A selection of my projects

I invite you take a look at some of my public projects.
Here, you can get a feel of what problems I am interested in solving, and what technologies I use to solve them.
You'll find a complete list in my public repositories.

A Java application running on Tomcat that pushes the live prices for cryptocurrencies to clients listening on a WebSocket.

An iOS app in SwiftUI using WebSockets to provide live prices for cryptocurrencies in a list and detailed view.

A REST API wrapper of using Express and Docker so that it can be deployed in the cloud and used by any client, rather than being bound to using the JavaScript API.

A Java web service to find the nearest UK train stations to your location.
This app demonstrates some primitive, raw Java techniques, such as using the native java.sql.* package for database interaction,* package for the web services, and self-managed dependency injection, showing what can still be achieved in plain, old Java.
