01
Core modernisation without a destabilising cutover
Create governed service boundaries around critical systems, move change to observable interfaces and retire risk in controlled stages.
Industry / FS
Engineering financial systems where speed, evidence and control must coexist.
Financial institutions operate across core platforms, market infrastructure, payment rails, data estates and regulatory obligations that rarely change at the same speed.
Operating context
Technology has to fit the institution around it.
Financial institutions operate across core platforms, market infrastructure, payment rails, data estates and regulatory obligations that rarely change at the same speed.
The engineering challenge is to improve decision latency and service velocity while preserving traceability, segregation of duties, operational resilience and human authority over material risk.
Operating agenda
Priorities that shape the architecture.
We translate operating risk and commercial objectives into explicit system boundaries, evidence and decision ownership.
02
Decision systems with accountable risk ownership
Use AI and advanced analytics for forecasting, detection and prioritisation while keeping policy, limits and approvals explicit.
03
Real-time transaction infrastructure
Design payment, settlement and market-data systems for deterministic state, reconciliation, recoverability and evidence.
Engineering contribution
Where Root Digit contributes.
Each engagement is scoped around a real operating decision, a controlled technical boundary and evidence that leadership can review.
FS.1
Banking and market-platform engineering
Event-driven services and data products around customer, account, order, portfolio and ledger domains.
- Domain decomposition and APIs
- Workflow and rules engines
- Ledger and reconciliation services
FS.2
Risk, surveillance and financial intelligence
Decision-support systems that combine live data, model ensembles and controlled review workflows.
- Forecasting and scenario systems
- Fraud and anomaly detection
- Human-approved risk workflows
FS.3
Payments and digital-asset infrastructure
Payment orchestration and distributed-ledger systems built around key control, finality and exception handling.
- Payment and settlement orchestration
- Smart-contract engineering
- Custody and signing architecture
FS.4
Data control and regulatory evidence
Lineage, access, reporting and observability that make operational decisions reconstructable.
- Data lineage and quality controls
- Regulatory workflow automation
- Audit-ready event histories
Control plane
Controls designed with the system.
Assurance is part of the architecture and operating model—not a review added after delivery.
01
Model governance
Versioned models, evaluation records, monitored drift and explicit decision authority.
02
Transaction integrity
Idempotency, reconciliation, finality rules and independently recoverable state.
03
Security boundaries
Segregated duties, hardware-backed identity, least privilege and protected signing paths.
04
Operational resilience
Capacity evidence, failure testing, recovery objectives and observable dependencies.
Practical entry points
Start with one decision that matters.
01
Modernise one high-change domain
Place a governed service boundary around a core workflow without replacing the entire estate.
02
Prove one decision system
Evaluate a model against real prevalence, cost asymmetry and a defined human approval path.
03
Re-engineer a transaction path
Map state, finality, exceptions and recovery before changing throughput or user experience.
