Basics
A full stack developer builds both halves of an application: the part people see and the part that makes it work. Here's what that involves.
Short answer
The frontend is everything running in the browser: layout, buttons, what happens when you click. Built with HTML, CSS and JavaScript, usually organised by a framework like React.
The backend is what the user doesn't see: it receives requests, applies business rules, reads and writes the database, handles authentication, sends a response. Written in Java or Python, structured by Spring Boot or Django. The database sits behind that, and SQL is how you talk to it, which is why it appears in almost every interview.
Given a feature, say letting users save a favourite, you design where it's stored, write the backend endpoint, build the interface, connect them, test and ship. Owning the whole path is what the title means.
In practice most developers lean one way, often spending sixty percent of their time on one side. The value of the label is optionality, not perfect symmetry.
It suits people who like building end to end and are comfortable with a wide surface area rather than deep specialisation early on.
Less so if you'd rather investigate questions than build applications (that's closer to data analytics), or if you strongly prefer visual design, which points toward frontend specialisation.
Demanding rather than conceptually hard. The difficulty is breadth and months of consistent practice, not any single idea being out of reach. Most people who fail run out of persistence rather than ability.
The set of technologies used together to build an application: a backend language, a framework, a database and a frontend framework. "Java full stack" usually means Java, Spring Boot, SQL and React.
Not inherently. Early on, breadth helps because it makes you eligible for more roles; later, deep specialisation often pays better. Both are viable careers.
Yes. Hiring weights demonstrated ability heavily: projects, code you can explain, interview performance. A degree helps at CV screening in some firms; it isn't a prerequisite.
