Zentrex is a small sole proprietorship owned by my brother. The company's an allround IT specialist and does work from repairing smartphones, tablets and computers to selling equipment.

I did two projects for Zentrex. The first one being logo and business cards design, the second one being an invoice manager. This invoice manager is a web application to easily generate pdf invoices. It has a backend that stores customers and types of expenses so they can easily be filled in through dropdown menu's in the frontend. The entire layout and content of the pdf can be customized by editing a template file. In the template some syntax can be used to automatically fill in customer info, expense data and cost.
The frontend was made with Angular, the backend with Node.js, Express and MongoDB.

The code for the invoice system can be found on GitHub in the Invoice Manager repo for the frontend and the Invoice Manager Backend repo for the backend.
