Describe the tasks and functions you were able to implement in previous projects

In previous projects, I have implemented various tasks and functions, such as:

• Developing REST APIs for handling user requests, including CRUD operations with the database.
• Automating data processing: parsing incoming files, validation, and saving to the database.
• Implementing business logic, such as calculating discounts and generating reports.
• Integrating with external services via APIs, including error handling and retries.
• Writing scripts for data migration and transformation.

For example, in one project, I wrote a function to process orders, which checked product availability, calculated the total cost with discounts, and saved the order to the database:

def process_order(order):
    if not check_stock(order.item_id, order.quantity):
        raise ValueError("Insufficient stock")
    total = calculate_price(order.item_id, order.quantity)
    order.total_price = apply_discount(total, order.customer_id)
    save_order(order)

These tasks helped me develop skills in data handling, application logic, and database interaction.
