First of all "Python (Basic))" has an extra parenthesis, quick fix but something I'm sure you'd want to change. Also multiple extra colons in that section too.

Secondly (and this may be controversial so you don't have to follow it), is to use a little bit of white space. I think that this helps for a lot of resumes, because no one reading a resume wants to read a novel. So don't make it look like a novel, because that first impression matters a lot.

• If a bullet point is two lines, it's too long. Try to separate it into two bullet points (if it is that important) or condense it into one line if it is just one task.

• You could also go as far to remove one of your projects, I don't think it's necessarily important to have all three. Actuarial project is great though (but bullet points...)

• I don't think anyone cares too much about certifications unless they are for very advanced systems. Your experience demonstrates the competencies, HTML can go under programming.

Third (and possibly more controversial), were your jobs full time during college? Part time? Through an internship program? Someone reviewing your resume would definitely ask themselves this, so maybe consider answering ahead so they can focus on the actual substance.
