Modern channels beside a core that stays up
The core cannot be switched off, the regulator does not pause, and customers compare you with firms carrying neither constraint.
The hard part in banking is not building something modern. It is building it beside a core nobody can take offline, under obligations that arrive on schedule whatever else is happening that quarter.
What we bring, and what it changes
Legacy cores, regulatory reporting and fraud controls compete for the same engineering budget, while customers judge the bank on the app in their hand.
Filed under FinanceFour demands on the same budget
The core
Decades of encoded business rules that work, are barely documented, and cannot be taken offline to be understood.
The regulator
Reporting cycles that arrive whatever else is happening, and that are still assembled by hand in most firms.
The threat
Fraud and security controls that have to keep improving against an adversary who is also improving.
The customer
Digital-first expectations set by firms with no legacy estate and no obligation to explain their decisions.
Moving off a core without a big-bang cutover
Every step below leaves a working system behind it. That is the constraint that makes the sequence what it is.
Encircle
Put an API layer in front of the core so new work stops writing to it directly.
Extract
Move one bounded capability out at a time, with the rules re-derived and tested against production behaviour.
Run both
Parallel operation with reconciliation, until the new path is demonstrably identical.
Retire
Decommission only what is provably unused — measured, not assumed.
Controls the delivery carries
- Authentication, authorization and least-privilege access
- Encryption in transit and at rest
- Immutable audit trails on every state change
- Data lineage from source to regulatory report
- Segregated environments and controlled release
- Monitoring and alerting on control failures
A pipeline, not a quarterly project
Regulatory reporting assembled by hand each cycle is expensive twice: once in the effort, and again in the risk that the version submitted cannot be reproduced six months later when somebody asks how a figure was reached.
Automating it means fixing lineage first — every figure traceable to the system that produced it — after which the report itself is a build step. The cycle gets shorter, and the answer to “where did this come from” stops requiring a person who remembers.
