Financial products where correctness is the feature
Money movement, reconciliation and audit trails, built so that every number can be explained after the fact.
What this domain does to the build
The stack is broadly the same everywhere. These are the parts that are not, and they are usually where an estimate goes wrong.
- Every balance change needs an immutable trail — “what did this look like on the 3rd” must be answerable
- Reconciliation is not a report, it is a system, and it has to run whether or not anyone looks
- Regulatory requirements land on data residency, retention and KYC, and they change the architecture
- Idempotency is mandatory: a retried request must never move money twice
What we typically build here
- Ledger and double-entry data models
- Payment gateway and bank integrations
- Audit logging and reconciliation jobs
- Security review against authorisation and isolation failures
