Lachlan Dow contributed to the Planning-Inspectorate/appeal-planning-decision repository by delivering eight features and resolving two bugs over five months, focusing on regulatory workflows and user experience. He implemented reusable email notification systems and enhanced form validation, using Node.js, TypeScript, and Express.js to ensure maintainable, testable code. Lachlan introduced environment-based feature flags and infrastructure-as-code practices for safer rollouts, and improved UI layouts for better information density. His work included middleware for robust date input handling and corrections to data routing, demonstrating attention to data integrity and release governance. The depth of his contributions reflects strong backend and full stack engineering skills.

September 2025 (Planning-Inspectorate/appeal-planning-decision): Focused on stabilizing core input handling and data routing. Delivered two critical bug fixes that reduce user friction and improve data integrity: Robust Date Input Validation and LPA Contact Email Data Corrections. Prepared for production with clear commit messages and traceability.

August 2025 — Key feature delivery and bug fixes in Planning-Inspectorate/appeal-planning-decision. Implemented Date Input Validation Enhancement via middleware to convert month names to numeric values, extended validation to accept numeric months and common month abbreviations, and propagated changes across multiple routes and components within the forms-web-app package. Result: improved user experience and data integrity across date fields. Notable work included addressing end-to-end date validation issue (A2-3980) with commit 58e532b53b8ac0130a4dcc6c6cf1ec45ead9d376.

June 2025: Delivered a focused UI improvement for the appeal decision workflow by widening the appeal page content column to two-thirds, improving readability and presentation of appeal details within the grid layout. This aligns with design standards and enhances reviewer efficiency. Change implemented in Planning-Inspectorate/appeal-planning-decision; associated fix commit cc36bf1f5d0fa44ab733a7cf2a8d194c3ddc1f30 addressing A2-2705.

May 2025: Delivered core Scoping Opinion functionality for LPA questionnaires (S20/S78) in Planning-Inspectorate/appeal-planning-decision, including a new scoping opinion question, document upload page, UI enhancements, and test alignment, all guarded by a feature flag. Implemented an environment-based rollout control for the feature via infrastructure-environments to enable per-environment enablement. Fixed essential bugs in the scoping opinion flow (boolean page title and routing) and performed test configuration cleanup (removing journey-file coverage) to reflect the updated scope. These changes support regulatory-aligned decision workflows with safer, auditable rollouts and improved release governance. Demonstrated skills in feature flagging, environment-specific configuration, test-driven development, and UI-backend integration.

April 2025: Implemented a cohesive email notification strategy across appeal flows using reusable templates and a NotifyService integration. Delivered four new notification features with associated tests, refactors, and template renames to improve maintainability and user communications. The work enhances compliance, reduces manual follow-ups, and stabilizes end-to-end submission notifications.
