Commercial management system with a multi-tenant SaaS architecture, offering integrated control of sales, cash registers, employees, and inventory, complemented by a comprehensive auditing system and strategic management reports. Initially developed for a local store, the platform evolved to support the simultaneous management of multiple establishments and branches, with data isolation between tenants and robust authentication using dual JWT tokens (access and refresh), optimizing daily operations and increasing efficiency in business resource administration.

Interactive academic project focused on the practical application of Computer Graphics and Image Processing concepts. It implements 2D primitive rasterization algorithms, such as lines, circles, and polygons, using classical methods like DDA, as well as geometric transformations including translation, rotation, and scaling. The project also applies image processing techniques based on convolution matrices, enabling effects such as negative, low-pass filtering (smoothing), and edge detection, with real-time visualization for educational purposes.

Game developed in Java as part of a course discipline in the Bachelor’s Degree in Computer Science, inspired by the Habbo Hotel visual style. The project features customized characters, with the playable character wearing the uniform of Pernambuco (PE) state public schools, and enemies inspired by iconic pop-culture figures such as Ghostface and Jason. Although my primary focus is web development and research, this project pushed me out of my comfort zone, representing a distinct and unconventional experience during my early stage as a beginner programmer, and highlighting my ability to adapt to new and unfamiliar software challenges.
