Your resume is actually fairly good, compared to many other resumes. However, it could still be stronger.
Most importantly, you could make your resume more accomplishment-oriented. You should take each job and ask yourself, "What are my 3-5 biggest accomplishments?” These should form the bullets of your resume.
As much as possible, quantify your accomplishments. How much money did you make for your company? How much time did you save your team? By how much did you improve customer retention? An estimation is okay here.
