Background
Mastercard is the world’s second-largest payment processing corporation, operating secure networks and partnerships that make transactions safe, simple, and smart. Their innovative solutions help everyone realise their greatest potential.
La Fosse has built a long-standing partnership with Mastercard, supporting their technology and engineering teams across multiple strategic initiatives. What began as a single project engagement has grown into an ongoing relationship, with La Fosse providing talent solutions that span engineering delivery, fraud prevention, and emerging talent development.
The Challenge
Following Mastercard’s acquisition of Vocalink, a business supporting member banks to manage transactions with their customers, they faced a significant technical challenge: migrating their Client Management Services layer from the acquired company’s infrastructure to Mastercard’s in-house Vocalink Technology Stack. This required specialist engineering capability to assess, test, and maintain a complex code base while ensuring continuity of service.
As the partnership developed, Mastercard needed further support to enhance their customer onboarding processes, strengthen fraud prevention capabilities, and migrate data points to a new platform. They also sought to build sustainable internal talent pipelines that would reduce costs and retain intellectual property within the business.
The solution
La Fosse deployed an engineering team encompassing analysts, developers, and quality assurance practitioners to manage the code base migration. Operating a flexible roll on/roll off model, the team of eight ensured the right specialists were available at each stage of the project.
For the fraud prevention and customer onboarding initiative, La Fosse provided five engineering consultants who hit the ground running. The team troubleshot all environments, upgraded and patched systems, and redeveloped the platform to meet enhanced fraud prevention requirements. Following launch, they seamlessly migrated existing customers onto the new platform.
To support Mastercard’s longer-term talent strategy, La Fosse introduced a junior DevOps consultant from the La Fosse Academy to join the Financial Crime Team, creating a pathway for homegrown talent development.
The results
The partnership has delivered tangible outcomes across all three engagements. The code migration was completed successfully with correctly skilled engineers deployed at each phase. The fraud prevention platform was launched on schedule, with existing customers migrated smoothly and comprehensive documentation handed over to permanent team members.
The Academy placement provided the Financial Crime Team with increased bandwidth while enabling Mastercard to establish an in-house talent pipeline. This approach saved money, retained intellectual property, and demonstrated how La Fosse can support clients from delivery through to capability building.
This ongoing relationship demonstrates La Fosse’s ability to grow alongside clients, adapting our services to meet evolving needs while maintaining the technical expertise and delivery focus that built the partnership in the first place.
