Engineering resumes are screened for what you built or owned: the product surface, the failure mode you fixed, and the scope you can defend in an interview.
Open with a title that matches the posting, then the most recent role. First bullets should name a system, your part in it, and an outcome you can explain without inventing metrics.
Languages and frameworks belong where a role used them. A skills block that the jobs do not support is the first thing a hiring manager probes.
No. List languages and tools you used in a real role. Interviewers ask about the first unfamiliar name on the page.
No. It is the evidence pattern. You write it in the builder from your own history. cvharbor does not invent employers.
