Architecture Consulting

Hands-on software and solution architecture consulting from practitioners who design, build, and govern complex systems.

Architecture consulting at Xtrable is not a slide-deck exercise. Our architects have spent decades designing, building, and operating complex systems across banking, financial services, e-commerce, legal, and public sector. We bring that experience to every engagement, working alongside your teams to produce architecture that is traceable, implementable, and built to last.

Architecture Must Be Implementable

The best architecture in the world is worthless if it cannot be built by the teams who need to deliver it. We design for real teams, real constraints, and real timelines.

Every recommendation comes with trade-off analysis, implementation guidance, and a clear path from design to delivery. We do not leave you with a document and a handshake.

What We Do

Solution Architecture

End-to-end system design from requirements through to deployment architecture. Service decomposition, integration strategy, technology selection, and non-functional requirements analysis.

System Decomposition

Breaking monolithic or tightly-coupled systems into well-bounded services with clear contracts. Domain-driven design, bounded context mapping, and ownership models.

Integration Architecture

API design, event-driven architecture, message broker selection, and integration platform strategy. Contract-first design with schema governance.

Security Architecture

Threat modelling, security control design, identity and access management architecture, and secure-by-design patterns for systems handling sensitive data.

Platform Architecture

Internal developer platform design, container orchestration architecture, CI/CD pipeline design, and infrastructure-as-code strategy.

Architecture Governance

Governance frameworks that balance control with delivery velocity. Architecture decision records, review processes, and compliance mapping that add value rather than bureaucracy.

Our Architecture Process

Every architecture engagement follows a structured process designed to produce implementable outcomes, not shelf-ware.

  1. Discovery and Current-State Assessment. We map your existing architecture by working with your teams, reading code, and understanding the actual system, not the aspirational documentation. We identify constraints, risks, and dependencies that will shape the solution.
  2. Architecture Design. We design the target architecture collaboratively, documenting every decision with explicit trade-off analysis. Designs are captured in NeoArc Studio as explorable, connected models rather than static diagrams.
  3. Validation and Proof. For high-risk decisions, we validate the architecture through prototyping, load testing, or structured walkthroughs with implementation teams. Architecture that has not been tested against reality is theory.
  4. Implementation Support. We stay involved through implementation, providing architecture guidance, code review, and design oversight. We ensure the built system matches the designed system.
  5. Knowledge Transfer. All architecture models, decision records, and documentation are handed over in NeoArc Studio format. Your teams have full ownership and can evolve the architecture independently.

Engagement Types

Architecture Review

A focused assessment of your existing architecture. We identify risks, technical debt, scalability concerns, and governance gaps. Delivered as a structured report with prioritised recommendations and a roadmap for improvement.

Greenfield System Design

End-to-end architecture for new systems. From requirements analysis through technology selection to deployment architecture. We design systems that are built for change, not just for launch.

Modernisation and Migration

Architecture for migrating from legacy systems to modern platforms. Current-state mapping, target-state design, phased migration planning, and risk mitigation strategies.

Architecture Practice Setup

Establishing or maturing an architecture practice within your organisation. Governance frameworks, tooling selection, role definitions, and process design tailored to your organisational culture.

Embedded Architecture

An Xtrable architect embedded in your team for an extended period. Working alongside your engineers, providing day-to-day architecture guidance, and building internal capability.

Where to start

Most engagements begin with a brief discovery call to understand your architecture landscape and the outcomes you need. From there, we scope an engagement that fits. No commitment required to start the conversation.
