Juha Pentikäinen contributed to the Slowers-Team/Slowers-App repository by building two core backend features focused on reliability and scheduling. He introduced a deterministic dependency lockfile using package-lock.json and implemented Sprint 2 release tagging, which improved build reproducibility and deployment traceability across CI/CD and local environments. In Go, he developed a time-based flower visibility scheduling system, adding the UpdateVisibilityByTime function and comprehensive unit tests to ensure robust type safety and correct timer behavior. His work emphasized backend development, dependency management, and database testing, delivering stable, production-ready workflows with clean commit history and thorough test coverage over a two-month period.

In 2025-03, delivered time-based visibility scheduling for flowers in Slowers-App and strengthened code quality with targeted fixes and tests. Key feature introduced: UpdateVisibilityByTime to mark flowers visible up to a specified timestamp, supported by unit tests and fixes for added_time handling and typing. Implemented critical bug fixes (int64-related issue, incorrect visibility state) and added tests covering visibility updates and timer behavior when toggling to visible. The work establishes a reliable, automated visibility schedule with robust type safety and test coverage, ready for production use in scheduling workflows.
