About the project

Tools Portal is a collection of internal tools built to support different operational tasks and make everyday processes easier to manage.

One of its main applications is Booking Admin, designed for travel agents to view, manage, and process bookings made through the booking system.

The portal is built on Ruby on Rails 8.1, and applications across the client's ecosystem are hosted on a combination of on-premises infrastructure and Google Cloud Platform.
