Initially, we built desktop version based JavaSE, and later we changed it to web support application written in JavaScript/Node.js and React.js. In the web world since 2011. Started with PHP (Yii1/Yii2) and Java (JSF, Spring, Hibernate), and later switched to use JavaScript (Node.js, Vue.js, React.js, Rx.js).
