Anonymised experience note · Confirmed professional scope
Financial-core and internal-account modernisation
Architecture work at the intersection of banking transactions, internal and suspense accounts, settlement, reconciliation, financial posting and legacy dependencies.
Situation
A regulated banking environment needed a coherent view of how transaction events, accounting rules, interfaces and controls connected across established and target platforms.
Architecture contribution
Structured the current and target landscape, traced transaction-to-ledger flows, exposed dependencies and framed transition options for stakeholder review.
Artefact types
- Current-state and target-state architecture
- Transaction and posting-lineage map
- Interface and dependency register
- Migration options and decision record
Decision value
Separated platform change from the accounting, reconciliation and control obligations that still had to be satisfied, making gaps and preconditions easier to govern.
