The resume lists mostly sysadmin and supporting tasks. Dev tasks (like "developed web-based email search" or "Shipped working code") are too vague. The layout (especially the "Knowledge and Skill" section) look like you're trying to pad things out to fill a page. If you do more admin stuff, maybe you are applying for the wrong jobs. If you are looking for software development jobs, be concrete. Give examples of projects you've built or contributed to: e.g. "Implemented significant features for in-house helpdesk ticketing system (Python/Javascript/HTML/CSS) supporting 35 users and over 2700 tickets/week." Enumerate the "working code" that you shipped.
