A satisfied customer asked us to create new web and mobile apps for their limousine service company. I am really proud of this project because I was responsible for literally everything and I built it all from scratch.

This included the following:
• Back end in Ruby on Rails, PostgreSQL, and more
• Front end in HTML, React, and such
• Mobile apps for both the clients and drivers (React Native)
• Website for the dispatchers, servers
• Project management and customer communication

This project was a mission-critical application—it had to work 100%. Otherwise, an important client pickup mistake could happen and potentially turn into a major problem for the limousine company.

As part of my full-time job, I work on this legacy Ruby on Rails application. I implemented a number of new features, fixed many bugs, and optimized the performance. I was responsible for both the back-end processing of the real-time GPS data from the hardware devices in cars and the users' front-end interface (Ext JS).

This is a mission-critical application with over a thousand monitored cars and hundreds of customers using it in real-time.

I created and managed a site for all types of accommodation facilities in Slovakia; facility owners could add their hotel, guesthouse, etc. and then tourists could select and contact the owners directly to arrange a stay.

I created a website that was filled with tourist attractions and things to do in Slovakia. It became quite popular and received many visitors during the holiday season.
