Dear sir,
I found your job post interesting and I think I'd be a great fit.
My qualifications and experience are great matches for this job.
I have 7 years of Node.js experience - have worked as a lead developer in various companies.
As a lead developer, I've built up the cost-effective, very productive backend APIs.
The performances were great, the clients were happy.
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.
