03 / FAQ

Honest answers, plain

Both. Green-field is cleaner. Legacy requires more judgment. We enjoy both — and we don't rewrite things just because we didn't write them.

Yes. We have designers who work in code. Figma exists, but so does refinement in the actual product. Output is shipped interfaces, not pixel-perfect mockups.

Your choice. We can manage infrastructure (AWS, Vercel, self-hosted) or hand over a production-ready system for your team to operate.

We ship to 95+ Lighthouse across the board by default. LCP under 2.5s, INP under 200ms, CLS under 0.05 — not aspirational, baseline.
