Cloud-Native Core Banking Platform Onboarding 100K Accounts in 6 Months for a Neobank
A neobank needed a cloud-native core banking platform that could scale from zero to 100K accounts. We built it on Azure Kubernetes with automated compliance monitoring — onboarding 100K accounts in 6 months.
About the Client
The Challenge
A neobank needed a cloud-native core banking platform that could scale from zero to 100K accounts. We built it on Azure Kubernetes with automated compliance monitoring — onboarding 100K accounts in 6 months. The organization faced mounting pressure from leadership to modernize. Existing systems and processes had reached their limits — manual workarounds consumed staff time, data quality was unreliable, and decision-makers lacked the visibility they needed.
The fintech industry added specific complexity: regulatory requirements (Industry-specific compliance, data privacy regulations, operational standards) demanded auditable processes and governance. Any technology change needed to maintain compliance continuity while delivering measurable improvement.
Previous attempts had stalled — either the technology was too complex for the internal team to maintain, the vendor didn't understand fintech industry requirements, or the project scope expanded until timelines became unrealistic. This time, the sponsor demanded a phased approach with measurable results within one quarter.
Our Approach
We designed a phased approach optimized for speed-to-value and compliance continuity:
Assessment (Weeks 1-2)
Application inventory, dependency mapping, and cloud readiness assessment. Migration wave planning.
Landing Zone (Weeks 2-4)
Deployed Azure landing zone with networking, security, and compliance controls.
Migration Execution (Weeks 3-9)
Phased migration — lift-and-shift, re-platform, and re-architect based on application needs.
Validation (Weeks 7-11)
Performance, security, and compliance testing.
Cutover & Handoff (Weeks 9-12)
Final cutover, knowledge transfer, runbook documentation, and operational monitoring setup.
Solution Architecture
Target: Azure with hub-spoke network, Azure AD identity, and compliance controls
Pattern: Phased migration waves with automated validation and rollback capability
Operations: Azure Monitor observability,

Key Takeaways
If your organization is facing a similar challenge, here's what we learned:
Phased delivery de-risks large projects. By scoping the initial deployment for 8-12 week delivery, we proved value before the executive sponsor's next quarterly review. This maintained budget authority and organizational support for subsequent phases.
Fintech domain expertise accelerates every phase. Understanding fintech terminology, regulations, and workflows eliminated weeks of discovery that generalist consultants require. Our cloud & devops team brought industry context from day one.
Change management is half the project. Technology implementations fail when users don't adopt. We embedded change management into every phase — from requirements workshops to training to post-go-live support. Adoption reached 80%+ within the first month.
Ongoing governance prevents regression. We established monthly review cadences, defined ownership for data quality and process adherence, and built dashboards that make issues visible before they become problems. The platform continues to deliver value because governance is sustained.
