01Under the hood

One order, six systems — all built by me.

Follow a Mahalun Mart order from the storefront to the admin panel. Tap any stage to see what I built there.

Stage 01 of 06

Storefront

Customers browse the live catalogue on any phone. Fast, responsive pages that search engines can read.

  • HTML
  • CSS
  • JavaScript
  • Responsive frontend
  • SEO basics

// storefront.jsconst res = await fetch( '/api/products?cat=choc');render(await res.json());

Stage 02 of 06

Checkout

A custom checkout with Cash on Delivery and manual bKash / Nagad payment verification.

  • Payment integration
checkout.jsSimplified example
// checkout.jsawait post('/api/orders', { items: cart, payment: 'bkash', // or 'cod' trxId});

The Express backend validates every order, prices it, saves it and tells the rest of the system.

  • Node.js
  • Express
  • REST APIs

Database

SQLite keeps products, orders and an audit log of every edit made in the admin panel.

  • SQLite
  • Orders
  • Products
  • Audit log
orders.sqlSimplified example

Stage 05 of 06

Alerts

The moment an order lands, Telegram pings with one-tap Confirm / Cancel, and the customer gets a confirmation email.

  • Telegram Bot API
  • One-tap Confirm / Cancel
  • Order emails
telegram.jsSimplified example
// telegram.jsbot.sendMessage(chatId, 'New order received', { buttons: ['Confirm', 'Cancel']});mail(order.email, 'Received');

02Case study

Mahalun Mart — a full e-commerce platform built from scratch

Mahalun Mart is a live online store selling imported chocolates, skincare, ramen, and coffee across Bangladesh, backed by a Facebook page with 40,000+ followers. I built the entire platform: a Node.js/Express backend with SQLite, custom checkout supporting Cash on Delivery and manual bKash/Nagad payment verification, a full admin panel (product management, bulk import, order editing with audit log), guest order tracking, automated order-confirmation emails, a phone-verified product review system, and Telegram-based order notifications with one-tap confirm/cancel. I also handled full production deployment and troubleshooting — DNS, SSL, server-level debugging, and security hardening.
