Hire senior React developers

Developers for the interfaces that are hard to get right: data-heavy dashboards, design systems used by several teams, and screens that must work with a keyboard and a screen reader.

Short answer

elitics provides senior React developers from Prishtina for data-heavy interfaces, design systems and accessibility work, written in TypeScript with Zustand, TanStack Query and automated tests. You interview the developers, they start about 48 hours after you approve their profiles, and team extension costs €45–65 an hour, with a two-week trial and a free replacement if someone is not the right fit.

What our React developers build

Data-heavy dashboards
Tables with thousands of rows, filters, charts and live updates that stay responsive on an ordinary laptop.
Design systems
Component libraries with tokens, documentation and visual tests, shared by several product teams.
Accessibility fixes
Audits and remediation for keyboard use, focus handling, labels and contrast, ahead of procurement or regulatory checks.
Moving off old tooling
Create React App and class components moved to Vite or Next.js and hooks, without freezing feature work.

What a senior React developer should own

React itself is small. Seniority shows in how state, rendering and testing are organised as the app grows.

State in the right place
Server data in a query cache, UI state close to where it is used, and global state kept to a minimum.
Rendering performance
Profiling before optimising, virtualised long lists, stable props, and work moved out of render.
Accessible components
Native elements first, ARIA patterns where needed, visible focus and full keyboard support.
Tests that catch regressions
Component tests with Testing Library for behaviour, Playwright for critical user journeys, and visual checks for the design system.

Questions to ask a React developer

Ask for examples from code they wrote. These questions separate experience from tutorials.

  1. 01

    Where should data from the API live?

    In a server-state cache such as TanStack Query, not copied into global state. A strong answer covers invalidation after mutations and optimistic updates.

  2. 02

    A table re-renders on every keystroke. What do you do?

    Measure with the React Profiler, find unstable props or context values, then memoise or move state down. Virtualise if the list is long.

  3. 03

    How do you build an accessible custom dropdown?

    Use a native select if possible; otherwise follow the ARIA combobox or listbox pattern with keyboard support and focus management, and test with a screen reader.

  4. 04

    What do you test with Testing Library, and what with Playwright?

    Component behaviour as a user sees it in Testing Library; full journeys such as sign-up or checkout in Playwright against a running app.

  5. 05

    How would you retire Create React App in a live product?

    Move the build to Vite or Next.js first with no code changes, then upgrade dependencies and patterns gradually behind tests.

How hiring an engineer works

  1. 01

    Tell us the role

    Stack, seniority, start date and the hours you need to share. A call with our engineering lead takes 30 minutes.

  2. 02

    Review profiles

    You receive engineer profiles matched to your stack and interview the ones you choose.

  3. 03

    Start in about 48 hours

    NDA and IP assignment are signed, and the engineers are set up in your repositories and tools.

  4. 04

    Two-week trial

    If you are not satisfied, you do not pay for those two weeks. An engineer who is not the right fit is replaced at no extra cost.

Dedicated squad

A cross-functional team (product, engineering, QA, DevOps) that owns a product or feature.

Best when

You want a product built or rebuilt without growing headcount.

Build-Operate-Transfer

Your own development center in Kosovo, set up and run by us.

Best when

You plan a long-term engineering presence in Europe.

Common questions

Do your React developers also work with Next.js?

Yes. Next.js is our default for new web products. For single-page applications, embedded widgets or existing setups, we work in plain React with Vite.

Can they work with our designers in Figma?

Yes. They work from your Figma files and design tokens, raise questions in your design review, and keep components in sync with the design system.

Do they write tests?

Yes. Every project has automated tests and a CI pipeline, and every change goes through code review before it is merged.

How much overlap is there with our working day?

With Central European teams the whole day is shared; with London, eight hours. Check your city in our overlap tool.
