API Versioning Strategy: Backward Compatibility and Deprecation
How to evolve APIs safely with additive changes, contract testing, deprecation policy, and migration windows.
I was born in Ankara and have been a software engineer for about six years — mostly on the backend side. I care about code, music, and nature. Here I share notes, technical writing, and occasional reflections.
