FAQ

Do you build marketing sites or only apps?

We specialize in application engineering (authenticated products, workflows, data). Marketing sites can be paired, but the core value is production software.

Can you take over an existing codebase?

Yes. We start with a short technical audit, then propose a stabilization plan before new feature velocity.

How do you handle SLAs and uptime needs?

We define SLOs based on your stage—sensible alerting, runbooks, and incident response practices included for launches.

What’s included in QA?

Regression on critical paths, performance checks for high-risk endpoints, and accessibility basics for customer-facing flows.

How fast can we go live?

Many MVPs target ~8 weeks; larger platforms are milestone-driven with weekly demos throughout.
