He estado trabajando en investigación y desarrollo de software desde 2008.

Unless I say I'm speaking for my employer, I'm not speaking for my employer.

The following is an attempt to convince you that I’m an awesome person doing extremely interesting things.

I graduated from the University of Informatics Sciences (in Havana, Cuba) in 2009.

Private

  • In 2013 I developed a puzzle game for a local client using Qt/C++.

  • In 2014 I did a few web development and support tasks for Jimenez Solutions mainly using Joomla and MySQL.

  • Since 2014 to the present, I have been involved (requirements, programming, testing and deployment) in the development of LabraS for INICA, a planning software for agriculture.

  • For an Italian client, in 2015 I, as part of a team, fixed many issues of an existing website developed with Yii1. For the same client, as part of a team again, developed an entirely new web application using Yii2 and MySQL. The project involved many third party API integrations.

  • For a local start-up, I developed an Android app (2016) using SQLite, QML, Qt and C++. One technical challenge was to encrypt/decrypt the SQLite database in order to keep customer's data save.

  • In 2016 I participated in the developement of a desktop accounting software for a local SME using QML, Qt and C++.

  • In 2017 I developed an Android app for a local client using QML, Qt and C++. The information exchange between the app and the outside world was through SMTP and POP e-mails protocols.

  • Desde 2017 he estado trabajando para Owls Web Design y BrandIgniter como desarrollador web.

Public

  • Founder and main developer (2009 - 2011) of the Cazabe project, a FLOSS replacement for Macromedia/Adobe Flash written in Qt/C++.

  • In parallel, I created the XML based .cz file format (to save flash projects done with Cazabe) and developed the cz2swf tool (Bash and C++). This tool creates a .swf movie from a .cz file using libming.

  • Since April 2017 I am working on Enigma, an encrypted SMS/MMS client for Android written in Qt/C++ and Java.

  • I also write articles about programming, security and society. I don't play ads on my blog.
