Projects delivered/Achievements

- Successful delivery of multiple strategic AWS hosted and Mobile (IOS/Android) applications that has driven cost savings and increased productivity of upto 1000%

Summary of each application:

• MetroApps Core: Custom developed single sign solution to manage user access across all our applications.
• Inform: Web/IOS based application that automates workflows and completely replaces the need for paper-based forms. Since project inception users have created over 3 million+ forms, delivering enormous cost savings in paper usage, printer and fax maintenance overheads.
• Ontrack: Network disruption management tool that allows Train Controllers to coordinate unplanned disruption and see performance impacts in real time. Information is pushed out to all staff out in the field so that they are better informed to assist passengers through the disruption.
• Metro Go: Application that allow Train Drivers to track their current performance in relation to the Planned Timetable in real time by utilising GPS coordinates. Additional features including looking up roster slips and submit medical assessments.
• Metro Connect: Custom chat application, allowing group discussions and broadcasting of active issues on the train network. Supports chat style messaging, image/video attachments and push notification.
• Metro Access: Planned disruption management portal. Third party contractors who require access to train tracks will require to submit their applications via this portal. All applications will then be assessed by Metro Staff via the portal which they then can plan for line closures.
• Paper Lite: Web/IOS based Document Management System that allows staff to share and access content on the go. Content can be training videos, word documents, pictures etc. Paper Lite has built in verbose security controls to restrict who can and can’t access the material.
• Fault Finder: Train diagnostic tool used by Train Drivers to assist in troubleshooting train related issues.
• Over Time app: Application that allows Train Drivers to submit overtime hours.
• Work On Track: GIS Map based application (Google maps/ NearMaps) that allows track workers to access hazard information whilst working on the train tracks. The solution was provided by a third-party vendor, my responsibility was technical oversight and that the project was delivered on time.
• XIBO digital displays: Combination of in-house development and off the shelf digital display platform that delivers content across the stations in various layouts.
