Hasina International
International import/export, shipping & Chattogram port logistics portal.
The Brief
An enterprise import/export and maritime trading portal engineered for Hasina International in Chattogram, Bangladesh, featuring commodity catalog indexing, Cloudflare R2 document storage, NextAuth TOTP 2FA security, and zero-downtime static fallback query architecture.
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."
Architecture & Execution
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.
Measured
