Developed a dedicated Demex Referrer Configuration Parameter for the Switcheo/demex-webapp-config repository, enabling dynamic referral tracking through a new JSON key-value pair. Focused on configuration management, the work replaced hard-coded toggles with a flexible approach that allows marketing teams to attribute referrals and experiment with growth strategies without requiring code changes. By enhancing configurability and traceability, the solution reduces deployment risks and supports future campaign adjustments. The implementation centered on updating configuration files and ensuring seamless integration with existing systems, demonstrating a methodical approach to managing application settings and supporting business objectives through robust configuration practices.
