MBTA mTicket

A 6 month cross-platform (iOS and Android) mobile app project for Masabi, a specialist mTicketing company based near London Bridge. The MBTA mTicket application was launched in the Android and iPhone app markets in November 2012, and was a complete success grossing $1 million of sold tickets in the Boston Rail network for the first ten weeks of operation.

Developing the Front End User Experience

The project focused on building the User Interface for the application, this was done as a HTML5 /JavaScript UI due to the inherent advantages in being able to share code across different platforms. During development, we regularly tested against Android, iOS, BlackBerry, Symbian WebOS and Windows Mobile.

MBTA mTicket Payment Walkthrough

The process for purchasing tickets is straight forward, no complicated steps or black magic.

To purchase a round trip ticket to/from Boston the steps are:

1) Click ‘Buy Tickets’
2) Choose a ‘From’ and ‘To’ Station from the list.
3) Choose a ‘Round Trip’ ticket
4) Choose an existing card (the app stores a payment key after the first time).
5) Enter the Card CVV

6) Review your purchase
7) Press ‘Pay Now’
8) DONE!

mbta.workflow.new2

Once the transaction goes through, the ticket is loaded into the My Tickets section. You now have two round trips to Boston waiting for you.

These last few panels are a shot of your ticket. The rectangle at the top shows the current time, the time block moves back and forth, and the three blocks are multi-colored. The color scheme changes on a daily basis according to a scheme that the conductor knows. Once the ticket is used it changes into a grey scheme. The conductor when he approaches will generally glance at the screen, nod with a “thanks” and put a paper slip in the holder above your head. Done.

Markit Commission Manager

Commission Manager is a trade reconciliation tool enabling brokers and funds in the worlds largest financial institutions to settle their commission differences.

The Project

The project involved a standardized platform to aggregate and manage trade information, commission balances and vendor invoices and payments.

Functionality

Markit Commission Manager enables users to reconcile their trading commissions with multiple counterparties and then instruct those counterparties to pay for research and brokerage services – all from a single platform. This efficient workflow eases the administrative burden of managing multiple commission arrangements.

The functionality is centered around trade reconciliation, raising of invoices and managing balance differences.

  • Detailed reporting of balance, trade and invoice information
  • Efficient tools to manage and highlight trade breaks
  • Administrative configurations for new users, tolerance levels, and arrangements
  • Compliance tracking of interactions within the Commission Manager system

Business Partner Integration

In addition, it was necessary to provide systems integration with all broker-dealers that were involved in the project.

Comments on the Commission Manager platform

UserSofia Rossato – Head of Markit Research Manager at Markit

Markit Commission Manager is the latest addition to our Markit Research Manager range of services. Our objective is to enable investment firms to manage their entire research workflow – including sourcing research, tracking corporate access, voting on brokers and managing research commissions – from one single platform to bring greater efficiency and internal visibility to the whole process. Markit Commission Manager is the final piece in the jigsaw. We have partnered closely with BofA Merrill Lynch, Barclays Capital, Citi, Credit Suisse, Deutsche Bank, Goldman Sachs, J.P. Morgan and Morgan Stanley to ensure the platform meets the needs of the industry.

UserFrank Volino – Head of Global Commission Management Services at Citi

This platform is good news for buy-side and sell-side alike. It will allow the buy-side to use a standardised set of tools to manage their commission credits at multiple broker-dealers. We are very pleased to be part of this important industry initiative. This platform is in a strong position to become the industry standard.

Pepsi Project Refresh

A global-reach social media campaign for renown household brand. This project involved designing an interface for a competition mechanics application with some of the latest technologies such as RESTful AJAX, jQuery, jQT, Qunit, HTML5, GitHub, Ruby on Rails all delivered over Amazon’s E2 Cloud delivery network.

The Pepsi Project Refresh

Pepsi Project Refresh – Global Competition Campaign

The Pepsi Refresh Project is an international social-media campaign aimed principally at teenagers and young adults, Pepsi’s main consumer base.

The project involved working with other skilled interface developers to customize the GUI and enhance an existing competition-mechanics platform (supplied by Global Dawn, a London-based specialist software developer) to provide Pepsi with the ability to create and judge competition rounds using bespoke rules, giving users have the ability to upload content and rate other user’s content all using Pepsi’s familiar blue branding.

Rich User Interface Technology

The principal technology stack of the project was RESTful AJAX over Ruby on Rails, this meant a highly-responsive UI that required minimal refreshing of the browser’s window. The main frameworks used for this were jQuery and QUnit(for unit testing).

Compatibility requirements meant unit-testing across various browser platforms.

A distributed team across several geographical areas meant using a robust and well-known Source Control and Bug-tracking platforms, GitHub, the platform of choice for many open-source projects was used for this purpose. Jira, another excellent solution provided by Atlassian, was used mostly for bug-tracking and task management.

Amazon Cloud

Various Technologies used for the Project

In order to improve high-volume delivery across all international location, the project used Amazons EC2 CloudDelivery Network.

Global Release

At then end of the project, the platform was localised and released across various international site. Russia and Italy being the first two participants in the competition.

Russian Site: platform was localised and delivered across various International Sites.

User-Generated Content

The key to the low-maintenance requirements of the competition is that users generate their own content. They upload videos and images, and they get to vote on videos and images provided by other users. According to Global Dawn’s 1-9-90 competition technology, some users tend to provide the majority of traffic and content in a site, hence these users are rewarded with ‘points’ to spend across the site as they see fit.

Italian Site: Users upload their own content and vote on other people’s content.

Competition mechanics are designed by brand managers (Pepsi in this case), they choose different parameters such as the duration of the competition, number of stages etc.
