Success Stories

Single Dealer Platform - Technology Migration to HTML5


Our client, a major European investment bank had a large, complex, market leading single dealer platform with a user interface that had been developed in Microsoft Silverlight. As Silverlight was approaching its end of life, they needed the user interface to be rebuilt as a modern HTML5 application.


Given the specialist skills required, the client had made the decision to outsource the development of the new HTML5 user interface. Baker Technology had a track record of successfully delivering projects to migrate single dealer platforms from Silverlight to HTML5 and so were selected for the project.


The Requirements

The existing platform was extremely feature rich, its functionality included FX cash, FX options and money market trading, limit and algorithmic orders as well as additional features such as position reporting.


The requirement was to produce a like for like replacement for the existing user interface maintaining the current user experience.


The bank was also in the process of deploying a new proprietary UI framework which we needed to integrate with and were replacing their middle tier real time pricing and trading services to optimise the performance for an HTML5 client.


The Solution

Baker Technology put together a team of ten specialist UI developers and testers at our City of London offices. We also provisioned an optimised build and test environment on our own infrastructure to allow for a rapid development cycle.


We built a simulator for the new pricing and trading services so that we could build and test against an agreed API whilst the client was completing the development of the real thing.


Using our technical and domain experience from previous migration projects we performed detailed analysis of the applications functionality, reverse engineered complex business logic from the existing code and rebuilt it in TypeScript/JavaScript and CSS hosted in angular.


The Approach

We ran the project using our lightweight agile methodology consisting of daily stand-ups, regular on-site show & tell presentations, transparent reporting and frequent releases.


We worked closely with many different client teams to integrate with both their new UI framework and back end services and also to coordinate testing.

The Outcome

At the end of the project we ran comprehensive knowledge transfer sessions for the client’s development teams to transition the development and maintenance of the new user interface to internal resources.


The HTML5 user interface successfully went live enabling the previous Silverlight one to be decommissioned. The client continues to maintain and enhance the new platform adding significant new features.
