The Rhea and Mark Inventory System is a computerized inventory management system developed using COBOL, designed to assist a small fruit business in organizing and managing product records efficiently. The system handles essential inventory tasks such as recording item details, updating stock information, and displaying stored data.

This project applies structured programming principles and file handling techniques to ensure accurate data storage and retrieval. It demonstrates the use of logical program flow, user input validation, and menu-driven operations, highlighting the importance of reliability and organization in business-oriented software systems.

Think Blink is an Arduino-based Simon Game developed using C++, designed to test and enhance memory, focus, and reaction skills. The game challenges players to observe and repeat an increasing sequence of lights and signals, promoting logical thinking and quick decision-making.

This project demonstrates the integration of hardware and software programming, combining microcontroller logic, input/output handling, and structured programming concepts. Through Think Blink, I applied C++ programming principles to create an interactive system that emphasizes accuracy, timing, and user engagement.

The PUP-Based Grades Calculator is a desktop application developed using Java and JavaFX, designed to compute and display student grades based on the grading system of the Polytechnic University of the Philippines (PUP). The application allows users to input academic scores and automatically calculate the corresponding final grade accurately and efficiently.

This project demonstrates the application of object-oriented programming concepts, user interface design, and event-driven programming. By using JavaFX, the system provides a user-friendly and interactive interface, highlighting the importance of accuracy, usability, and logical structure in academic software applications.
