Architecture Consultancy

We provide software architecture consultancy for businesses and development teams across the UK and Isle of Man. Practical guidance on system design, technology selection, and technical planning - from an engineer with over a decade of experience designing production systems.

Architecture decisions have a longer-lasting impact on a software system than almost any other engineering choice. The decisions made in the first weeks of a project - how components are structured, how data flows between them, where boundaries are drawn, which technologies are chosen - determine how much every subsequent decision costs. Getting architecture right at the start is significantly cheaper than fixing it later.

Every architecture engagement is led and delivered personally by Owen Jones, OLXR's founder and lead engineer. The guidance you receive reflects practical experience of designing systems that work in production under real conditions - not textbook patterns applied without regard for the constraints of your specific situation.

Who This Is For

Development teams starting a new system and wanting experienced input on the architectural approach before significant development begins
Businesses whose existing system architecture is creating problems - performance issues, difficulty adding features, or fragility under load
Non-technical founders who need to understand the architectural trade-offs of different approaches before committing to one
Teams at an architectural decision point - choosing between monolith and microservices, SQL and NoSQL, cloud providers - who want independent input
Organisations that have inherited a system with architectural problems and need a diagnosis and a plan for addressing them
Teams planning a cloud migration that needs architectural decisions made with the right long-term view

What We Deliver

System Architecture Design

Component diagrams, data flow design, API boundary definition, and technology selection for new systems.

Architecture Review

Assessment of existing system architecture with specific, prioritised recommendations for improvement.

Technology Selection Guidance

Independent evaluation of competing technologies, frameworks, and platforms for your specific requirements.

Architectural Decision Records

Documented rationale for key architectural decisions that provides context for future development.

Technical Roadmaps

Phased plans for addressing architectural debt or evolving a system's architecture over time.

Risk Assessment

Identification of architectural risks and their likely consequences if not addressed.

Integration Strategy

How the new system connects with your existing tools and data, decided before development begins.

Scalability Planning

Explicit planning for how the architecture handles growth in users, data, and functionality.

Our Approach

1
Assess Before Recommending

Architectural recommendations made without a thorough understanding of your specific requirements, constraints, and existing systems are not valuable - they are generic advice dressed up as specific guidance. We invest real time in understanding your situation before making any recommendations: what the system needs to do, what constraints it operates within, what the team's capabilities are, and what the cost of different failure modes would be. Only then do we recommend an architectural approach.

2
Practical Over Theoretically Correct

There is always a theoretically correct architectural approach to any problem. That approach is not always the right one for a specific team, timeline, and budget. We recommend the architecture that is right for your situation - which may be simpler than what current industry fashion suggests, or more sophisticated than what you currently have. The goal is an architecture that your team can build, maintain, and evolve reliably - not one that looks impressive on a conference slide.

3
Document for the Long Term

Architecture that lives only in the architect's head is architecture that will be misunderstood, ignored, or forgotten as the team changes. We document every architectural engagement thoroughly - the design itself, the alternatives that were considered and rejected, and the reasoning behind key decisions. That documentation is as valuable as the design, because it allows future developers to understand not just what was built but why.

Frequently Asked Questions

This is one of the most common architectural questions and one where the industry fashion often conflicts with practical wisdom. Microservices are appropriate for teams and systems of a certain scale and maturity - they introduce significant operational complexity that is only worth paying when the benefits of independent scaling and deployment genuinely apply to your situation. Most smaller teams building new systems are better served by a well-structured monolith that can be decomposed later if and when the scale genuinely justifies it. We will give you an honest assessment based on your specific situation.

Cloud architecture should be driven by the actual requirements of the system - the scalability needs, the reliability requirements, the operational complexity the team can support, and the cost profile. We design cloud architectures that are appropriate for your actual situation rather than defaulting to the most sophisticated available patterns. Managed services, serverless, containers, and traditional VMs all have their appropriate use cases, and the right answer depends on understanding your requirements in detail.

Yes - architecture reviews of existing systems are a common engagement. We assess the current architecture against the system's current and anticipated requirements, identify the specific issues that are causing problems or creating risk, and produce a prioritised set of recommendations with the rationale and the effort required for each. We are also honest about issues that are architectural debt you should accept rather than pay down, because not every architectural problem is worth fixing.
