I've done a lot of PHP work dealing with reading and writing in Excel files. One of my recent job related to it is a french website to send bulk SMS online after uploading Excel Files. I've been able to read in the uploaded files, extract variables from them and compose messages to send to recipients.
I am proficient in Excel and have taken a course on it in college. I would love to get this task done for you and am confident I can complete the task well before the deadline.
I think I am the best candidate for this job because I have all the qualities that you are looking for. Experience is the golden factor in this project where you find in me at least 1.5+ years of working experiences over all the factors in your project.
