Share your experience of implementing a significant project you participated in.

In one of my projects, I participated in developing a web application for inventory management using PHP with the Laravel framework. The main task was to create a system that allowed tracking the receipt and expenditure of goods, as well as generating real-time reports.

During the implementation, I was responsible for:

• Designing the database and creating migrations.
• Implementing REST API for frontend interaction.
• Optimizing queries to improve performance.
• Implementing authentication and access control systems.

For example, to handle product receipt, I implemented a controller that checked product availability, updated the quantity, and recorded the transaction in a log:

public function receiveProduct(Request $request) {
    $product = Product::find($request->product_id);
    if (!$product) {
        return response()->json(['error' => 'Product not found'], 404);
    }
    $product->quantity += $request->amount;
    $product->save();

    InventoryLog::create([
        'product_id' => $product->id,
        'change' => $request->amount,
        'type' => 'receive'
    ]);

    return response()->json(['success' => true]);
}

This project helped me gain a deeper understanding of MVC architecture, working with databases, and REST API development in PHP.
