Below is the selection of online projects I was responsible for.
Most of them were created personally by me or by my team with the exception of UI and some common components,
others were improved beyond the point of recognition.
Presented screenshots demonstrate functionality provided by the final products.
While they all appear neat on the outside, each project internally is a complicated system
dealing with gathering, filtering, aggregation, clustering, storage,
online searching and ranking of all imaginable sorts of data.
