A dedicated 'Technical Skills' section should be prominently featured, detailing your proficiencies. Your work experience section should then focus on specific projects, contributions, and the impact of your development work on critical systems. Ensure the resume is concise and technically oriented.

How do I write strong achievement bullets or a professional summary for this role?
Your professional summary should quickly convey your expertise in mainframe development and specific programming languages, focusing on maintaining and enhancing critical business systems.
