Khan Enterprise

A storefront and operations platform for Khan Enterprise, a fire safety equipment supplier based in Khulna, Bangladesh, serving Khulna, Jashore, Satkhira, Bagerhat, Narail and Mongla.

A searchable product catalogue across six categories — fire extinguishers, refilling and chemicals, alarm and detection, hose and hydrant, blankets and suppression, and PPE and signage — with BDT pricing, per-unit measures and live stock indicators. Rather than a checkout, the site uses an enquiry cart: customers add items and submit a quote request with delivery address and requirement details, matching how industrial supply is actually transacted, with call and email paths alongside. Behind it sits an operations layer for inventory, maintenance scheduling and compliance records covering the recurring servicing side of the business — refilling, pressure testing and annual maintenance contracts whose records must be ready for inspection.

A Next.js App Router application in TypeScript with Drizzle ORM providing type-safe access to PostgreSQL on Supabase, Zod and React Hook Form validating input, Zustand holding client state, and shadcn/ui with Tailwind for the interface. Authentication is custom JWT-based with dual roles, separating the customer storefront from the administrative area.

Localisation is structural rather than cosmetic: BDT currency, Bangladeshi address and phone formats, and regional delivery zones are modelled directly.
