Back-end development
Back-end development is building the server side of a website: databases, APIs, logins, payments, and the business logic users do not see.
Example
When a student enrols, the back end saves their details, records the payment, and sends a confirmation email.
Why it matters
A solid back end keeps data safe and lets a website grow into a real product with accounts, orders, and automation.
