Hello, sir.
I’ve just read your job description and I know I'm the ideal one for you.
Just talk to me. I do not like a tirade but prove myself by act.
As a full-stack developer, I did this kind of work before and my client was satisfied with my work.
If you want, I can provide you with my work or you can check my skills through my portfolio.
Looking forward to hearing from you soon.
Thanks & Regards
