Dear sir,
Nice to meet you.
I found your job posting and I think I'd be a great fit.
I'm a qualified php engineer and I've worked as a senior engineer for a wide array of companies.
I can grasp the existing codebase shortly and can get started to modify the source code.
I'm very adaptable and can be flexible to any timezone.
I am ethical, treat team members fairly, and have two ears open for criticism as well as compliments.
Based on good past experiences, I can offer rapid turnaround, dedicated commitment and you would benefit if I am hired.
Looking forward to connecting to discuss.
Best Regards.Xu.
