Architecture and modernization consultants

Senior architects who help you make sound technical decisions, reduce technical debt and modernize legacy systems in steps the business can absorb, and who stay involved while the plan is implemented.

How does SwedQ approach architecture and modernization?

We start by understanding the current system, constraints and business goals, then agree a target direction and a sequence of changes. Decisions are documented, the roadmap is practical rather than theoretical, and the same architects can support the teams that implement it.

Architecture assessment

An assessment gives a shared, honest picture of where the system stands. We review structure, dependencies, deployment, data flows, security and operational characteristics, interview the people who build and run it, and summarize the risks and opportunities in plain language.

Architecture disciplines

The type of architecture work depends on the decision you need to make.

Solution architecture

Designing a specific system or capability so that it meets functional, security and operational requirements.

Enterprise architecture

Aligning systems, capabilities and investments across the organization, without heavy frameworks for their own sake.

Integration architecture

Choosing how systems exchange data: APIs, events, batch or integration platforms, and who owns each contract.

Domain-driven design

Finding domain boundaries that let teams work independently and keep models understandable.

Technical debt and legacy modernization

Technical debt is only a problem where it slows change or creates risk. We help you identify which parts of the system matter most and choose the right approach for each one.

Retain: keep as it is when it works and changes rarely.
Refactor: improve in place where the structure is sound but the code is not.
Replace incrementally: route functionality to new components piece by piece, for example with the strangler pattern.
Rebuild or retire: when the cost of keeping the system is higher than replacing or removing it.

Migration planning

A migration plan describes the order of changes, the dependencies between them, how data moves and how risk is controlled at each step. We plan for parallel running, rollback options and cutover so the business keeps operating throughout.

Decision records and practical roadmaps

Important decisions are captured as architecture decision records: the context, the options considered and the reason for the choice. The roadmap links those decisions to concrete work items that teams can plan, rather than a target picture without a path.

Hands-on support during implementation

Architecture fails when it is handed over and left. SwedQ architects can remain with the implementing teams to review designs, resolve questions early and adjust the plan when reality differs from the assumptions. If you need engineering capacity as well, the work can continue with a SwedQ delivery team.

Frequently asked questions

How long does an architecture assessment take?

It depends on the size of the system and how much documentation exists. The scope and duration are agreed before the work starts.

Do you only advise, or do you also implement?

Both. Architects can work in an advisory role, and SwedQ can also provide engineers or a delivery team to implement the roadmap.

Do you work with specific architecture frameworks?

We use established practices such as domain-driven design and decision records where they help, and adapt to frameworks you already use rather than introducing new ones for their own sake.
