About the client

OPAP is one of the largest gaming organizations in Greece. This project covered the application running on OPAP Play terminals.

Project Overview

The work focused on rebuilding parts of the interface and gradually upgrading the frontend within the existing Electron environment. The UI had to remain stable and predictable on devices used continuously in physical stores.

The Challenge

There was no room for a big-bang rewrite. Changes had to be introduced gradually into a production desktop environment with real daily usage.

My Contribution

I worked on frontend components, UI flows and modernization of the existing application.

Technology Stack

  • Electron, Vue.js, TypeScript, frontend modernization, production terminal UI.
