System Architecture
Overview
Most architecture problems are not discovered in a review — they are discovered in production, under load, at the worst possible time. By then the fix is a migration rather than a decision.
We design the system before it is built, or reassess it before it is extended further: the data model, the service boundaries, the trust boundaries and the failure modes, written down with the reasoning attached so the design can be defended, not just diagrammed.
Capabilities
What system architecture covers
Architecture design and review
Service boundaries, data ownership and integration patterns decided deliberately, or an independent review of an existing design against your actual load and growth plans.
Data modelling
Schemas and storage choices made for the access patterns you actually have, not the ones a generic template assumes.
Threat modelling
Trust boundaries and data flows mapped so security decisions are made deliberately during design, not discovered during an audit.
Capacity and scaling plans
Sizing the architecture for the load you expect, with the specific points that will need to change identified before they become incidents.
Process
How we deliver it
The four stages system architecture moves through, and what you have at the end of each.
Understand the load
The current or expected traffic, data volumes and growth plans quantified, so the design is sized for a real number, not a guess.
Design the boundaries
Services, data ownership and trust boundaries decided together, with the reasoning for each written down.
Stress-test the design
The design checked against the failure cases and growth scenarios that are most likely to break it, before anything is built on top of it.
Document and hand over
Architecture decision records and diagrams your team can maintain and extend without needing the original conversation replayed to them.
Copy pending founder sign-off
PRD §8 requires the exact scope of each service to be confirmed before final copy. Outstanding for this one:
- Whether architecture review is offered as a standalone engagement or only alongside a build
- Typical engagement length and commercial model for architecture work
