Developer Competency Map
This map describes the core skill areas a developer should grow through to build real products with confidence. It is intentionally practical: fewer abstract categories, more topics that appear in daily work.
Use it to assess the current level, find gaps, and choose the next focus area for learning, mentoring, or practice.
Developer Levels
