May 2026 (2026-05) monthly summary for drshahizan/HPDP. The work focused on enhancing performance benchmarking capabilities, expanding project documentation and architecture visuals, and aligning dependencies for maintainability and onboarding. No explicit bug fixes were reported; improvements target reliability, observability, and collaboration across the project.

June 2025 performance summary for Dr-Khatib/OOP-Section3-2425-2. Delivered two major features with strong OO design: an Online Shopping Cart System with User Roles and a School System Simulation Demo, both implemented in Java and designed for maintainability and future extension. The online cart enables customers to browse, add to cart, and checkout, while administrators manage product stock and view customer orders; the school system demo demonstrates inheritance, polymorphism, aggregation, and composition through a model involving Person, Student, Teacher, Course, and Classroom. These efforts establish reusable, well-structured code and meaningful educational demonstrations, setting the stage for scalable feature expansion and better maintainability. Major bugs fixed: none reported in this period. Overall impact: delivers end-to-end shopping workflow capabilities and a robust OO demonstration, enhancing potential business value and learning outcomes. Technologies/skills demonstrated: Java, object-oriented programming (inheritance, polymorphism, aggregation, composition), clear class responsibilities (Users, Products, Carts, Orders, Person/Student/Teacher/Course/Classroom), modular design, and documentation.

May 2025: Implemented a functional Share Store System Prototype in Java for Dr-Khatib/OOP-Section3-2425-2, establishing core entities (Members, Items, SpaceLots, Stores) and end-to-end workflows (assigning lots to members and storing items). Performed a small refactor to simplify string formatting for related methods. No major defects closed this month. The work lays the foundation for ownership tracking, inventory management, and reporting, and demonstrates solid OO design, refactoring discipline, and effective use of version control.

April 2025 delivered Lab Exercise 3: Array Manipulation Utilities and Student Class within the Dr-Khatib/OOP-Section3-2425-2 repo. Implemented a Java program that exercises array operations (finding the highest score and summing marks) and introduced a basic Student class to demonstrate array-based data handling. The implementation translates the lab requirements into a cohesive, testable module that can be reused for future labs and student practice. No major bugs were reported for this work this month; no bug fixes required in this area. Overall impact includes improved hands-on proficiency with arrays and OOP, with tangible business value in terms of a maintainable, ready-to-review module that supports course progression and assessment readiness.
