominican Republic, with more than 5 years of experience in Software Development. Xamarin Certified Mobile Developer. I’m also vice president of​ Mujeres Tics​ Community and Microsoft MVP.

Tell us one thing we probably don't know about you?

In my free time I enjoy drawing. I really love dancing and I love green spaces.💚

How did you first get into Xamarin development?

By working with web and desktop technologies. Also I was very interested in learning about mobile technologies as well, then I started to see native and multiplatform development existing options, I discarded the native option because I felt that I was a bit incomplete just by learning one and if I learned more than one native the learning curve would be longer, at that time I’ve heard from Xamarin and realized that the learning time was much less, because I already knew to program using C # and I could work with "Two in one" (Because I would be working on all the platforms I needed at the same time), it was that way back when I started studying until I totally felt in love with Xamarin!😍

What has been the most enjoyable project you have built using Xamarin?

One of the projects that made me feel very proud of the work done was the implementation and testing of a Facebook plugin in which I had the opportunity to be an open source collaborator. It filled me with pride, because at the time I developed it, I was totally NEW in the Xamarin world.🙈

What advice would you give someone looking at getting started with Xamarin development?

Xamarin is a very nice tool, I invite you to discover for yourself how powerful it is, all the beginnings are difficult, the most important thing is not to get discouraged and learn all the way. You can start with ​ Microsoft Learn and since the community is so cooperative and amazing you can check the different blogs that exist!

In my case, one of my techniques of each topic learned was to have a kind of "Library" where anything could come back and refresh what I learned, this is where my blog comes in, everything started being a place where I explained and saved what learned and at the same time other persons learn with me.

I wrote an article with recommendations for you to practice XAML, because sometimes we can’t find a way to apply what we’ve learned (If we are not working in the area yet):

And if you encourage yourself like me, to let your knowledge help other to learn (Creating your own blog), here I leave you this article!

What are the MUST HAVE tools, resources and libraries that you use when building Xamarin apps?

  • Xamarin Essentials :
  • Prism:
  • PropertyChanged.Fody:

Where do you think mobile will be in 5 years?

It will be used by more people and will continue making great contributions to the humanity. 😎

Any other things you would like to share or promote? I wan to present "Mujeres Tics", it is the largest community of girls in technology in the Dominican Republic 🇩🇴, which I have the opportunity to lead with a wonderful board, we work with the main objective to inspire, motivate, train and include more girls in technology. Website: Facebook:

Also, if you want to read great articles in Spanish I invite you to enter to Xamarin Latino. (

And finally on Fridays I invite you to see the .NET Friday Show, a program in Spanish based on .NET technologies. (
