I am a student of Computer Science. I know several programming languages such as C, C++, C#, Dart, Java, Python and Javascript; in addition to other markup or style languages such as HTML, CSS and JSON. I really like both mobile application development and web application development, using frameworks, software, technologies, etc like Android Studio, Flutter, Unity, Flask, Vue.js and Bootstrap.

In my free time I am always researching and learning about new technologies, frameworks, etc. I am good working both individually and as a team, I know the development methodologies of agile software and tools like Git.

Cuba Weather

Cuba Weather is a pioneering, open-source, cross-platform, non-profit project in Cuba, the goal of which is to provide residents of Cuba a convenient way to access weather information obtained from national sources using only national navigation (for example, the voucher 300 megabytes of national data packets). A little over a month ago, Apklis has reached more than 28 thousand downloads, several reports in digital media, a great contribution from users through suggestions and donations, collaboration and advice from INSMET specialists and improvements implemented by various developers creating in shortly an enthusiastic community around the project.

Assessment of gait using inertial measurements units

Abstract: Gait patterns undergo a natural modification throughout life, which may include the occurrence of gait disorders due to aging and different pathologies. Its analysis allows the evaluation of physical performance at different ages and it is a predictor of the risk of falls and cognitive impairment in older adults. The clinical eval-uation of gait is usually performed in laboratories, but there is a promissory alternative by the use of Inertial Measurement Units (IMU), portable devices for recording gait patterns in ambulatory environments. This paper presents a methodology for recording and assessing the gait patterns using Bitalino RIoT, an IMU that records acceleration, angular velocity and magnetic field signals in three axes. It was placed in the lumbar region of the 80 subjects included in the study, at the level of L1 vertebra, adjusting it firmly at the waist. The subjects walked 40 m in a straight line, 20 m in each direction, executing different types of walking.
