About

Hi, my name is Lionel, I'm a full-stack developer. Over the past few years, I had the opportunity to develop solutions for several companies, start-ups, and small businesses. During these years, I made applications for the web and smartphones. These years helped me to acquire experience and a certain ability to adapt and learn faster.

I studied at Microverse , an online program which allowed me to acquire professional skills in web development, and collaborative and remote work. Now I work remotely with companies from all over the world. I am currently specializing in web development to build amazing software solutions for you.

[Ruby on Rails] : Build your first API using Rails

I would like to share with you my latest experiences with Ruby on Rails, especially the creation of APIs. This may already speak to you. If so, that’s good otherwise let me introduce you to this pretty little world. Lately I had to work on a few applications using the Ruby on Rails framework. Regarding the creation of APIs with Ruby on Rails, I must say it is rather interesting. Being a framework, it remarkably facilitates the life of the developer.
