Phase 02 · Design & Build
A real, navigable version of your web app — every screen, every state, every interaction — built in production-grade code and wired to a mock data layer that mirrors your future database. The fastest way to see the product before engineering touches it.
Most projects lose months in the gap between “we have designs” and “engineering is ready to build.” We close that gap with a complete, clickable version of your web app — every screen rendered in production-grade React, every interaction wired up, every empty/loading/error state designed.
Underneath it runs on a structured mock-data layer that is intentionally modeled to mirror your eventual production schema (Postgres, Firestore, whichever you choose). When your backend team picks it up, the data contracts are already defined, the components are already built, and the only job left is to swap the mock layer for real endpoints.
The result: stakeholders, users, and investors get to use the product — not imagine it — before a single line of backend code is written.
Homepage, listing, detail, forms, confirmations — plus hover, loading, empty, error, and edge states designed and built.
Production React components with a real folder structure. Not throwaway mockup code — it ships into your repo and stays.
A mock data layer designed against the eventual database. Your backend team gets a working API spec for free.
Real routing between pages. Clickable, shareable, deep-linkable — behaves exactly like the final product.
Designed and tested on desktop, tablet, and mobile. Every layout adapts.
Typography, color, spacing, components — codified into a small design system that survives the engineering handoff.
Filters, sorts, search, modals, toasts, transitions. The polish that usually gets cut at the end is in from day one.
Static deploy, sharable URL, no backend dependency. Send the link to a customer, a stakeholder, or an investor.
Live URL, password-optional, ready to share with users, stakeholders, or investors.
React components, styles, mock data, build pipeline. Yours to keep, fork, and extend.
Tokens, primitives, and reusable components documented in a single place.
The shape of your future database, derived from real screens — not whiteboard guesses.
Images, icons, fonts — named, optimized, and ready for the engineering team to use as-is.
What to wire, what to swap, what to extend. Hand it to a backend team and they know what to do.
Structured feedback windows after the first walkthrough. Anything beyond is scoped separately.
Clear edges save weeks. Here’s what the Interactive Prototype is — and what it deliberately isn’t.
— You’re a founder approaching an engineering hire or contract, and want a finished frontend ready to hand them.
— You need to run usability tests, pitch to investors, or get internal sign-off on something that feels real.
— You have a Figma file that nobody can build from, and the project has stalled in the gap between design and code.
— You’re an agency or PM team that needs a frontend partner to land the work before backend kickoff.
Engagements start with a discovery sprint from $1,500, credited toward the full build if you proceed. Final quote depends on screen count and integration surface.
PRODUCT: Interactive Prototype TAGLINE: A real, navigable version of your web app — every screen, every state, every interaction — built in production-grade code and wired to a mock data layer that mirrors your future database. DESCRIPTION: Most projects lose months in the gap between "we have designs" and "engineering is ready to build." We close that gap with a complete, clickable version of your web app — every screen rendered in production-grade React, every interaction wired up, every empty/loading/error state designed. Underneath it runs on a structured mock-data layer modeled on your eventual production schema, so when your backend team picks it up, the data contracts are already defined and the components are already built. KEY FEATURES: • Every screen, every state — including hover, loading, empty, error, and edge cases • Real component architecture — production React, ships into your repo • Schema-shaped mock data — your backend team gets a working API spec for free • Multi-page navigation with real routing • Responsive across desktop, tablet, mobile • Brand-aligned visual design + small documented design system • Interactive micro-states: filters, sorts, search, modals, toasts, transitions • Runs anywhere — static deploy, shareable URL, no backend required DELIVERABLES: • Hosted clickable prototype (live URL) • Full source repository (React components, styles, mock data) • Component & design system file • Data schema document (derived from real screens) • Organized asset library • Engineering handoff document • Two rounds of structured revisions NOT INCLUDED: • Backend, database, server infrastructure • Auth, payments, third-party integrations • Production deploy with real users • Long-term hosting, SEO, analytics TIMELINE: 2–6 weeks INVESTMENT: From $5,000 DISCOVERY: Scoping sprint, from $1,500, credited toward full engagement
