Rachel Lougee developed user account creation event tracking for the mitodl/mit-learn repository, focusing on backend instrumentation to enhance analytics around user acquisition. She implemented event capture using Python, integrating PostHog through the Apisix middleware to log new account creations along with user details and the current URL. This approach enabled more granular funnel analysis and supported data-driven onboarding improvements. Her work maintained low overhead and clear commit traceability, aligning with product goals to quantify sign-ups and optimize acquisition paths. Over the month, Rachel demonstrated depth in API integration, backend development, and event tracking, delivering targeted analytics capabilities without introducing bugs.
