Hello Dear Employer
I just have checked the job post and I think I am a right candidate for your job.
I have extensive experience working with Nano Express(in the last security company), so I am sure that I can help you perfectly.
Please feel free to contact me anytime.
I am available 24/7 and I am able to have a test while interviewing.
Also I am ready to start working immediately and can provide full-time work for you.
Regards.
Samuel
