Custom web development with React.js
We build fast, reliable, and scalable web applications with React, Next.js and modern JavaScript stack. We approach strategically – from architecture and UX to integrations, testing and long-term support.
Highlights
Business focus
Result-oriented specifications, KPIs and measurable value.
Architecture & security
SPA/MPA, SSR/SSG/ISR, App Router vs. Pages, mono/multi-repo.
Speed & SEO
Core Web Vitals, fast loading, structured data.
Long-term support
Evolution plans, monitoring and SLA.
What does the service include
Custom web applications
We create SPA/MPA solutions with React, which address specific business processes – portals, control panels, CRM/ERP interfaces, configurators, interactive catalogs.
Next.js websites
We build high-performance websites with SSR/SSG/ISR. Next is better suited for websites due to built-in server rendering, better indexing and SEO advantages.
View the Next.js service →Design system & component library
We create reusable UI components with Storybook, Radix, Tailwind/SCSS and Design Tokens.
Integrations and microservices
Integrations with REST/GraphQL, SaaS platforms, payment systems, CMS/Headless and cloud services. Appropriate responsibility division through API Gateway.
Quality & automation
TypeScript, ESLint/Prettier, Jest/Testing Library, Playwright, GitHub Actions, CI/CD, preview environments and feature flags.
Support & development
SLA, bug fixes, optimizations, updates of dependencies, performance monitoring and security.

Tech stack
Why Next.js is better for websites
SEO & indexing
Server-side rendering (SSR) and static generation (SSG) give search engines full content at the first render. This improves crawl‑ability and visibility.
Performance
We use Image/Font optimizations, caching, edge middleware and Incremental Static Regeneration (ISR) for real fast websites.
Scalability
App Router, server actions and responsibility division facilitate scaling and team‑based development.
Conversion
Faster pages and better UX → higher conversion and ROI, especially for content websites and eCommerce.
