  rather than relying on generic AI content
• Skilled at adapting writing style to reflect the customer’s language, priorities, and evaluation
  criteria

  uncover customer priorities and create opportunities f or differentiation
• Detail-oriented, with a right-first-time mindset
• Resilient under pressure, with the ability to manage multiple deadline
