Vertical slices over horizontal layers
Sprints stall when one week is “only API” and the next is “only UI.” Ship thin vertical slices that a stakeholder can click. That forces early decisions about empty states, errors, and auth — the places projects usually hide risk.
Reviewable pull requests
Large PRs hide defects and slow feedback. Keep changes reviewable, with screenshots or short clips for UI work. Code review is part of delivery quality, not a gate invented at the end.
Staging that tells the truth
If staging configuration drifts from production, go-live becomes archaeology. Match env vars, feature flags, and third-party sandbox credentials closely enough that surprises are rare.
Performance is a product requirement
Bundle size, image strategy, and route-level code splitting belong in acceptance criteria for customer-facing React apps. Performance work deferred to “later” becomes a launch blocker with no calendar left.
Dedicated React capacity when the roadmap moves
When priorities change weekly, a dedicated React pod that already knows your design system and API quirks outperforms a new fixed bid every quarter. Pair that capacity with clear product ownership on your side so engineers are not inventing the roadmap alone.
