Worked on the GreenCityMVP21 repository, delivering comprehensive unit-test coverage for core filtering specifications in Java using JPA Criteria API and Mockito. Developed and documented two robust test suites for HabitFactSpecification and ShoppingListItemSpecification, addressing ID and content filtering, related entity joins, null content handling, and multi-criteria combinations. This approach strengthened the reliability of data-layer filtering logic for habit tracking and shopping list workflows, reducing the risk of regressions and enabling safer, faster feature iterations. Emphasized test-driven development and code quality, with clear test documentation to guide future maintenance and ensure consistent, high-confidence backend development practices throughout the project.
July 2025 (GreenCityMVP21) — Delivered extensive unit-test coverage for core filtering specifications to improve reliability and reduce risk of regressions. Implemented two comprehensive test suites: HabitFactSpecification and ShoppingListItemSpecification, covering ID/content filtering, related joins, null content handling, and multi-criteria combinations, with accompanying documentation. These efforts strengthen data-layer confidence for Habit tracking and Shopping List workflows, enabling faster, safer feature iterations and bug fixes. Demonstrated skills in test-driven development, code quality, and precise test documentation; commits include 0b4d4012315ded3300a290b7126bb318a8116740, a342fbd6f1ac02eaad1e40f86bc112b240adedaa, 81c3f819939a26da2a1a7e7e1bdce43466f1af44.
