David May-miller

Worked on the communitiesuk/submit-social-housing-lettings-and-sales-data repository, focusing on backend enhancements and test reliability. Delivered a data collection scheduling update by extending the 2024 collection end date, improving data completeness and supporting accurate reporting. Addressed security vulnerabilities through careful dependency management, pinning Nokogiri and Thor gem versions. Enhanced the test suite by implementing dynamic collection year handling in RSpec, ensuring tests adapt to year-end transitions and reducing brittleness. Refactored test data and logic for maintainability, and improved error handling for organization merges by restoring direct RecordInvalid exceptions. Utilized Ruby, SQL, and Ruby on Rails throughout the development process.

2025-08 monthly summary: Focused on stabilizing year-end transitions in the test suite and strengthening error handling for organization merges in the submit-social-housing-lettings-and-sales-data repo. Implemented dynamic collection year handling to adapt tests to the closing of the 2023 financial year and upcoming collection years, and reverted a previous merge-failure change to raise RecordInvalid directly, improving reliability and error visibility. Result: more predictable QA cycles, reduced test brittleness during year-end transitions, and clearer data integrity signals for merges. Demonstrated competencies in test data management, refactoring, and robust exception handling.
