Hire Frontend Developers — React & TypeScript Specialists

A frontend developer focuses on the engineering side — component architecture, state management, performance, and testing. A UI/UX developer sits closer to the design–engineering boundary, specialising in translating Figma designs with pixel precision and implementing interaction patterns. Kultrix can provide either profile, or both, depending on your team's needs.

Most engagements start within 48 hours of contract signing. We keep available capacity specifically for this. For larger teams or specialised framework requirements, one week is typical.

Yes — TypeScript is mandatory on all new Kultrix frontend projects. It catches bugs at compile time, improves IDE productivity, and makes large React codebases significantly easier to refactor. Our developers configure strict mode, shared tsconfig presets, and typed API clients as standard.

Yes. Our developers are experienced with Radix UI, shadcn/ui, Material UI, Ant Design, Chakra UI, and custom internal systems. They adopt your existing patterns, extend your token system, and avoid introducing conflicting abstractions into the codebase.

Server state is managed with React Query or SWR — avoiding redundant local copies of API data. Global UI state is handled with Zustand or Redux Toolkit. Local component state stays in useState and useReducer. We apply the principle of keeping state as close to where it is used as possible.

Core Web Vitals optimisation is part of every Kultrix frontend engagement. We audit Largest Contentful Paint, Cumulative Layout Shift, and Interaction to Next Paint using Lighthouse and PageSpeed Insights, then apply targeted fixes: image optimisation, font loading strategy, lazy loading, and eliminating render-blocking resources.

Yes. Responsive design is a baseline expectation at Kultrix. Our developers build mobile-first layouts using Tailwind CSS utility classes or CSS Grid and Flexbox, test across device sizes in Chrome DevTools and real devices, and ensure that touch interactions, tap targets, and font sizes meet usability standards on small screens.

Yes. We write E2E tests with Playwright for critical user flows — authentication, checkout, onboarding, and other high-stakes paths. Playwright tests run in CI on every pull request and block merges when they fail, giving you strong regression protection without manual QA overhead.

Yes. Our developers are experienced with Scrum and Kanban workflows. They join standups, estimate user stories, demo work at sprint reviews, and contribute to retrospectives. They use your project management tool (Jira, Linear, Notion) and communicate primarily through Slack or your preferred channel.

The minimum engagement is one month. This allows enough time to onboard properly, contribute meaningfully, and assess the fit. Most clients renew after the first month, and many engagements run for six to twelve months.

Every developer passes a structured technical screen and a practical coding challenge before joining the Kultrix bench. We also match based on domain experience — a developer who has built fintech dashboards will be a better fit for your fintech product than a generalist. If a placement is not working within the first two weeks, we replace at no charge.

A retainer locks in a fixed number of developer hours per month at a fixed monthly fee, giving you guaranteed availability and a lower effective rate. Time-and-materials is billed weekly against actual tracked hours — more flexible for projects with variable workload. Both models include transparent reporting and a dedicated account manager.
