Software Architecture Design & Consulting
Software architecture design. Microservices, event-driven, CQRS, DDD. Architecture audits, technical documentation, C4 diagrams.
Software architecture is the design of a system's structure - its modules, layers and services - ensuring scalability, security and maintainability.
Challenge
Your system is growing but its architecture can't keep up. Lack of clear structure leads to technical debt, scaling difficulties, and costly rework with every new feature.
Our Solution
We design architecture tailored to your business scale and needs. We apply proven patterns: microservices, event-driven architecture, CQRS, and DDD. We create C4 diagrams, technical documentation, and audit existing systems.
Result
A scalable, well-documented system architecture with clear module boundaries. Faster feature development, easier developer onboarding, and significantly reduced technical debt.
What we do in software architecture
Architecture is the set of decisions hardest to change later - so it pays to make them deliberately. We help with:
- Designing the architecture of a new system from scratch
- Choosing the approach: monolith, modular monolith or microservices
- Applying patterns (event-driven, CQRS, DDD) where they genuinely help
- Creating clear documentation and diagrams (the C4 model)
- Auditing and refactoring existing architecture
We don't design for its own sake - we match solutions to the scale and real needs of your business.
When it's worth bringing in an architect
Architecture pays off most when you take care of it early. A good moment is:
- The start of a new, larger system meant to run for years
- The point where every new feature takes more and more time
- A plan to scale to higher traffic or a larger team
- Recurring failures and difficulty finding their cause
- Preparing to split a monolith or to modernise
If you recognise even some of these situations, a few days of an architect's work can save months of later rework.
How we approach architecture design
We start by understanding the business, not by drawing boxes. Architecture should serve the company's goals, not the other way around.
- We learn the business domain, requirements and constraints
- We identify the key system boundaries (Domain-Driven Design)
- We match the architecture style and patterns to the real scale
- We document the decisions and their rationale (C4 diagrams, ADRs)
- We plan the rollout in stages, with room to evolve
We avoid unnecessary complexity - the best architecture is the one the team understands and can develop.
Auditing existing architecture
You don't always have to build from scratch - often it's enough to tidy up what already works.
- A review of the code, dependencies and system structure
- Identification of performance bottlenecks and risk points
- An assessment of technical debt and its impact on development
- Recommendations: what to fix first for the greatest effect
- A refactoring plan you can apply without stopping development
An audit gives you a clear picture of the system's state and a concrete list of actions ranked by return on investment.
What you gain from good architecture
Good architecture is invisible day to day, but its absence is felt with every change.
- Faster development of new features without constant firefighting
- Easier scaling as traffic and the team grow
- Less technical debt and lower maintenance costs
- Easier onboarding of new developers thanks to a clear structure
- Fewer failures and simpler root-cause analysis
It is an investment that pays back with every further feature and every new team member.
How much an architecture project or audit costs
Cooperation can be arranged as a one-off audit, a new system's architecture design or ongoing architectural support for the team. An audit is usually several days; the architecture design of a larger system is split into stages.
We bill on a Time & Material basis at 120 PLN/h net, with full transparency of the hours. We often start with a short audit that in itself delivers concrete value and a basis for further decisions.
Ongoing architectural support is also possible from 1,000 PLN net per month - decision reviews and consultations on key changes.
Frequently Asked Questions
Programming is building features, while architecture is the decisions about the structure of the whole system - how to split it into parts, how they should communicate and how it should grow. Good architectural decisions are the hardest to change later, so it pays to make them deliberately.
Not always. Microservices solve specific problems of scale and organisation but add complexity. For many systems a well-designed monolith or modular monolith is the better choice. We advise honestly, based on your scale.
Yes. We review the code, dependencies and structure, identify bottlenecks and technical debt, and then present a concrete list of recommendations ranked by return on investment.
Yes. We often act as architectural support for an existing team - we design, document and consult on decisions while your team handles implementation. We can also build the solution end to end.
