Read the job description twice — once for context, once to highlight hard skills, soft skills, tools, and repeated phrases. Build a keyword list, match each keyword to a bullet point in your experience with numbers where possible, rewrite your summary to reflect the top requirements, reorder your skills section to lead with JD-relevant terms, adjust your bullet language to match the posting, align your job title with industry-standard terms if needed, and proofread so it still reads naturally to a human.
