React
Modern component-driven UI architecture, state management strategies, custom hooks, and performance optimization techniques.
1 / Component-Driven Development
React is the frontend framework I have used most extensively. Across CheckMate, Conclave, Foundry, Trajectory, Phoenix, and StudyLink, it has been the consistent UI layer that I build on.
2 / State Management Lessons
The most important React lesson I learned was about state architecture. Early on, I over-relied on deeply nested React Context providers for global state, which caused unnecessary re-renders across distant component trees. Working on Conclave's real-time multi-agent chat interface — where WebSocket messages arrived at high frequency — forced me to adopt Zustand for global state management. Zustand's selector-based subscriptions meant only components that cared about specific state slices re-rendered, which eliminated the performance problems Context created under high-frequency updates.
3 / Custom Hooks
Custom hooks became the cleanest pattern for encapsulating complex logic. In CheckMate, hooks managed the WebAssembly engine lifecycle — initializing the Stockfish binary, posting UCI commands to Web Workers, and parsing evaluation results back into React state. In Trajectory, hooks encapsulated API fetching, authentication token management, and form state. The pattern kept components focused on rendering while hooks handled the messy operational details.
4 / Performance
React.memo and useCallback were necessary in specific high-frequency rendering contexts — particularly in Conclave's streaming chat interface and CheckMate's real-time board evaluation overlay. But I learned not to apply them everywhere preemptively. Premature memoization adds code complexity without measurable benefit in components that re-render infrequently. The engineering judgment is profiling first, optimizing second.
