How far does a developer’s “I can do it” go?

The author argues that developer skill cannot be reduced to a simple yes-or-no label, based on Java study, an in-house website built alone, and work experience in Korea and Japan.

What was learned in school, what was built solo, what was handled in a team, and the scale and scope of a project are all different, so the same ‘Java experience’ can mean very different things.

Resumes should avoid vague claims like ‘Java capable’ or ‘worked on a large project’ and instead describe concrete responsibilities, contributions, and outcomes.

Details such as ERP, on-premises systems, IIS/ASP, Git conflicts, and code reviews help hiring teams judge real hands-on ability and collaboration skills.
