During July 2025, Amm Cap worked on the DefiLlama/defillama-app repository, focusing on frontend development with React and TypeScript. Amm addressed a targeted mobile UI issue by updating the event handler responsible for toggling dark mode from the settings menu, ensuring mobile users could reliably switch themes as on desktop and web. This fix reduced user friction and improved consistency across platforms. The solution was delivered through a disciplined, single-purpose commit, validated by code review, and referenced to the relevant issue. While the work was limited in scope, it demonstrated careful debugging and contributed to product stability and release readiness.
