Banking architecture review

De-risk core banking and digital banking architecture decisions.

Architecture decision support for core banking transformation, digital banking onboarding, retail and business banking integration, commercial lending systems, and payments modernization.

Buyer pain

Banking modernization breaks when ownership is implicit.

Core banking transformation, digital banking onboarding, retail and business banking integration, commercial lending systems, and business banking payments all depend on clear system boundaries and operational accountability.

Relevant background

Domain exposure without naming confidential clients.

Domain exposure across U.S. core banking transformation, Canadian digital banking onboarding, retail and business banking, credit-union platform integration across 20+ systems, commercial lending systems, and business banking payments.

What I review

Architecture decisions that need explicit ownership.

  • System-of-record boundaries
  • Retail and business onboarding flows
  • Integration contracts and ownership
  • Commercial lending system dependencies
  • Operational exception handling
  • Auditability, rollback, and cutover planning

Deliverables

Decision-ready outputs, not generic slideware.

  • Architecture decision memo
  • System boundary and dependency map
  • Risk register for onboarding, lending, payments, and cutover
  • Recommended path with owners and next actions

Patterns from prior work

Anonymized examples of the kind of architecture pressure this work is built for.

No client names, fake outcomes, or invented metrics. These are domain patterns and pressure points from prior work.

Core banking transformation

Worked across core banking modernization contexts where integration boundaries, cutover sequencing, reconciliation, and operational ownership had to be made explicit.

Digital banking onboarding

Experience across retail and business banking onboarding flows where many dependent systems needed consistent contracts, exception handling, and support paths.

Credit union integration

Experience with credit-union retail banking platform integration across 20+ systems, where system-of-record boundaries and cutover risk mattered.

What to send before a review

Useful context beats polished decks.

  • Current architecture diagram or rough sketch
  • Integration inventory
  • Known failure modes or incidents
  • Roadmap or migration plan
  • Constraints: budget, timeline, vendor/platform commitments
  • Decision that needs to be made
  • People who need to agree

What the first conversation should clarify

Enough clarity to choose the right review shape.

  • The decision being made
  • Systems and teams affected
  • Main risks
  • Missing information
  • Whether a short review is enough
  • Likely artifact: decision memo, risk register, readiness brief, or boundary map

Sample artifacts

Concrete working artifacts for review and action.

Stylized examples only. No client names, fake metrics, or confidential diagrams.

How the review works

A short path from context to recommendation.

01

Intake

Goals, constraints, current diagrams, backlog, operating concerns, and known failure points.

02

Architecture read-through

Boundaries, dependencies, contracts, data movement, failure modes, telemetry, rollback, and ownership.

03

Working session

Compare options, pressure-test assumptions, and align practical decision criteria.

04

Decision package

Memo, risk register, recommended path, and next actions with owners.
