Hi,I am a Frontend developer with 5 years of experience.
I have worked on several similar projects before, and can deliver result in tight deadlines.
You can see an cronjob example of those projects in my portfolio here:

I am sure I can develop cron job in a short time.
If you award me the project I'd be very happy to discuss this further and get started for you as soon as possible.
Thanks!
Zhongbo.
