Core Banking Infrastructure Modernization

Old cores don’t crack — they calcify. We carved tunnels through bedrock without shaking the vault.

Retired Service

🔹 Expertise

Legacy banking systems don’t whisper — they creak. And when billions pass through outdated infrastructure, every second of latency echoes as lost value.
This project was the silent backbone of a $200M+ core system transformation, executed across multiple states and banking entities.
The mission wasn’t just modernization — it was resurrection.

We didn’t just migrate code. We migrated trust.

🔹 Brief

Zions Bancorporation, one of the largest regional banks in the U.S., needed to escape the gravity of its aging COBOL-based mainframes.
The stakes were enormous: modernize a real-time core banking system for seven affiliate banks, preserve continuity across millions of accounts, and meet future-ready demands — all without pausing the heartbeat of daily operations.

🔹 Goals

  • Replace legacy batch-processing core with real-time architecture
  • Reduce systemic downtime across all financial products
  • Migrate existing customers and transactions without data loss
  • Establish new DevOps pipelines for sustainable long-term growth
  • Ensure compliance with FDIC, OCC, and internal regulatory standards

🔹 Approach

We built bridges before tearing down walls.
First came a full diagnostic of the FutureCore roadmap — hundreds of workflows across retail, commercial, and investment divisions. Then we orchestrated a phased deployment of digital twins, allowing us to simulate real-world scenarios before go-live.

Our internal QA frameworks rivaled external auditors in precision. Regression testing was executed at scale. Downtime windows were orchestrated like ballet.
At the heart of it all: human coordination across vendor teams, internal stakeholders, and federal compliance officers.

🔹 Solutions We Offered

  • Legacy-to-real-time migration frameworks (FIS to Finastra)
  • End-to-end product lifecycle testing and defect triage
  • PMO-aligned Agile workflows with JIRA and Confluence
  • Zero-downtime release protocols across 7 affiliate banks
  • Stakeholder training, support, and compliance documentation
  • Live defect war rooms and escalation pathways
  • Infrastructure redundancy planning and execution
