Client overview

A UK fintech firm builds platforms for pension providers. Its flagship system delivers scalable capability and handles millions of transactions yearly, aligned with HMRC and FCA reporting standards, to support compliant, efficient pension administration.

An 80-person team supports over 30 UK pension providers, from major banks to specialists, powering savings for 250,000 people. About half the staff come from pensions roles, delivering technology and consulting expertise on engagements.

Challenges

This fintech platform's outdated architecture, strict integration needs, and system limitations affected release quality and reliability.

Frontend limitations

The legacy front end lacked modular structure and maintainability, slowing delivery and limiting alignment with backend modernization efforts.

Integration complexity

Connecting the platform to existing systems required extensive coordination to support financial workflows like SIPP without breaking legacy logic.

Quality assurance gaps

Insufficient test coverage across the front end and APIs made it harder to validate stability and meet enterprise-grade reliability requirements.

Solution

We modernized the platform’s architecture, development process, and front-end system to enable scalable delivery and stronger quality control in a highly regulated domain.

Legacy architecture & data migration

Migrated terabytes of pension data using secure cloud migration strategies while modernizing legacy components to create a scalable foundation.

Component-driven frontend

Modernized the frontend with modular, reusable components to reduce duplication, improve maintainability, and accelerate delivery across distributed teams.

Expanded automated testing

Implemented automated testing across UI and API layers to increase release reliability, speed up regression cycles, and meet enterprise-grade quality expectations.

CI/CD pipeline modernization

Set up CI/CD workflows with integrated test automation to reduce manual effort, shorten release cycles, and ensure consistent, predictable deployments.

Business impact

The platform transformation led to significant gains in delivery speed, system stability, and test coverage, which impacted both internal teams and institutional clients.

Improved test reliability

Expanding automated test coverage helped standardize quality checks and supported consistent delivery across UI and backend components.

Modernized user interface

The new front end enabled faster iteration, reduced UI debt, and supported broader compatibility across screen sizes and accessibility requirements.

Faster release cycles

CI/CD integration helped reduce deployment bottlenecks, speed up delivery timelines, and improve responsiveness to change requests.
