Over five months, Andrés J. Arias developed a suite of educational and business applications in the elascano/ESPE2410-OOPSW1973 repository, including a restaurant ordering system, a bank interest rate calculator, and contact management tools. He applied Java and Python to implement object-oriented designs, leveraging design patterns such as Strategy, Abstract Factory, and Composite to ensure modularity and maintainability. His work integrated MongoDB for persistent data storage and featured GUI development with Java Swing. Arias emphasized code organization, refactoring, and documentation, producing reusable scaffolding and visual artifacts that improved onboarding, traceability, and long-term stability across multiple project domains.
In March 2025, delivered an end-to-end Bank Interest Rate Calculator in Java with a data model for interest rate data, a calculation controller, a GUI, and MongoDB persistence. This work provides a runnable financial calculation tool with persistent storage, improving accuracy, data integrity, and user experience. Complemented by project-focused documentation and visual artifacts to aid reviews and onboarding. No major bugs were reported for this period; all changes are fully traceable to specific commits.

Month: 2025-01 | Repo: elascano/ESPE2410-OOPSW1973. Delivered a robust multi-project foundation across Java and Python, enabling Galaxy app, Student DB app, and MongoDB-backed student interactions. Implemented scaffolding and refactor work to improve maintainability and onboarding, and introduced a main entry that initializes data structures and prints representations. Added a GUI-based Contact Management System with MongoDB persistence and data display, and established an OO design for drawing animals that supports polymorphic handling of birds and mammals. Launched foundational Python utilities (arithmetic, login, language model) with unit tests to improve reliability and reusability. These efforts lay the groundwork for scalable feature delivery, reliable persistence, and cross-language collaboration across the stack.

December 2024 monthly summary for elascano/ESPE2410-OOPSW1973. Focused on delivering core educational features, stabilizing project scaffolds, and implementing persistence for future tasks. Key features delivered include: (1) Reverse Engineering/Data Modeling Exercises (A-F) with diagrams, establishing A-F class models, a Main demo, and project configuration artifacts to facilitate learning and future reverse-engineering tasks; (2) Contact Book and Contacts Demo Projects (PrjContactBook, PrjContacts) demonstrating a Contact class, a Person class, and ArrayList-based storage for simple contact management demonstrations; (3) Ant Simulator Core Framework establishing the foundational model classes (Ant, Cell, Colony, Food, PheromoneDrop) and a main entry point to illustrate basic interactions; (4) Galaxy Data Management introducing a Galaxy model, a main menu-based application, and JSON-based save/load utilities for persisting galaxy information. Notable bug fix: corrected an incorrect folder deletion encountered during the reverse-engineering exercise workflow. Overall impact: delivered a cohesive, reusable educational stack across four domains, enabling faster onboarding, clearer demonstrations of OO design, and durable persistence patterns for future projects. Technologies/skills demonstrated: Java, object-oriented design, ArrayList usage, class diagram artifacts, and JSON-based persistence.

November 2024—Focused on building the backbone for course materials and core system prototypes in elascano/ESPE2410-OOPSW1973. Delivered structural scaffolding for Homework and Workshop content with directories, placeholder READMEs, and evidence artifacts to streamline material delivery and assessment. Implemented a Menu Item Ordering System prototype (initial MenuItem class and usage) to validate ordering workflows. Expanded the Chicken Farm Simulator prototype (Chicken model, farm simulation components) with a separate customer data persistence project to explore persistence patterns. Across these efforts, established reusable OO design patterns, modularization, and robust commit-based traceability across evidence and scaffolding work, enabling faster reviews and future integration.
