🏗 Architecture

• Frontend architecture — feature-based module structures with isolated API layers, adopted across multi-application codebases.
• Design systems — built and maintained reusable component libraries; extended shared systems across frontend teams.
• Data & caching — factory-based hook architectures for unified data fetching with session-persisted caching.
• Rendering & performance — SSR, dynamic routing, code-splitting, and virtualisation for large datasets.
• Build & quality — Vite pipelines with vendor splitting, pre-commit linting, and automated regression checks.
• Accessibility & standards — WCAG 2.2 AA conformance and Core Web Vitals for high-traffic public-sector services.
