During August 2025, Dheeraj developed a UTM Parameter Persistence and Propagation feature for the ToolJet/ToolJet repository, focusing on preserving marketing attribution as users navigated the application. He designed a React component that captures UTM parameters from the URL, stores them in session storage, and appends them to internal links, including those leading to tooljet.ai. This approach ensured reliable analytics by maintaining attribution data across navigation paths. Dheeraj’s work demonstrated proficiency in frontend development, React, and UTM tracking, addressing a targeted persistence issue and validating end-to-end attribution, though the scope was limited to a single feature within the month.
