  • (Development)

    The first and probably the only wedding website builder in Slovakia. I developed the back-end using Ruby on Rails and a co-founder handled the front-end. We put too many features into our MVP and some users ended up having problems we would never imagine, but over 300 couples created their websites using our service.

  • (Development)

    Website that aggregates daily menus of student canteens in Bratislava with almost 5,000 unique visitors/month. I learned a lot about the importance of marketing and SEO on this project.

  • (Development)

    Website aggregating and visualizing statistics about Internet domains in Slovakia. The application also used to crawl all the Slovak domains and analyze which frameworks and libraries power them. I did some worldwide statistics by using a sample of 3 million domains. This was my first Rails project.

  • Master's thesis (Development)

    Researching ways of collecting and storing user data in an application to organize scientific papers. I developed many useful features to internal university projects like integration with external services (Mendeley) or natural language processing APIs.

  • OwNet (Development)

    The application aims to help schools with poor Internet connectivity get better access to the web. It works as a multi-platform proxy server that caches and preloads web sites. I built a Ruby testing framework for the proxy server and developed multiple features such as local network synchronization or automatic updates.

  • Bachelor's thesis (Development)

    This project focused on implementing scrapers of public data in Slovakia and researching ways of integrating them. I implemented scrapers for government websites in Ruby and a framework for experiments with machine learning in Java. Later, we provided the software to an organization watching transparency in Slovakia.
