Hello!
First, about your question, you can celebrate many things in Easter. If you're jew, it's the freedom frm slavery in Egypt. If you're christian, it's the ressurrection of Jesus. If you're pagan you can celebrate the Eostre goddess, and the fertility. If you're atheist you can just ignore the date...
Anyway, about your project, looks like there's already an official plugin for uploadcare. Did you check that? We could add the features you want to that plugin. It would be up to date wih uploadcare with no futher worries in the future. I'd like to develop a free prototype for you, based on your requirements.
I'm a Freelancer member since 2013 and part of Freelancer Preferred Program, thanks to the quality of the projects I've delivered and the high client ratings.
I work with a team of developers and designers in order to develop the projects more eficiently, with high quality standards.
I don't work with upfront payments. You can deposit the milestones in Freelancer and just realease it after I deliver each version.
Please get in touch so we can discuss your requirements and schedule a date for prototype testing. We usually take 7 days to develop a prototype.
Looking forward to hear from you.
Thanks!
