Core Tech: Deep-Dive Expertise in React.js, Next.js und TypeScript.
Performance & State: Optimierung von Ladezeiten und komplexem State-Management (Zustand, Redux, React Query).
Software-Qualität: Test-Driven Development (Jest, Cypress) und saubere Architektur-Patterns für langfristige Skalierbarkeit.
