Over three months, Sandiuk Petro contributed to koldovsky/1368-team-02 and UA-1382-Java-Fundamentals by building user-facing features and robust backend systems. He developed front-end enhancements such as a dynamic contributor section and a Coming Soon module using HTML, CSS, JavaScript, and HTMX, improving project visibility and interactivity. In the Java Fundamentals repository, he implemented a full cinema ticket booking system with seating, pricing, and income logic, alongside a suite of object-oriented models and collections utilities. Petro’s work emphasized maintainable code structure, refactoring, and scalable design, supporting both immediate user needs and long-term extensibility across multiple modules.

May 2025: Delivered a full cinema ticket booking system with seating management, pricing, income calculation, and a user interaction menu. Implemented a comprehensive Core Java OOP data modeling and collections suite across multiple homeworks, including domain models (people, employees, vehicles, animals) and advanced collections utilities. Completed a Project Structure Refactor to standardize directories and package declarations, improving maintainability and onboarding. No explicit major bugs fixed this month; bug fixes were addressed within feature work and refactors. Business value: enhanced user-facing ticketing capability, reusable domain models, and a cleaner, scalable codebase for future features. Technologies/skills demonstrated: Java, OOP, collections API, domain modeling, refactoring, and project structure standards.
