How do you determine your level of mastery in your professional field?

Determining the level of mastery in a professional field is a subjective process, but you can rely on several criteria:

• Knowledge and skills: how deeply and broadly you understand the technologies and tools you work with.
• Experience in solving tasks: how many and what kind of projects you have implemented, how complex the tasks were.
• Independence: whether you can work without constant supervision, make decisions, and take responsibility for them.
• Ability to learn: how quickly and effectively you master new technologies and approaches.
• Contribution to the team: whether you help colleagues, share knowledge, participate in architecture discussions.

For example, a junior usually knows the basics, performs tasks under guidance, while a middle-level is more independent, can design solutions, and optimize code.

Honest self-assessment and feedback from colleagues will help more accurately determine the level.
