02

Engineering

Typed React/Next.js, storybook or equivalent, API integration, and automated visual regression where ROI is clear.

03

Measure

Real-user monitoring, Lighthouse budgets, and iterative performance work after launch.

How custom frontend development engagements run

Custom frontends when templates are not enough, design systems, complex interactions, accessibility, and Core Web Vitals targets baked into the architecture. On Residency Road engagements, discovery maps dependencies and success metrics before sprint one. Architecture choices, API contracts, and observability hooks are documented before the first production deploy.

// FAQ

Custom Frontend Development questions

How do you keep custom frontends maintainable?+

Strict component boundaries, documented conventions, typed APIs, and CI checks, so new engineers onboard without tribal knowledge.

Do you work with our existing design files?+

Yes, Figma to code with design token alignment. We flag feasibility issues early rather than at QA.
