React & Next.js
Development
We build production-grade web applications with React 19 and Next.js 15. Server Components, TypeScript-first architecture, and sub-second load times — engineered for scale from day one.
React Applications, Deconstructed
Single Page Apps
Blazing-fast React SPAs with client-side routing, state management via Zustand or Redux Toolkit, and optimistic UI updates. Code-split at route level for sub-second initial loads.
Server-Side Rendered
Next.js SSR pages that fetch data on every request. Perfect for dynamic content that needs SEO visibility and always-fresh data from your database or CMS.
Static Sites
Pre-rendered at build time with ISR for instant page loads. Marketing sites, documentation portals, and content-heavy pages that serve from the edge at zero compute cost.
Headless CMS
React frontends powered by Sanity, Contentful, or Strapi. Your content team edits in a familiar CMS while users experience a lightning-fast, modern interface.
API Development
Next.js API routes and Route Handlers for full-stack applications. tRPC or REST endpoints with Zod validation, rate limiting, and database integration via Prisma.
Progressive Web Apps
Installable web apps with offline support, push notifications, and native-like performance. Service workers, caching strategies, and app manifest configuration.
Our Technology Stack
From Concept to Production
Discovery
We map your requirements, user flows, and technical constraints. You receive a detailed architecture document, technology recommendations, and a fixed-price project estimate within 48 hours.
Architecture
Component hierarchy, data flow diagrams, API contracts, and database schema designed before a single line of code is written. We define the deployment strategy and CI/CD pipeline upfront.
Development
Agile sprints with weekly demos. TypeScript-first development, comprehensive component library, server and client component separation, and automated testing at every layer.
Testing
Unit tests with Vitest, integration tests with Playwright, and performance benchmarks against Core Web Vitals. Every PR runs through automated checks before merge.
Deployment
Production deployment to Vercel, AWS, or your infrastructure. Edge caching configuration, CDN setup, monitoring dashboards, and post-launch performance verification.
Headless Shopify
with Next.js
We build headless Shopify storefronts using Next.js and the Shopify Storefront API. Decouple your frontend from Liquid templates and gain complete design freedom, 10x faster page loads, and the ability to build custom checkout flows that convert at higher rates than standard Shopify themes.
Server Components fetch product data at the edge. ISR regenerates collection pages without rebuilding your entire site. Cart state syncs seamlessly with Shopify's backend.
Shopify Storefront API
GraphQL queries for products, collections, and cart operations with type-safe codegen.
Edge Rendering
Product pages rendered at the edge for sub-200ms TTFB globally, no matter where your customers are.
Custom Checkout
Branded checkout experiences with upsells, bundles, and subscription flows beyond Shopify defaults.
