Frontend Application Architecture
Organize page state, navigation, rendering, and locale behavior without losing the HTML baseline.
Backend and API Systems
Shape read and write endpoints for growing collections and unreliable networks.
Data Persistence
Model records, preserve invariants under concurrent writes, and change schemas safely.
Media and Live Updates
Accept files, serve useful image sizes, and deliver ordered changes to active pages.
Offline and Device Capabilities
Cache a useful shell, keep local drafts, and reconcile changes after reconnecting.
Deployment and Scale
Configure releases, gate changes, share state, and prove recovery from data loss.
Content Discovery and Structure
Give public pages stable identities, navigable paths, and machine-readable meaning.
Identity and Application Security
Protect account access, recovery, federated callbacks, and server-side outbound requests.
Integration and Verification
Keep external events, API changes, browser journeys, and performance measurements honest.
Inclusive Interface Engineering
Design named controls, predictable focus, recoverable forms, and layouts that survive zoom and motion preferences.
