Backend developer: the logic and data behind every app
The roleWhat a backend developer does
A backend developer, also called a back end developer or backend engineer, builds the server side of applications: APIs, business logic, databases, authentication and integrations with other services. Users never see this code, but every click depends on it.
A typical task: a mobile app needs order history. The developer designs the database tables, builds a REST endpoint with pagination, adds caching for speed, writes tests and documents the API for the mobile team.
Backend development can use many languages: Java, Python, Node.js, Go, C#, PHP or Ruby.
Backend developers work in almost every type of company: banks, online stores, streaming services, SaaS products and startups. Some focus on business logic and APIs, others on data, integrations with payment or delivery providers, or high-load systems that serve millions of users.

| Skill | What it is used for every day |
|---|---|
| A server language | Java, Python, Node.js, Go or C# |
| APIs: REST, GraphQL | Connecting front ends and services |
| Databases: SQL, NoSQL | Storing and querying data |
| Caching and queues | Speed and reliability |
| Security | Authentication and safe data |
| Cloud and Docker | Deployment |
Getting startedHow to become a backend developer
No degree is required, though many backend engineers have one.
A simple backend developer roadmap: one language, HTTP and REST, SQL, a framework, testing, Docker and cloud basics. Build two or three APIs with databases and authentication.
Choose one language and go deep instead of jumping between many. Learn how HTTP works, how to design clear APIs, how databases use indexes and transactions and how to handle errors and logging. These fundamentals transfer to any language later.

GrowthBackend developer roadmap and career path
Common path: junior, mid-level and senior developer, then lead or architect.
Backend developer jobs, back end developer jobs and backend engineer jobs are among the most common in tech, and many are remote.
Senior backend developers design services, think about scaling and failure, and review designs of others. From there, the path leads to architect, staff engineer or engineering manager roles.
