Software architecture & strategy

Software architecture that grows with your business and outlasts technology shifts.

Bad software architecture costs silently — weeks of delay per feature, bugs you can't catch, migrations that never happen. We help you design or repair a software architecture that scales with your business and de-risks technology decisions for the years ahead.

What you get

Concrete, not abstract.

Architecture reviews

We analyse your existing architecture — strengths, bottlenecks, risks — and deliver a concrete improvement roadmap. Not just a list of problems, but prioritised steps.

Technology evaluation

.NET, Node, or Java? Microservices or monolith? Own frontend or headless CMS? We deliver a grounded decision document.

Domain-driven design

When complexity can't be refactored away, structured modelling helps. Bounded contexts, ubiquitous language, event storming — applied pragmatically, not dogmatically.

Microservices vs. monolith

We tell you honestly when the overhead is worth it and when it isn't. Microservices aren't a silver bullet — a well-structured monolith beats a tangled service mess.

Migration strategies

From legacy to modern, without a big bang. Strangler-fig pattern, gradual replacement, parallel paths — we pick the strategy that fits your reality.

Reducing technical debt

We identify debt, prioritise refactorings, and slot the work into the sprint plan. Debt doesn't have to be paid all at once — but it can't be ignored.

What we work with

Technologies.

We pick the technology based on your needs — these are our daily tools.

  • DDD
  • Event Storming
  • C4 model
  • ADRs
  • Modulithic monolith
  • Microservices

Frequently asked

Common questions about this service.

  • When is an architecture review worth it?

    Before you sink a lot of money into an architecture that won't carry the load — or when the team notices features taking longer and longer to ship. A review typically runs one to two weeks and delivers a prioritised roadmap, not just a list of problems.

  • Microservices or monolith — what do you recommend?

    Usually a modular monolith, until growth genuinely justifies microservices. We see too many projects start with microservices and suffocate in distributed complexity. The call is made case-by-case against actual scaling and team realities.

  • How do you help with technical debt?

    Identification and prioritisation of debt, then continuous reduction baked into the sprint plan — no big-bang refactor. We turn implicit, dangerous debt into documented, controllable debt that gets paid down step by step.

  • What is software erosion and how do you address it?

    Software erosion is the gradual decay of an originally clean architecture under the pressure of changing requirements. We address it with Architecture Decision Records, architecture tests in CI, and regular reviews — preventive rather than reactive.

  • Can I book you for a second opinion?

    Yes. We assess architecture decisions from an outside perspective — typically two to five days with a concrete assessment report. Risks are named clearly without us auto-pitching for follow-up work.
