Project Description

I need an experienced programmer with experience of large scaleable application design AND experience implementing Amazon Webservices expecially S3 using PHP.

Do not apply if you have less than 10 years experience of delivering software.

Key skills and technologies:

Technical design architecture



Amazon S3 storage


You will be required to deliver onto my webserver a system whereby a user can upload a file (of any size) and securely store it. This file must not be available to the public to find or view.

When an HTTP request is received, the file will need to be retrieved for download.

You must record the amount of data that has been downloaded so that a file can only be downloaded once.

Once downloaded the file needs to be removed from the temporary storage.

The person I will chose for the work will have a clever technical design whereby the storage capacity of the webserver and the S3 storage is being optimised and all URL's are being masked from the user.

Other functionality required will be:

Record amount of disk space used by a User

Delete User files from cloud

There will be some mySql database activity during each file transaction BUT most user related PHP object functionality will be supplied.

Using SWFUpload (Flash/Javascript visual upload) the file will be uploaded straight to the S3 storage whilst another process will store details in the Db.

If you do not have experience of SWFUpload but fulfill the rest of the project criteria, please apply.

All web pages will be pre-prepared for you and supplied as HTML & CSS.

Your job will be to focus on the file processing code and functionality ONLY.

I will require a brief Technical Design document from you that shows your intention for the build and that you understand all the key areas:

scaleability, storage space optimisation, web server load.

I have included a basic scrawled specification for your immediate assistance.

A more detailed functional spec with all details will be supplied.

I look forward to meeting you.
