What We Do
Curatos builds full-stack web applications with Next.js—the React framework that's become the industry standard for production web applications. We leverage Next.js's complete toolkit: server-side rendering, static generation, API routes, middleware, image optimization, and the App Router with React Server Components.
Our Next.js applications power everything from content-heavy marketing platforms to complex SaaS products serving thousands of concurrent users. We build with an eye toward performance, SEO, and developer experience—ensuring your application loads in milliseconds, ranks on search engines, and remains maintainable as your team and codebase grow.
We've built Next.js applications for fintech platforms processing real-time data, healthcare portals handling sensitive information, e-commerce sites optimizing for conversion, and B2B SaaS products with complex subscription logic.
Our Approach
Architecture & Tech Stack Selection
Every Next.js project starts with architecture. We evaluate your requirements—rendering strategy (SSR vs. SSG vs. ISR), data sources, authentication needs, third-party integrations—and design an architecture that leverages Next.js's strengths. We document tech stack decisions, including database choice, ORM selection, authentication provider, and deployment target.
App Router & Server Components
We build with the App Router and React Server Components as the default. Server components reduce client-side JavaScript, improve initial load performance, and simplify data fetching. Client components are used strategically for interactive elements—forms, animations, real-time features—creating the optimal balance of performance and interactivity.
Data Layer & API Design
Next.js API routes and Route Handlers serve as your backend API when needed. We design clean, typed API endpoints with proper validation, error handling, and rate limiting. For database access, we use Prisma or Drizzle ORM with PostgreSQL, implementing connection pooling and query optimization for production workloads.
UI Implementation
We build your UI with Tailwind CSS and a component library—either our custom components or established libraries like shadcn/ui or Radix. Every component is responsive, accessible, and optimized for performance. We implement streaming with Suspense boundaries to show progressive content loading rather than blank screens.
SEO & Performance Optimization
Next.js is an SEO powerhouse, and we exploit every advantage. Static pages are pre-rendered at build time. Dynamic pages use ISR (Incremental Static Regeneration) for freshness without sacrificing speed. We implement proper metadata APIs, Open Graph tags, JSON-LD schema, XML sitemaps, and robots.txt. Image optimization via next/image ensures perfect sizing and modern formats.
Testing & CI/CD
We set up comprehensive testing with Vitest for unit tests, React Testing Library for component tests, and Playwright for end-to-end tests. CI/CD pipelines run on GitHub Actions, with automated testing, linting, type checking, and preview deployments on every pull request.

Why Choose Curatos
Next.js is our primary framework. We've built dozens of production Next.js applications across the App Router's evolution. We understand Server Components, streaming, caching strategies, and the subtle performance considerations that make the difference between a good Next.js app and a great one.
We optimize for real-world performance. Lighthouse scores are nice, but we focus on real-user metrics—Time to Interactive, First Input Delay, and Largest Contentful Paint. Our applications feel fast because they are fast, not just because they're optimized for synthetic benchmarks.
We build the full stack. Next.js lets us own the entire application—from database to UI—without context-switching between frontend and backend teams. This means faster development, tighter integration, and fewer coordination overhead costs.
We implement security by default. Authentication, authorization, input validation, CSRF protection, rate limiting, and security headers are built into every project from day one. We don't treat security as an afterthought or an add-on.
We plan for scale. Our Next.js applications are designed to handle growth—more users, more features, more data. We implement caching strategies, database indexing, CDN configuration, and serverless deployment patterns that scale automatically.
