About Mannah Kallon

I’m a gameplay engineer at Riot Games focused on building player-facing systems, UI, and tools that support live game development at scale. My work sits at the intersection of engineering, design, and player experience—developing systems that are not only performant and reliable, but intuitive and expressive for players and creators alike. I regularly collaborate with designers, artists, and product stakeholders to ship features in fast, iterative release cycles. Alongside my professional work, I’m an indie developer working on Rave ReVolt, a multiplayer combat platformer. This experience has deepened my focus on moment-to-moment gameplay, feedback systems, and designing for clarity under pressure. Before transitioning into engineering, I worked in curriculum development and education. That background continues to shape how I think about usability, feedback, and building systems that help users understand and act with confidence. I’m particularly interested in advancing UI systems in games and building tools that empower teams to create better player experiences.
