Capabilities
Engineering capabilities
Frontend architecture
Structuring applications so teams can ship independently: module boundaries, micro-frontends, shared contracts and real-time data flow over WebSockets.
React and Next.js
Server and client component boundaries, rendering strategy, routing and data fetching for production applications.
TypeScript
Strict types at the boundaries between components, services and teams, so refactoring stays safe as a codebase grows.
Design systems
Design tokens, reusable component libraries and documentation that keep large interfaces consistent.
Performance
Measuring and improving loading, rendering and interaction speed against agreed budgets.
Accessibility
Semantic markup, keyboard support and WCAG-aligned engineering standards built into shared components.
Offline-first applications
Local-first data, background sync and conflict handling so applications keep working on unreliable networks.
