Our Process

How we build step by step

A structured process ensures nothing gets missed, from initial discovery to a fully optimized React launch.

  1. 01 Discover

    Discovery & Requirements Mapping

    User flows, component architecture, state management needs, and technical requirements mapped out before a single component is built.

  2. 02 Architect

    Component Architecture & SEO Strategy

    Component hierarchy, routing, rendering strategy (SSR, SSG, or CSR), and an SEO plan decided up front, so the app is fast, crawlable, and easy to extend.

  3. 03 Build

    Component Development & QA

    Reusable, typed components built with modern React patterns, tested across browsers and devices before it ever reaches staging.

  4. 04 Launch

    Launch & Optimization

    Bundle size audits, Core Web Vitals checks, analytics setup, and deployment. Plus 30-day post-launch support for refinements.

Client Voices

What it's like to work with us

We measure success in load times and rankings, not just how a component looks. Here's what a few clients had to say.

Our old React app took nine seconds to load on mobile because nobody had touched the bundle size in years. The rebuild came in under two.
Ananya Kapoor
Head of Product, WooCommerce
They handed off a codebase our own engineers actually enjoyed working in, with components that made every new feature faster to ship.
Rohan Mehta
Founder, Meridian Boutique
Migrating our jQuery tool to React felt daunting, but the transition was seamless and load times dropped almost overnight.

React gives you a component-based architecture that scales cleanly as an app grows, real interactivity without page reloads, and a single codebase you can share across web and mobile with React Native. WordPress and page builders suit content-heavy sites; React suits apps, dashboards, and products where interactivity and performance matter most.

Next.js adds server-side rendering, static generation, and routing out of the box, which matters if SEO or first-load speed is a priority, like a marketing site or storefront. Plain React (as a single-page app) suits internal tools and dashboards where SEO isn't a concern. We'll recommend the right setup during discovery.

A React marketing site or storefront typically takes 3–6 weeks; a full web application or React Native app usually takes 8–16 weeks depending on scope. We share a detailed timeline in our proposal before development begins.

A client-side-only React app is difficult for search engines to index well. We solve this with server-side rendering or static generation via Next.js, so your React site gets the SEO performance of a traditional site with the interactivity of a modern app.

Yes. We migrate jQuery, Angular, Vue, or legacy applications to React, either incrementally alongside the existing app or as a full rebuild, with a plan designed to avoid downtime for the business relying on it.

Yes. React Native lets us share business logic and, often, UI components between your web app and iOS/Android apps, which cuts development time and keeps both platforms in sync as features ship.

Yes. Upon receipt of final payment, full IP and the complete codebase transfer to you through your own Git repository and hosting account, no vendor lock-in.

We offer optional retainers for continued feature development, dependency updates, and bug fixes after launch. It's entirely opt-in, not bundled by default.
