Frequently asked questions

Can I interview developers before hiring?

Absolutely. You interview, optionally run a paid test sprint, and only commit when you're satisfied. No pressure.

What pricing models do you offer for Software Architect engineers?

Monthly retainer for ongoing work, starting at $10k/month for a single senior engineer. Hourly for short engagements. Fixed-price for project-scoped work.

What tools do your Software Architect developers use?

Jira, GitHub, GitLab, Linear, Slack, Notion — we adapt to your stack, not the other way around.

Are developers full-time on our project?

Yes — dedicated full-time, not shared across clients.

Can we scale up or down?

Scale up with new engineers onboarded in 48h. Scale down with two weeks notice. No contractual lock-in.

Is this a consulting engagement or a development engagement?

Both. We can deliver architecture artifacts only (documents, diagrams, ADRs), or architect + build — where the same person designs and leads the implementation.

What does a typical architecture engagement look like?

Kick-off → 2-week discovery (existing codebase + infrastructure audit) → Architecture Design Document + RFC → review session → optional implementation phase.
