I work on banking transformations where target architecture, legacy constraints, regulation and production reality must coexist.
Case studies are published anonymously. Every figure derives from an internal evidence register and carries its qualification when it is a declaration rather than a supported fact.
Greenfield · BIAN-aligned · Production
A seven-layer BIAN-aligned banking architecture, industrialised into a repeatable API and service delivery capability operated by multidisciplinary teams. In production as of September 2026.
Brownfield · Cloud + on-premise · Active
Enterprise and transition architecture for a banking landscape combining cloud, on-premise appliances and legacy systems: capability and core assessment, baseline and target architectures, transition plateaus, work packages and a governed roadmap.
Decision instrument · Decision cycle complete
A formal conformity assessment established a stop line before cluster creation, identifying three irreversible blockers and assigning named owners to fifteen conditions.
Incremental modernization · Active
Progressive runtime modernisation that preserves consumer contracts through mediation, so schedule risk is no longer coupled to consumer migration.
Security architecture · Active
Key custody and rotation architecture for a fraud engine that depends on deterministic encrypted correlation, replacing a permanent rotation exemption with bounded, declared degradation.
Architecture automation · Active
An agentic pipeline with retrieval over a BIAN corpus and cross-validation rules between phases, enforcing traceability from business capability to implementation artifact.
Organizational capability · Active
An SFIA-anchored technical career framework with role cards, assessment scorecards, a junior onboarding programme and a campus in operation.
