Seed case study — illustrative, pending content-team sign-off and client approval before publication.
Challenge
A live trading and treasury platform had to move — across versions, and onto cloud infrastructure — without the desk feeling it. The risk in a programme like this is rarely the technology in isolation; it is the integration surface, the data migration and the operational handover.
Approach
Practitioners who had run these environments led the work. We de-risked the cutover the unglamorous way:
- Automation-led testing across the integration surface, so regressions surfaced early.
- Monitoring that tells the truth — observability built in before go-live, not after.
- An operating model that did not depend on heroics, with a clean handover to managed operations.
Outcome
A controlled cutover and a platform that kept running — evolving and defensible — while the bank’s team stayed focused on the business. The kind of result that earns the next programme.
