— RESILIENCE & PROBLEM RESOLUTION

cloud_off The Network Fragility

Most recipe applications depend completely on external network connectivity and rate-limited third-party endpoints. When users hit cellular dead-zones or API quotas, standard apps freeze, leaving users without cooking guidance.

bolt Automated Circuit Breaker Fallback

Engineered with an offline-first circuit breaker: when live calls time out or return HTTP 429, the application instantly routes queries through a local embedded catalog of 60+ nutritionally indexed recipes, rendering results in under 10ms.

— SYSTEM ARCHITECTURE

Failover Circuit Breaker

Automatically detects API latency or rate limits, gracefully switching data retrieval to client-side catalogs with zero user friction.

Zero-Dependency Runtime

Ultra-lean vanilla JavaScript ES6+ architecture eliminating bloated bundles for sub-100ms cold boots across low-end mobile devices.

Local Storage Synchronization

Persists custom community recipes, favorites, and dietary exclusions securely in browser storage across sessions.

— KEY CAPABILITIES

— ENGINEERING CHALLENGES & RESOLUTIONS

timer Challenge: Third-Party API Quotas & Rate Limits

Frequent user searches quickly exhausted daily API quotas on public recipe endpoints.

Resolution: Implemented client-side response caching with expiration timestamps and automated fallback indexing to minimize redundant external API requests.

filter_alt Challenge: Multi-Constraint Ingredient Matching

Matching arbitrary multi-ingredient user queries against recipes with varying naming conventions and dietary filters.

Resolution: Constructed an efficient array-intersection matching algorithm that ranks matching recipes by highest ingredient overlap percentage.
