Mar 1, 2025Month: 2025-03 Key features delivered - CI Branch Handling for Linting and Tests: reworked the GitHub Actions CI to explicitly use the current branch name in checkout references and reusable workflows, ensuring linting and tests run against the correct branch and PR validation is deterministic. Major bugs fixed - Corrected lint/test execution against the active branch by passing the branch name to checkout steps; fixed tests that previously ran on the wrong branch. - Commits implementing the fix: 531508089a9901b164279dccfe1b24a88e2d9219; 775f441f0c4bdcd6b3ddcc9862482e8894f04d00; 26e18654fefd6dd92906a6ec6a2fce8ec0d542bf (messages: "Fix tests using wrong branch"; "Fix tests using wrong branch"; "Pass branch to checkout to lint/test steps"). Overall impact and accomplishments - Significantly improved PR validation reliability, reduced flaky CI failures, and accelerated feedback cycles for code changes. - Strengthened branch-context preservation across CI for linting and testing, reducing merge-blockers and increasing developer velocity. Technologies/skills demonstrated - GitHub Actions, reusable workflows, branch management in CI, test/lint pipeline debugging, and end-to-end CI reliability improvements.

Dec 1, 2024December 2024: Strengthened data integrity in time-tracking by preventing edits to committed worktimes (Ordertimes). Implemented a guard that blocks updates to finalized entries, ensuring only uncommitted worktimes can be changed via the existing update path. This reduces data drift, improves auditability, and aligns with business rules around finalized records. The change was implemented in puzzle/puzzletime with a focused code guard and minimal surface area.

Oct 1, 2024In October 2024, delivered a targeted reporting enhancement for puzzle/puzzletime to improve visibility of orders in closed-order reports. The reports controller was updated to conditionally apply a without_hours parameter when a closed parameter is present, and report generation logic was adjusted to honor this setting. This enables a more flexible, business-friendly view of closed orders without hours, reducing manual filtering and enabling faster decision-making.
