First, go hire a professional resume editor, right now. It is literally their job to improve what you are describing. Don't cheap out either; this is an investment in your future.

Second, be honest. In your cover letter, tell your prospective employer that you feel like your resume seems boring. Tell them the exciting things you've worked on, and how it has helped you at work. Tell them how you're excited to learn new things and take on new projects, in addition to just getting better at doing the boring things. Express your interests, your passions, things about you that you think would make you a great co-worker.
