Implemented web services using the django framework to act as a proxy for iOS native clients. The application fetches data from remote web services and filters out data for an iOS client based on filters specified by the admin. The services implement disk based caching to speed up response times to the iPhone client. The services use JSON to keep response size small. We configured and set up the server and the application.

Technologies:
OO Perl, PHP, Linux, Debian, SSH, Shell Scripting, jQuery, AJAX
Designed and implemented porting of a tool from PHP to OO Perl to find dead sites based on URLs and links uploaded by the user. The interface allows the users to upload a csv file with links and to optionally also enter extra URLs in a text area. The challenge was to process thousands of URLs in real time which was causing the existing module/script to timeout. We designed and implemented a solution using fake fork with Non-blocking system calls and Ajax that would allow the processing of all the URLs with real time notification to user's browsers with Perl backend and jQuery/Ajax for an UI notification.

Designed, implemented and fixed several processes and workflows on a Django Python based Job Portal. The application provides three levels of access and privileges for job seekers, employers and administrators respectively.
Employers are given an initial free trial period for searching resumes but once this expires they have to purchase subscription packages from the portal to continue resume search and posting of jobs which applicants can apply for.
Job seekers create/update resume on the site and apply for jobs posted by the employers. The Administrators can have different set of access privileges set to administer different activities in the portal.
The site also provides forums for discussions and Content Management System to facilitate administrator to create content for the portal.

Technologies:
OO Perl, PHP-Custom framework, HTML Template Engine, MS Sql Server 2005, jQuery
Designed and implemeted an admin interface on an existing system for managing all statistics and activities of users participating in any competition being organized by a particular client. A client here is an entity that is identified on the web via a unique URL. The admin has three types of users that can login - super admins, client admins and sales rep admins.
br>

Super admin has all the privileges such as managing all the users as well as other client information for any contest, while client admins have privilege only related to their own competition and users related to that competition. A sales rep admin has the least privilege and are able to just see the statistics flow.
br>

The application is able to get all the information retrieved for the admin users such as number of users involved in a particular competition, scores of an user, ability to change their personal information, comparison of different competitions statistics, searching of any particular user in all the contests, creating and deleting a new admin and assigning their roles for different competitions (only for super admin).

Designed and implemented features and enhancements on a popular Opensource Web app to manage Agile Scrum based projects. The scrum tools allow for creating and tracking user stories for a project. The application was built using the Django framework and we implemented REST API interfaces for other applications to interface with the system. Among features, we added the APIs for user project creation and management, user tasks and iterations management. The UI was enhanced using slick jQuery drag and drop interfaces and a basecamp style calendar was also implemented. Excel sheet based tasks can also be imported into the system and exported out of the system. The application allows users to generate reports and set up schedule for automatically generating them and sending emails. Both text and graphical reports can be generated.

STONE SIM is a software system designed and implemented as a dashboard application to get system status of different systems deployed inside the LAN(we are still testing its functionality over the internet). It basically uses different well known open source applications to provide the system logs and other statistics. Then IDS tries to analyze those logs and statistics to get a sense of the systems. It also features application monitoring in which we monitor application logs using rsyslog on client side and send the to server using tcp where they are analyzed accordingly. All this data is represented in form of charts. We can also generate reports based on these logs and system statistics in pdf, csv and xls formats.
The main functionality for the system as follows:
- Gather system statistics of different host machines.
- Store system statistics in a centralized place
- Analyze system statistics and Logs
- Gather application logs from client systems
- Analyze these application logs on the server side
- Notify users if something goes Wrong
- Generate reports based on these charts.

Designed and Implemented a django application/module to synchronize inventory data from Satchmo e-commerce store to Merchant OS and vice versa automatically. The system was implemented to handle auto updates on the inventory count as well every time an item is sold on the Satchmo store.
The system allowed for the admin to map all inventory items based on a 1-1 mapping in the two systems. Once the products are mapped in both Satchmo and MOS, the inventory is automatically updated on every purchase on the Satchmo store. We also implemented an extensive reporting module in the satchmo application where the admin can view total sales figures from both systems and analyze data.
