Worked on the LimeSurvey/LimeSurvey repository to implement Survey Response Data Enrichment, extending the TransformerOutputSurveyResponses structure to include ipAddr and refUrl fields. This enhancement enables richer analytics and downstream data processing by capturing additional context from survey responses. The approach focused on maintaining backward compatibility by marking the new fields as optional and updating serialization logic to avoid disruptions to existing pipelines. Documentation was updated to guide analytics teams in integrating the enriched data. The work was carried out using PHP, with an emphasis on backend and API development, reflecting a targeted and maintainable addition to the project’s data handling capabilities.
