I build backend APIs that are tested, secure and easy for the next developer to pick up.

ShopHub

A backend API for an online store: catalog, search, cart, coupons, checkout, orders and reviews. I built it to practise the parts of a real system that are easy to get wrong.

• 35 Pest feature tests: auth, cart limits, checkout, coupons and order access. Writing them caught a bug that blocked every login.
• Safe checkout: one database transaction, plus conditional updates, so two buyers can't both get the last item, and a failed checkout rolls back completely.
• Security: Sanctum tokens, rate-limited login, strong passwords, and Policies so users only see their own orders.
• Documented: the README covers setup, routes, design decisions and how to run the tests.

• Laravel 13
• PHP 8.4
• Sanctum
• MySQL
• Pest

// Check stock and decrement it in ONE query,
// so two buyers can't both take the last item.
$affected = Product::where('id', $product->id)
    ->where('stock', '>=', $quantity)
    ->decrement('stock', $quantity);

if (! $affected) {
    // Throwing here rolls back the whole order.
    throw new InsufficientStockException(...);
