Dear my client,
I am a senior php developer, I have worked on Upwork before and I started to work on Freelancer a little ago.
Over last 10 years, I have worked with many php projects.
I think you can believe my skills although you work with me for only 1 project.
I am a full time freelancer and have no any project now, so I can work plenty of time for you.
Contact me anytime you want.
Looking forward to hear from you soon.
Best Regards,
Ming Li
