Stack & infra
Concrete language, framework, datastore, and cloud topology recommendations.
Documents, not chat transcripts
Requirements, back-of-envelope capacity math, a Mermaid architecture diagram, API and data model, deep dives, failure modes and a scaling path.
Opinionated, with receipts
Every major decision names the rejected alternative and the trade-off that decided it. Assumptions are stated, never hidden.
Where it is strong, and where it is not
Reliable
- Structuring a vague idea into a reviewable design document.
- Surfacing the failure modes and edge cases you forgot.
- Naming trade-offs and defending a specific choice.
- Critiquing an existing architecture against a rigorous checklist.
Treat with care
- Capacity numbers are order-of-magnitude sanity checks, not benchmarks.
- Cost estimates need your real pricing and usage data.
- It cannot know your org, legacy systems, or team skills unless you say.
- Final architectural accountability stays with you.
