Developed a UTM Parameter Persistence and Propagation feature for the ToolJet/ToolJet repository, focusing on maintaining marketing attribution as users navigated the application and transitioned to tooljet.ai. The solution involved building a React component that captured UTM parameters from the URL, stored them in session storage, and appended them to all relevant internal links. This approach ensured reliable forwarding of attribution data for analytics purposes. The work demonstrated proficiency in frontend development, React, and UTM tracking, with careful attention to browser storage and cross-domain link handling. No bugs were reported or fixed during this period, reflecting a focused feature delivery.
