The Challenge
Cross-border maritime trading partners in East Asia and Europe required instant access to verified commodity specs, shipping manifests, and port clearance records without experiencing database downtime or slow regional latency.
Our Approach
Designed a commanding industrial maritime aesthetic with deep navy blue, steel silver accent, and structured technical data tables.
Engineered a Next.js 15 App Router architecture with Prisma 5 ORM, Neon PostgreSQL serverless database, and Upstash Redis rate limiting.
Built a fault-tolerant offline fallback layer (`catalog-data.js`) ensuring public catalog availability even during database maintenance.
Key Capabilities
Import/Export Commodity Catalog
Structured directory for industrial raw materials, bulk agricultural goods, and freight specs.
Zero-Downtime Static Fallback Layer
Public catalog reads automatically failover to static dataset if database connection drops.
TOTP 2FA Admin Management CMS
Mandatory 2FA authentication for managing product catalogs, quote requests, and customer inquiries.
Cloudflare R2 Document Vault
Secure PDF export for shipping certificates, bill of lading documentation, and port declarations.
