Experience

Music Streaming App for Businesses

https://musmus.ge/?lang=en

I owned the development of the entire product suite for MusMus, a music streaming application proposed by the Georgian Copyright Association to allow Georgian businesses to play copyrighted music in public spaces.

I developed the web app, the back end, and mobile apps for iOS and Android from scratch. The player has playlists, ads, offline playback, and most importantly, the radio feature, which enables branch managers to create a weekly radio schedule that will ensure synchronized playback between business branches with an accuracy of one second.

I'm very proud of our final product, but what makes me really honored is knowing that any time I walk into a supermarket, a store, or a restaurant, the music that I hear comes from the player that I created.

Professional Network for the Hospitality Industry in Italy

I developed the mobile apps and the back end for F&B, an Italian professional network for the food and beverage industry.

The application allows employees, employers, and educators of the food and beverage industry to create profiles and connect with each other. The application provides geolocation-based search results for jobs and courses, an advanced CV maker, and an integrated chat between users. Every time jobs and courses are added, the platform finds matching candidates within an area specified by the business and notifies them about that new opportunity.

File Hosting Cloud Platform

I founded a file hosting cloud platform that allows users to interact with the cloud using a desktop interface. The project received a seed fund of USD $35,000 from the Georgian government.

This was a challenging project, spanning different technologies like PHP7, Node.js, HTML, JavaScript, MongoDB, and MySQL. I worked on exciting features such as storage deduplication, file encryption, streaming of encrypted media, file-sharing, permission management, virtual file systems, in-files search (Apache Lucene), and real-time file collaboration.
