Reddit Achievements
As a senior software developer at Reddit, I led the development and successful launch of the Reddit Achievements and Streaks feature. This significant gamification initiative directly impacted Reddit's vast user base of over 30 million daily active users (DAU). My responsibilities encompassed the end-to-end development lifecycle, from initial conceptualization and technical design to implementation and post-launch iteration. By introducing a system of digital rewards for user engagement and consistent participation, the Achievements and Streaks feature demonstrably drove increased user activity across the platform.
