Lead Engineer

Responsibilities:

Cloudbridge (developed using Java, MySQL, YUI, jQuery, Perl, Struts2) is a 'trickle box' which helps clients to back-up their data on the cloud to their preferred cloud storage services like Amazon S3, Rackspace, etc. Data can also be mirrored to multiple services or stored in a RAID5 fashion (after compression and encryption). As one of the Lead Engineers, I was involved in:
Designing and implementing the file Upload, Download and Delete Servers processes (using Producer-Consumer pattern). The upload and download servers were designed to work in a multi-threaded fashion to upload/download multiple files to/from the cloud after file chunking, stream based compression (gzip, bzip2) and encryption.
Developing many of the pages in the web portal (using YUI, jQuery, AJAX) including the Dashboard (real-time summary of the upload/download/delete sizes) page, Data Progress Monitoring (upload/download) pages, System Performance Monitoring pages, Cloud Data - Browse and Search (List view and Windows-style File Explorer view) pages, etc.
