Backend development is more than writing endpoints for frontend

Backend development encompasses far more than writing API endpoints. A backend developer must master a broad set of skills including choosing appropriate programming languages and frameworks, working with relational and non-relational databases, designing APIs (REST, GraphQL, SOAP), managing servers and cloud hosting environments, testing and debugging, collaborating with teams, implementing messaging systems (Kafka, ActiveMQ), securing applications (JWT, SSL/TLS, bcrypt, logging), and applying caching strategies (Redis, Memcached, Varnish). Each area is introduced with key concepts, tool examples, and links to further learning resources.
