Water Park Ticketing & E-Invoicing Platform

A Java/Spring platform deployed on AWS to sell tickets, enforce daily capacity, process online payments, and issue fiscal documents automatically.

Problem

The park needed online ticket sales without exceeding capacity on any date, plus a dependable flow connecting payments, electronic invoicing, and accounting exports.

What I built

I designed and implemented the backend, availability rules, Plexo payment integration, and post-payment automation, then deployed the containerized platform on AWS.
