Enthusiastic, responsible, dedicated to work and passionate about computer science in general, especially about software engineering, blockchain development, and teaching. In addition, I have a proven ability to lead, manage and develop a wide variety of projects in a team and independent situations. Teaching is my other passion!. I help software engineers grow, learn to write better code, and reach a productive and sustainable pace through continuous refactoring of their code and organization .

Latest Projects
Automatic Question Answering System (KGQA)
An efficient and effective automatic question answering framework, written in Python, that leverages data from any knowledge graph that provides high quality answers for open domain questions
New
The work about this question answering framework, and its architecture has been published by IEEE, and was presented in the IEEE International Conference of Web Intelligence in Santiago, Chile. You can find a copy of the paper below
Current Features:
- Supports Google and Diffbot Knowledge Graphs as data sources. I'll add more Knowledge Graphs support in future versions
- Provides high quality answers to open domain questions in an average time of 23 seconds
- Can be installed in any app that supports Python modules
- Multi-query generation
- Modular and scalable
- Much more... and more to come.
Customer Product Predictor (CPP)
An open source module contribution to Drupal.org which provides automatic evaluation of the comments made by customers about an order or product purchased through Ubercart e-commerce module.
New
Customer Product Predictor (CPP) is a set of modules designed to allow you to run prediction features on your Drupal site in order to predict the probability of a customer buying your products based on the latest artificial intelligence algorithms and tools. Development has been driven by two major emphases: flexibility and usability. So far, we have launch the core module of this product which is fully functional and independent of future releases related to this product. Also, we have launch the module CPP Ubercart which automatically evaluate order comments made when your customers buy a product using the ubercart module. CPP Module provide custom hooks that are fired when a automatic evaluation of your order is made. That's it, we are building a scalable and flexible system which administrative interface, particularly relating to the configuration of your data and its related permissions has been designed for ease of use and efficient display of information. For more details, be sure to visit the What is CPP? page for more info.

Current Features:
- CPP includes CPP Ubercart module
- Supported by Drupal 7.x
- Automatic product and order evaluation based on the comments left by the users who have made a purchase
- CPP custom hooks to promote your products based on a user evaluation order. Useful when customer is not happy about our product or order
- New CPP email api to make communication between your company and your customers easier
- Drupal administration components such as CPP settings and detailed product-order automatic evaluation table
- Activity logging
- Much more... and more to come.

Easy Remote Push Notifications
A Framework Where Developers Can Manage, Send and Schedule Remote Push Notifications for IOS and Android Devices. Easy Remote Push Notifications provides IOS and Android developers with an easy mechanism to sent unlimited remote push notifications to any of their application users. This service also allows developers to manage device tokens and schedule their push notifications.
- The server side of this project was developed in Swift, Java and PHP to provide functionality to all IOS and Android devices. The client side was developed using HTML5, CSS3, Javascript, JQuery and Ajax
- Build and Designed a remote server and API to help developers to send remote notifications to IOS and Android devices.
- Built a web site to Integrate the remote server and provide developers with direct access to their projects under secure registration and configuration
- Devised algorithms to keep developer certificates up to date before they expire
Carrusel KidsCare Calencar - Freelance project for a school Built and Designed for IOS and Android devices and published in Apple Store and Google play
- Builded and designed an object oriented remote server using JAVA and PHP technologies to support client requests comming from IOS and Android devices
- First the app was designed and Build for IOS devices using Objetive C, and later updated to Swift by client request to improve the sustainability and scalability of the project
- Helped the client to reduce development cost when creating and designing the Android version of this project by using the same server capatibilities and same functionality as the IOS version.
- Redisigned project front-end to meet Android version specifications
- Reduced delivery expected time by making sure that the project met all the guidelines specified in Apple Store and Google play in order to avoid project rejections
RSACE - Plug-in Designed for Eclipse
Rsace is a plug-in tool for Eclipse's developers. It provides an interface that allows developers' teams to work together in the same document, interactively and in real time.
Contributed to FlareMediaPlayer - A Multimedia Streaming Framework
FlareMediaPlayer is a client/server tool that once installed in your website or server provides a mechanism for your users to stream media files without any codec restriction. It takes a codified media file, and parse its video and audio. So, once parsed, the media file can be reproduced without any codec restriction in any of the actual web brownsers. This tool is very useful for companies which want to provide media services to their users across all the existing web brownsers.
