As software developer I also have some technical projects.
A collection of valid, useful and enjoyable examples about Java, hosted on GitHub and released under the very permissive MIT License.
A single Maven based project containing a set of demos about the new Java 8 Stream API, hosted on GitHub and released under the very permissive MIT License.
A section of my site dedicated to provide technical documents about Java and programming in general. All these documents are exclusively developed by me and are available for free and for whatever use you want, according to each document's license.
