10xbanking
Next-Generation SaaS Core Banking Platform & Distributed Settlement Ledger
Strangulated an 18-year-old COBOL mainframe monolith into an event-driven microservices architecture handling over €18B in daily settlements with sub-second exception triage.
Zero transaction loss across SEPA & SWIFT clearing
Legacy COBOL strangulated without a second of downtime
Autonomous deterministic DAG reconciliation
Distributed dual-write synchronization ledger
Tier-1 European commercial banks were bottlenecked by an 18-year-old COBOL and DB2 core banking mainframe. End-of-day batch settlement reconciliation took over 7 hours every night, during which customer balances froze and cross-border SEPA/SWIFT payments queued up in volatile staging buffers. Even minor schema updates or regulatory compliance mandates (such as instant SEPA mandates and Basel III liquidity disclosures) took 6 to 9 months of brittle testing cycles.
Over €18 billion in transactions flowed through this monolithic infrastructure every business day. A single locked database table or dropped settlement packet meant millions of euros in liquidity risk, penalties from the European Central Bank, and severe operational fallout. The client required a complete modernization strategy that strangulated the mainframe without interrupting 24/7 banking operations.
Core Workstreams Executed:
- Engineered zero-downtime Strangler Fig reverse-proxy gateways to intercept and route banking transactions dynamically.
- Deployed Kafka Streams distributed event brokers with guaranteed exactly-once processing (EOS) semantics.
- Constructed sub-second exception triage DAG state machines to automatically resolve clearing mismatches and IBAN validation errors.
- Implemented ClickHouse real-time audit storage and AWS CloudHSM cryptographic ledger signing for EU banking sovereignty.
Real-Time Settlement Volume & Clearing Velocity Telemetry
The live operations console provides instantaneous visibility into the €18.4B daily settlement stream. Each incoming SEPA, SWIFT, and instant payment transaction is tracked with microsecond-level ledger timestamps, eliminating overnight batch ambiguity.
- check_circle Sub-second settlement confirmation counters across 14 central bank clearing rails
- check_circle Continuous liquidity allocation meters preventing overdraft exposure in correspondent accounts
- check_circle Automated fraud and anti-money laundering (AML) pattern scoring within 45ms of transaction ingress
Autonomous Exception Resolution & Transaction Clearing Pipeline
A granular view into the autonomous settlement exception DAG. When a cross-border transaction fails initial validation, intelligent reconciliation agents diagnose the root cause, verify correspondent bank ledger entries, and auto-correct routing codes within 850 milliseconds.
- check_circle Automated reconciliation of 98.4% of transaction discrepancies without human intervention
- check_circle Deterministic audit trails with cryptographic nonces for regulatory ECB inspections
- check_circle Human-in-the-loop escalation dashboard for compliance edge-cases exceeding €2.5M threshold
To achieve zero downtime, we applied the Strangler Fig architectural pattern backed by dynamic shadow dual-writing. Ingress banking API calls pass through high-performance Envoy proxies. While the legacy mainframe processes the primary transaction, the modern Rust microservices receive an asynchronous clone to verify data parity in real time.
Once ledger parity achieved 100.000% mathematical concordance across 30 consecutive business days, write authorization was seamlessly transitioned to the event-driven microservices. All payment exception paths—such as mismatched bic codes, insufficient clearing liquidity, or time-out errors—are handled by deterministic Temporal DAG workflows.
