A web-based ERP for large-scale agricultural farm management and related decision support systems. At this project for Agri-Esprit, I mainly worked on Geolocation interfaces for geometry edition of crop plots and live GPS-based tractor tracking interface (JavaScript with Leaflet, Node.js on the server, and PostgreSQL with PostGIS in the database). I also worked in on the back-end and front-end of this platform dashboard. It used D3/HighCharts for displaying data and the back-end generates the data created by prediction models obtained live from weather stations, temperature sensors, and pluviometers. By observing the dashboard, it is possible to optimize decisions regarding the farms conditions and automatically create work orders (e.g., apply pesticides).

A SaaS dedicated to equipment maintenance companies that allows for managing the maintenance cycles of the clients' fire extinguishers. This software is one of the few that follows the Portuguese standard NP4413 for maintenance of extinguishers, which ensures the safety of its users. The software permits generating several data reports, printing maintenance labels, planning daily maintenance routes or sending notification letters and emails to the clients. The project was developed in C#/ASP.NET.

Vroomz is a hotel reservation site for major events. This website serves events and provides a unique front-end layout for each one of them. There, I rebuilt the front-end/back-end in C#/ASP.NET. I built a front-end with dynamic styling options which allows for it to be adapted to any event. I also moved, transformed, and migrated an old MySQL database from the former system into a new SQL Server schema. Regarding the back-office, I completely rebuilt it, with huge speed improvements in data loading and displaying. There, I also refactored the reports. Finally, I did some fixes/patches in the former PHP system while the new system was not yet live.

In this project, users can store information about their financial products (bank deposits, stocks, risk funds, etc.). The system then gives the users detailed reports and notifications about the performance of their investments as well as recommendations about future investments. This project was implemented in C#/ASP.NET with the aid of Google Finance API and Bloomerg API for stock and risk fund rates automatic update.

It is the first multi ordering platform for catering services in Kuwait. It makes it easier to find and order catering services including food trucks, live cooking stations, special dishes and more. There I worked directly on their platform by building the front-end and back-end of some of their pages, namely for registering new caterers. The project was implemented in ASP.NET MVC.

This software was built for companies that sell products in vending machines. The software allows for reading the logs from those machines (in the standard EvaDts format) and validates the cashflow from their sales. Finally, it generates billing documents and processes commissions for the vending machines' canvassers. This project was implemented in C#.

An eCommerce website for a hardware repair company. This project also includes the management of the whole repair process that goes from the picking of the equipment to one of the repair centers and its final delivery to the customer. This project was implemented in C# and all the data is synced with the company's ERP system (PHC).

This project consists of a digital catalog for Android tablets serving door-to-door sales for supplier companies. The users can show the customers all products and then perform an order. This software is also used in fairs, so special attention was given to the rapid creation of orders. The software was implemented with Android SDK. All orders and product information is synchronized with the company's ERP system (Eticadata) and an eCommerce website.

This project manages the whole logistics process of the distribution of the Magalhães PC (http://www.mymaga.eu/) acquired by Meduca (Panama's education ministry) to distribute to students of all schools in the country. This project also manages the repair processes of possible malfunctions of those equipments. The project was implemented in C# and ASP.NET.

This is a ASP.NET MVC project built from scratch for a car stand. It is a catalog for cars and it has a tire order configurator so the clients can order the installation of new tires with ease.

My role in this project was to build almost the entire back-end (SQL Server database) and the back-office for inserting content in this website.

An academic publication in which I discuss the creation of a middleware framework for non-traditional game controllers (WiiMote, Rock Band instruments, Kinect, etc.) that addresses the issue of their not being designed for other game applications. The framework maps body poses or voice commands to actions in any game, providing a more natural and customized UX and thus potentially expanding the market of game consumers.

Prototype software that uses a Guitar Hero 3 controller to play real notes and chords by connecting the controller to a computer and mapping each button (or a set of buttons) to a particular note/chord. The sound was produced with a MIDI-like system that sounds more like the real instrument. Although the controller only has five buttons, it is possible to use a maximum of 31 different combinations and play real songs. This project was implemented in Java.

A three-dimensional business simulation game designed to be a massive multiplayer online game integrated with social networks. The objective is to build a city from scratch and try to address the many problems that arise from it (hunger, unemployment, pollution, etc). In short, the idea is to try to reach the eight Millennium Goals at this small scale and to try to realize the difficulties of it as well as to learn how to accomplish them. This is done by constructing and evolving roads and buildings, passing laws and measures, and establishing partnerships with other players. Each of these actions can contribute in many different ways to improve your score regarding the Millennium Goals' achievement. Imagine City is intended to be "non-ending game." The player's objective is to improve his city as much as possible and compete in a world's Imagine City Ranking.

This project was implemented in C# with the XNA framework for graphics.
