Wren contributed to the noQ-sweden/noq_backend_python and noQ-Frontend repositories by building and refining both backend APIs and frontend features over a two-month period. They developed a detailed Activity Details API that aggregates volunteer information, leveraging Django, Python, and the Ninja Framework to ensure strong typing and maintainable contracts through Pydantic schemas. Wren also introduced a mock data generator to support robust testing workflows. On the frontend, they used React and JSX to resolve branding and dashboard sorting issues, improving user experience. Their work emphasized maintainability, clarity, and reliability, with thoughtful refactoring and targeted bug fixes across both codebases.
