Square

React Development Services

Square builds production React front-ends from our Tirana studio — single-page apps, dashboards and component libraries that stay fast as they grow. React is our default choice when the interface is the product: rich client-side state, real-time views, complex forms and design systems that several teams reuse. We work in TypeScript end to end, instrument Core Web Vitals from day one, and ship through your CI. You get a senior front-end team that shares your full CET working day, speaks fluent English and Italian, and bills at EUR 35-55/hour.

What we build

  • Single-page applications and data-heavy admin dashboards with client-side routing and granular state
  • Reusable component libraries and design-system implementations published as versioned packages
  • Real-time interfaces — live tables, charts and collaborative views over WebSockets or SSE
  • Complex multi-step forms with schema validation, optimistic updates and accessible interactions
  • Performance and accessibility hardening: code-splitting, lazy loading, Core Web Vitals and WCAG audits

Why this stack

  • Choose React when the UI carries the product — rich interactivity, live data and stateful flows that a server-rendered page can't handle gracefully
  • The largest front-end talent pool and ecosystem: any UI pattern you need already has a mature, maintained library
  • Component-driven architecture lets multiple teams share one design system and ship consistently
  • Full CET overlap means we pair, review and unblock UI work in the same working day as Rome and Milan
  • EUR 35-55/hour for senior React engineers, typically 30-60% below comparable Western-European front-end hires

Frequently asked questions

  • React or Next.js — which should we use?
    Use plain React (with Vite) for internal tools, dashboards and SaaS app shells where SEO is irrelevant and the whole thing lives behind a login. Choose Next.js when you need server rendering, public marketing pages or per-route data fetching. We help you decide on the first call and can mix both in one product.
  • Can you take over an existing React codebase?
    Yes. We start with an audit of your component structure, state management and bundle, then stabilise before adding features. Typical first wins are killing prop-drilling, introducing TanStack Query for server state, and fixing the Core Web Vitals that are hurting you.
  • How do you keep large React apps fast?
    Code-splitting per route, memoisation only where profiling proves it helps, virtualised lists for big tables, and a Lighthouse/Web Vitals budget enforced in CI so regressions fail the build rather than reaching production.
  • Do you build design systems or just screens?
    Both. We can deliver a versioned component library in Storybook with tokens, accessibility baked in and documentation, so your other teams build on a shared foundation instead of re-inventing buttons.
