BookRental is one of the older projects covering several JEE aspects. Its aim was to create a library management system; namely, management of: books, loans, reservations, users and employees. The application implements more than 20 different business features. The main technologies used in the project are: Java, JSTL, JSF, PrimeFaces, JPA, JDB. The presentation of the application can be viewed in the gallery. At times, it does not look too attractive since it was created at the beginning of learning JEE and web technologies [2015] (check out Develog to see the difference).

Splash! is a multiplatform, raster graphics editor inspired by such programs as Photoshop, Gimp and Microsoft Paint. The idea while creating the application was to fill the gap between simple and intuitive Paint and advanced and crude Gimp. The application was written in Java using the Swing library. The main point though, was to learn and use in practice many different design patterns.
