WorldGuessr Mobile App Development

While working on WorldGuessr, a popular geography-based web game with millions of monthly users, I led the development of its mobile mode to ensure smooth, intuitive gameplay on phones and tablets. The original experience was heavily desktop-oriented — with features like keyboard-based panning and a wide layout — so I focused on creating a responsive interface that felt natural on smaller screens. This included touch-friendly controls, dynamic scaling of UI elements, and rethinking layout logic for menus, maps, and Street View embeds.

On the technical side, I worked primarily with Next.js, React, and Tailwind CSS, optimizing components for mobile rendering and adding conditional logic to adapt behaviors based on screen size and input type. I also collaborated with the rest of the dev team to implement viewport-based transitions and ensure consistent performance across browsers and devices. The end result was a polished mobile experience that significantly expanded the game’s reach, especially among casual users playing on the go.
