Developed a web application that enabled people to service their repaired products in an efficient, time saving manner. The application targeted on small scale service workstations to improve their workflow. Our idea was to create a platform between the public and the service vendors to interact wherein service vendors would quote their best offer for the service. The public had an option to choose the best suited service vendor.* Features include create, edit, and deletion of tickets* Automated e-mails and text messages using PHP* Implemented an auction system to get the best service* Location integration and anonymized communication used.
