• JavaScript / TypeScript - strong fundamentals in JavaScript and TypeScript; comfortable with types, interfaces, generics, classes, OOP concepts, async/await, promises, closures, and the JavaScript event loop (call stack, microtasks, task queue, etc.).
• RxJS Reactive Programming - good understanding of Observables, Subjects, operators such as map, switchMap, mergeMap, catchError, tap, debounceTime, distinctUntilChanged, takeUntil, etc.; understands subscriptions, unsubscription, memory leaks, and handling asynchronous streams.

• Angular Performance - awareness of unnecessary change detection, efficient rendering of lists and large datasets, avoiding memory leaks, lazy loading, appropriate use of signals/RxJS, and optimizing components that handle frequently changing or streaming data.
• Team Collaboration - comfortable participating in code reviews, addressing review feedback, communicating blockers, discussing technical trade-offs, and pairing with other developers when needed.
