Worked on the Polkadot Staking Dashboard, focusing on front end performance and stability improvements over a two-month period. Delivered targeted optimizations to chart rendering, data formatting, and validator filtering, resulting in faster navigation and reduced CPU usage for large validator sets. Refactored key React hooks, such as useValidatorFilters, to leverage stable callbacks and memoization, ensuring efficient state management and consistent UI behavior. Collaborated across teams through co-authored commits and thorough code reviews. The work, implemented in TypeScript and JavaScript, enhanced maintainability and responsiveness, particularly for workflows involving era graphs, pool searches, and nomination status categorization.

Mar 1, 2026March 2026: Polkadot Staking Dashboard delivered a focused performance and stability initiative across the UI. The work centered on speeding up charts and filters, stabilizing data flows, and reducing re-renders to provide a more responsive experience for validators and nominators. Key optimizations targeted era/period graph calculations, data formatting, and efficient lookups, reinforced by memoization and stable UI state management. Result: faster navigation, more accurate era graphs and price data, and a lighter CPU/memory footprint for common workflows.
