What Building In-House gets wrong in Financial Services
Core banking modernization in-house is one of the most ambitious technology programs a bank can undertake. The failure mode is well-documented: the bank assembles a team of strong engineers who do not have core banking migration experience, the architectural decisions that are obvious to experienced core banking engineers are not obvious to the in-house team, and the project discovers the gaps during a live-parallel cutover that cannot be stopped.
BSA/AML transaction monitoring systems built in-house face a specific talent gap: the engineers who understand FinCEN regulatory requirements and can architect a production transaction monitoring system from those requirements are specialists. Hiring one is possible. Hiring a team that can deliver a production system on a regulatory deadline is a different challenge — and most banks are competing for the same small pool of engineers.
The regulatory examination risk of in-house banking technology development is real. An OCC technology examination that identifies architecture gaps in a core system or a BSA/AML monitoring system creates a remediation obligation with a regulatory timeline. The in-house team that built the system may not have the expertise to remediate it quickly.
What we deploy instead
We provide the core banking engineering team that would take 18 months to assemble internally — with production experience in core banking migration, BSA/AML architecture, and the operational constraints of systems that cannot go down.
Fixed-price engagements with defined architectural milestones. The first milestone is always a working integration with your core system in a sandbox environment.
SOC 2 and PCI DSS built into the architecture from day one — enforced automatically by ALICE at every commit.
Fixed-price engagements. Production system in 8-20 weeks. No discovery phase. No change orders.
Domain-qualified engineers with financial services experience. The senior engineer who scopes the engagement is the senior engineer who delivers it.
Full source code and documentation transferred at close. No licensing. No managed services dependency.
The compliance difference
BSA/AML, GLBA, PCI DSS, Basel III, SOC 2. Banking compliance requires engineers who have built compliant systems — not engineers who have read the compliance requirements. We build systems that pass OCC examinations.
What switching from Building In-House looks like
Banking technology engagement: 16-24 weeks for a core modernization. Team: 12-20 engineers. Fixed price. Full IP transfer.
Architecture review and scope definition. We review existing deliverables and identify gaps.
Scope locked, team assembled, first sprint underway. Working code from week two.
First production milestone — a working integration or system component, not a document.
Full IP transfer. Source code, documentation, operational runbooks. Your team runs the system.
