Designing Symfony APIs for Scale
At Check24 I work on backend systems that serve millions of monthly users. Symfony is not trendy on Twitter, but it is excellent for long-lived APIs when you care about structure, testability, and clear boundaries.
Before implementation, write the API specification: resources, error shapes, pagination, and versioning. Scrum teams move faster when frontend, QA, and backend share the same document.
As a software engineer, your job is not only code — it is reducing ambiguity for everyone who integrates with your service.
