I am currently developing the e-SIWES online platform for Covenant University students and staff that participate in the industrial placement program using PHP, CodeIgniter, and AJAX. You can view the progressive web application here.
I developed a simple Tic Tac Toe game using Java for desktop and jQuery for the web. You can view the source code for the java application here, and the source code for the online version here
I built a bot on Twitter to promote my blog using NodeJS with a few other dependencies. You can view the source code here.
Other projects include a rock paper scissors game and a simple android app geared towards fitness both developed with Java, and others developed with JavaScript and JS frameworks like ReactJS. You can view the repositories here
