Currently we have a few projects not yet connected together for the line of chess-related projects.
Online chess games project:
1) user interface is implemented with jQuery, some free chess board component;
2) it talks to backend via Websockets where chess players can play a game and other users can watch that game online;
3) more technologies used there: REST, java 8, Payara, MySQL database, Hibernate, CDI, Maven;
4) for security we use first version of our internal registrator project.
Game analisys project:
1) currently it consists of set of tools for development PGN chess game databases and other tools;
2) the idea to develop this project is to give efficient chess game analisys like stockfish does. Or even better and/or provide more unique features.
Connection of these chess-related project will create a more powerful product eventually.
