Need a Front-End Developer Who Can Take Over a Sleek, User-friendly UI?

Front-end engineers who take over live codebases, design systems and data-heavy dashboards in the framework you already use.

Front-end developers screened on interfaces already in production

Cortance's front-end developers are screened on interfaces they have already shipped to paying users: dashboards, design systems, checkout flows and admin panels. Of the 40+ front-end developers in our network, 20+ are senior, and most of their 176 listed projects are built in React and TypeScript, with Angular and Vue.js as smaller, deeper specialisms.


We hire for that history because a front-end rarely fails in the first sprint. It fails when a table that rendered 50 rows now has to render 10,000, when a second product starts reusing the same buttons, or when a framework upgrade lands in the middle of a release. The profiles below were matched on project evidence for those situations, not on a list of frameworks.


Front-end developers who can take over a codebase that is already live


Most front-end briefs we see start with existing code, not a blank repository. Oleksandra K., a senior Angular engineer, was a key contributor to the incremental move from AngularJS to modern Angular on Boostr, an ad-management platform whose sales and finance teams kept working through the migration. She built Angular components with backwards-compatible APIs so the old AngularJS modules could use them, and optimised grid rendering, filtering and pagination for datasets of 10,000+ rows. Mykhailo Y. led the front-end architecture of EssayPro and 25+ white-label brands serving 1.5M+ users, and moved legacy Angular and Ionic apps into an Nx monorepo, which cut deployment build time from about 20 minutes to 10 to 14. The mistake we screen against is the big-bang rewrite: a team freezes features for months to replace the framework and the business stops shipping. We look for engineers who have migrated module by module while the product stayed in use.


Who owns the design system when several products share one UI?


A shared component library pays off only when someone treats it as a product. Narek H. built and maintained the Ucraft design system in React, Storybook and shadcn/ui, with theming and accessible, documented components, and then used it on the Ucraft e-commerce dashboard, where he led the refactor into a modular architecture and integrated Stripe, Braintree, Revolut, Square and PayTabs. Gustavo M. contributed to the design system and performance work on Yalo's customer data and marketing platforms, the interface that sits on top of its AI sales agents. When a client tells us several teams will reuse the same UI, we look for this kind of Storybook and component-API history before anything else.


E-commerce, fintech and healthcare: where our front-end work clusters


Among the front-end projects on our network with an industry tag, the top three are e-commerce, fintech and healthcare. That mix shapes what we check. For e-commerce, we ask about product catalogues, carts and payment flows, for fintech and banking, about role-based access and real-time data, for healthcare, about forms that cannot lose data halfway. Volodymyr S. built a marketplace admin panel for merchant data and transaction audits, and covered it with Jest unit tests and Cypress end-to-end tests. Testing depth is not uniform across the team: more than half of the developers on our front-end team list Jest, Cypress or Playwright, so when your brief needs automated UI tests, we match on that explicitly rather than assuming it.


Send the stack and the problem, not only the framework


Tell us which framework and version you run, whether the work is new features, a migration or a design system, and who reviews front-end pull requests today. That brief decides the shortlist more than a framework keyword does. You interview the developers you like, and every profile has already passed our vetting process.

React, Angular or Vue: which front-end developer does your product need?

Hire for the framework your codebase already runs, and choose a new one only when you start from scratch. In our network, 37 front-end developers have React projects on their profile, 6 have Angular and 4 have Vue.js, so the answer also affects how many profiles you can compare.


React and Next.js fit most product and SaaS work, and the hiring market is widest there. The risk with React is the freedom it gives: two senior React developers can structure state in incompatible ways, so we ask candidates to explain how they split server data, UI state and forms on a past project.


Angular fits large, data-heavy business applications where many developers must follow the same structure: finance dashboards, CRMs, admin systems with detailed roles and permissions. Our Angular engineers are fewer, and they tend to come with RxJS, NgRx and migration history, including AngularJS codebases that still run in production.


Vue.js and Nuxt fit teams that want a smaller learning curve, and they turn up in our network in dashboards, marketing sites and products where one developer covers the whole front end. If your product runs on Vue, expect a shorter shortlist than for React, so tell us early and we will widen the search to full-stack developers with Vue projects.


If you are still choosing, the question to settle first is who will maintain the code in two years. Our React.js, Angular and Vue.js pages show the developers for each.

Accessibility and page speed are front-end work, and the EU now enforces one of them

The European Accessibility Act came into effect in June 2025 and covers e-commerce platforms and banking and payment services, according to the European Commission. For a product sold in the EU, keyboard navigation, screen-reader labels and focus handling are now requirements, and they are built in the front end.


This is work our engineers have done. Volodymyr S. re-engineered core UI components for WCAG compliance across a micro-frontend architecture on a fintech and e-commerce platform, including keyboard navigation for users who do not use a mouse. Mykhailo Y. set WCAG AA/AAA accessibility standards across a LegalTech document-drafting platform and grew its Jest unit test coverage from about 20% to over 80%.


Page speed follows the same logic. On EssayPro, Mykhailo deployed React and Next.js applications with server-side rendering, using a shared design system, and achieved Lighthouse and PageSpeed scores of 95 to 100. The trade-off we explain to clients: an accessibility or performance fix is cheapest when the component library is built for it, and most expensive when it is patched page by page after launch.

What AI coding tools change in front-end work, and what they leave to the developer

AI coding assistants save the most time on repetitive front-end tasks: scaffolding components, writing unit tests for existing code, and navigating a large, unfamiliar repository. They are less effective where the front end meets a person: a layout that breaks at one screen width, focus that moves in the wrong order for a screen-reader user, or a state bug that appears only after a slow network response.


Senior engineers on our front-end team list Claude Code, Cursor and GitHub Copilot on their profiles. For example, Oleksandra K. used Claude Code and Cursor on Datarails, a financial planning platform, where she redesigned the access-control system and added real-time UI updates over WebSockets. Mykhailo Y. used the same tools on EssayPro. In both cases, the engineer kept the architecture decisions. That is how we treat AI tooling when we match: a speed-up for a developer who can already judge the output, not a substitute for one.
