After completing my third year, I secured an internship at Unmesh Summer Internship Program 2014 by CESC Limited. In about 6 weeks, I developed the Bill Delivery Monitoring System. It is one of the most complex and real-time web applications that I have ever created. The system became immensely popular, and was instantly moved to production. I won the best intern award that summer.
Bill Delivery Monitoring System
Award winning web-application project to monitor the timely printing and delivery of electricity bills to consumers.
A web-application to monitor the timely printing and delivery of monthly electricity bills and notices (defaulter’s bills) to consumers.
- Three kinds of users – CESC Officials, Bill Printing Vendor, and Bill Delivery (Courier) Vendor – with different sets of use cases via common login.
- Granular monitoring of bill printing (three events) and bill delivery (three events) in sequence.
- Automated SMSs sent to consumers when their bills are calculated, and are out for delivery.
- For ease of interaction and reduce input mistakes, textboxes have not been used. The main process flow is merely a series of button clicks.
- Website is fully responsive and mobile friendly – first of its kind to be implemented for the company in 2014. Courier Partners have benefitted the most, as they can tap the buttons easily in their phones / tablets, while on the road, delivering bills.
- The application won the Best Project Award at Unmesh 2014 Summer Internship Program
- Whole back end implemented using JSP-Servlets and Java Classes.
- Designed SQL schema for high scalability and robustness.
- Designed an intuitive front-end for easy tracking of bill delivery, and associated miscellaneous reports.
- Automated SMSs are sent to hundreds of consumers using dedicated SMS gateway, which are triggered for certain events.
- System is live for over 2.5 years, with approx. 100,000 database hits per day from different users.
Login page only, as system is live, and access is restricted.
