Those are excellent things to put on your resume.

Do not worry about the work being unpaid. When you break down your resume into sections, make these the sections, in order:

Technologies: (C#, VB, MSSQL, ASP, etc.)
Development Projects:
Employment History:
Education:

In that "Projects" section list your code work. Be brief, but take as much credit as you can. Be sure to put URLs for the software projects if they are available online,make sure they are active (no dead links). If they are accepting resumes in Word, make sure these URLs are hyperlinked.

The only reason I put the Technologies laundry list first is that chances are you will be going through an HR gatekeeper who is using the laundry list to qualify you.

If you know that your resume is going directly to the technical folks, put the projects on top.

Good luck, Razor!
