Overall, too breezy and conversational. Objective should be more like "To become a Python or C software developer in [field of interest or company]." There's a lot of "I'm personable and a hard worker" fluff. They'll tell if you're a social fit from the interview, not the resume, and work ethic should be demonstrated by your experience and education. (If a person says they're smart, they're immediately doubted. They should show it.) Experience section could include much more detail and should tie-in with Expertise. Take the first entry. "Performed major system upgrade," doing what? Setup 30 servers, migrated from Windows to Linux, something else? "Developed software tools," which did..? What languages did the projects use (should support Expertise)? “large sets of data” how large? What kind of data? Mentoring a new hire should also be much more prominent. Bullet points should start with the most impressive bits first. Receiving a fellowship should be a part of Education, not Work Experience. Tightening is possible throughout: “Worked part-time through college to maintain financial independence.” Those are my random critiques. Hope they help.
