Experience

Find My Dog

The goal of this application was to improve the security of the dogs. Using the application, the user could demand a collar for his dog and register it. While the dog was wearing the collar, the owner could see his actual position.

I developed the web and mobile applications using React for the front end and Hasura for the back end.

Data Analysis App

An application developed in Angular and migrated to React based on making connections between many databases and generating specific reports. The user had to select the right connections and specify the fields to create a report.

Theme Creator

A web application that was developed with the idea of implementing a new theme from scratch using Bootstrap. The user could modify the style of all elements on a website, including colors, margins, spacing, font sizes, and font styles. The user could also see these changes in real time.

Hotels Management

A web application that solved the communication issues between a manager and other employees. Using this application, the manager created specific tasks for every hotel employee so the employee could see what tasks had to be done every time. When the employee finished the job, a report was made. Based on that report, the employee received a bonus on salary.

Augmented Reality Practices

A game developed in Unity 3D that uses Kinect for augmented reality. The gamer can build a stair in the virtual world using tools and specific real moves managed by Kinect. The game is over when the user finishes the stair.
