  • (Development)

    This project involved building a platform that created a type of advertisement which shows up on a user's mobile phone based on their indoor location. We used beacons and technology called Google Physical Web to populate URL address directly to users' devices. The platform enables the configuration of the URLs with particular beacons and gathers stats about the usage. Thanks to the WYSIWYG editor, it's possible to create the content online.

  • (Development)

    This is an Angular-and-Play-Framework-based application which gathers in one place winter trip offers provided by different travel agencies. It also has advanced-and-efficient filtering and a minimal UX design.

  • Gymy (Other amazing things)

    This is an app that was created during a 24-hour hackathon—and won first prize—which helps people to train at the gym. It's based on indoor navigation using beacons and an Android app. It takes the user from one exercise equipment to the next one and even counts the reps.
