Software and systems architecture
Architecture is a sequence of documented decisions, not a diagram. We accompany deep-tech projects from technical due diligence through the target picture to implementation support.
When it is worth it
Three situations keep coming up. Ahead of a larger investment, when the question is whether the plan holds in the intended form at all. During an acquisition or investment, when someone from outside has to judge what they are buying. And at the point where a system that grew over time can no longer be extended without every change breaking something elsewhere.
What is not worth it is a target picture for the drawer. An architecture document nobody touches after the presentation has not solved a problem, it has postponed one.
Decisions that come up
Build or buy. This is rarely decided on licence cost but on how closely the requirement sits to your business. What distinguishes you from competitors you should own; everything else is a case for a product.
Self-hosted or cloud. Operational effort against data sovereignty. For personal data the answer is often given; for everything else it is a genuine trade-off.
How much at once. Replacing a system in one move is quicker to plan and harder to rescue. Step-by-step replacement means a longer period of parallel operation but can be stopped at any point.
What gets written down. We record decisions as short entries with a date, the alternatives and the reasoning (ADRs). The value shows up later — when someone asks why something is the way it is, and the answer does not depend on a particular person being in the room.
What you get
- Technical due diligence and a survey of what exists
- Target architecture with a decision log (ADRs)
- Build-or-buy and self-hosting assessments
- Risks and effort estimates, named rather than omitted
- Implementation support and architecture reviews
How you know it holds
A decision can still be justified two years later without anyone reconstructing it from memory. A new developer understands the system from the documents rather than by word of mouth. And a change in one place stays a change in one place.
