Front end development services for fast, accessible products
Senior front-end teams that fix the layer your users touch: architecture, design systems, performance, accessibility and migrations across React, Vue and Angular.
By the Ryz Labs team · Updated October 2026
Ryz Labs is a front end development company for the work underneath your screens: front-end architecture, design systems, Core Web Vitals, WCAG accessibility, framework migrations across React, Vue and Angular, and micro-frontends for many teams shipping one product. A dedicated team of senior front-end engineers, each in the top 1% of the tens of thousands we have interviewed, does the work in your repos on US business hours, with same-day code review.
What we build
Our front-end teams take a front-end problem with a finish line and solve it in production. If you need a whole new web application with its back end, that is our web development services. These engagements focus on the front-end layer itself:
- Front-end architecture reviews and rebuilds: a written decision record for rendering (SSR, SSG, streaming, client-only), routing, data fetching, state and styling, followed by the refactor that makes the codebase match it.
- Design systems used by more than one team: design tokens synced from Figma with Style Dictionary, accessible components, Storybook documentation, semantic versioning and a release process so product teams upgrade on their own schedule.
- Framework-agnostic component libraries: web components built with Lit or Stencil when the same button has to work in a React app, an Angular admin tool and a legacy server-rendered page.
- Core Web Vitals programs: field data from the Chrome UX Report and real-user monitoring, a fix list ranked by traffic, and changes that move LCP, INP and CLS on the pages that earn revenue.
- Accessibility remediation: an audit against WCAG 2.2 AA, fixes in the shared components first so they spread everywhere, and automated checks that keep regressions out.
- Framework migrations: AngularJS to Angular or React, Vue 2 to Vue 3, Create React App to Vite or Next.js, Pages Router to App Router, moved route by route behind feature flags.
- Micro-frontends: Module Federation, single-spa or route-level composition when separate teams truly need separate deploys, with a shared shell, shared dependencies and contracts between them.
How an engagement works
- Talk. A scoping call with your front-end or platform lead. We look at your framework versions, build tooling, design process, analytics and the metric that defines success: a Web Vitals threshold, an accessibility level, a deprecated framework turned off.
- Match. We propose a team scoped to your stack: senior front-end engineers with the right framework depth, plus a product designer or QA automation engineer when the work needs one. You get a plan, a price and the names of the people.
- Join. The team works in your repos, your CI, your Slack and your standups, and demos weekly against a real environment.
- Grow. Add people when a second product area joins the migration, or hand the system to your team with documentation, codemods and a walkthrough.
Week 1 is baselines: Lighthouse and field Web Vitals for top routes, a bundle-size report, an axe scan, and an inventory of components and their duplicates. Month 1 usually means the architecture or migration plan is written down and the first routes or components are live behind flags. By month 3, the budgets and checks run in CI on every pull request, and the remaining work is a backlog your team can see and size.
The stack our teams work in
| Layer | Tools we use | Notes |
|---|
| Frameworks | React, Next.js, Vue 3, Nuxt, Angular, Svelte, Astro | We work in the framework you have and say plainly when a migration is worth it |
| Build and monorepo | Vite, webpack, Turbopack, Nx, Turborepo, pnpm workspaces | Module Federation and single-spa only when separate deploys are needed |
| Design systems | Figma variables, Style Dictionary, Storybook, Lit, Stencil, Radix UI, React Aria | Tokens shared between design and code |
| Styling | CSS custom properties, Tailwind CSS, CSS Modules, Sass | Container queries and cascade layers where browsers allow |
| Accessibility | axe-core, Pa11y, Lighthouse, NVDA, VoiceOver | Automated checks plus manual keyboard and screen-reader passes |
| Testing | Vitest, Jest, Testing Library, Playwright, Chromatic | Visual regression for every shared component |
| Performance and monitoring | web-vitals library, Chrome UX Report, Lighthouse CI, Sentry, Datadog RUM | Field data decides priorities, not lab scores alone |
How we keep front ends fast and accessible as they grow
Front ends rarely fail on launch day. They fail by drift: each team adds a dependency, a one-off component and a third-party script, and two years later the main route is slow and the checkout fails a screen reader. A senior team stops the drift with checks, not good intentions:
- INP regressions. Interaction to Next Paint replaced First Input Delay as a Core Web Vital in 2024, and it punishes long main-thread tasks. We find them with the Performance panel and long-animation-frame data, then break up work, yield to the browser and move heavy logic off the main thread.
- LCP lost to images and fonts. We set priority hints on the hero image, serve AVIF or WebP at the right size, preload the one font that matters and stop layout-blocking requests.
- Layout shift. Reserved space for ads, embeds and late banners, explicit image dimensions and font-display rules keep CLS near zero.
- Third-party script creep. Tag managers grow quietly. We audit every script by cost, load the rest after interaction, and give marketing a budget they can see.
- Design-system forks. When product teams copy a component instead of upgrading it, the system dies. Versioned packages, codemods for breaking changes and a changelog people read keep teams on the current release.
- Accessibility that breaks on the next release. Fixing a modal once is easy. We fix focus management and ARIA in the shared primitive, then add axe checks and Playwright keyboard tests so it stays fixed.
- Migrations that never finish. Two frameworks running side by side for years doubles the cost of every change. We track remaining routes on a dashboard, delete old code as each route moves and agree on a cut-off date with your leads.
- Micro-frontends adopted too early. Separate deploys add runtime cost and version conflicts. We start with a modular monorepo and split only where team boundaries require it.
Team shapes and cost
Typical Ryz pricing is $7,000 to $15,000 per engineer per month. Mid-level engineers (comparable to Amazon L5) run $7,000 to $10,000; seniors (comparable to Amazon L6) run $10,000 to $15,000; leads start at $15,000 and are quoted per team. Monthly cost is headcount times rate, and project cost is team size times duration times monthly rate.
- Performance or accessibility team: 2 senior front-end engineers. 2 × $10,000–$15,000 = $20,000–$30,000 per month.
- Design system team: 1 tech lead, 2 senior front-end engineers and 1 product designer. $15,000+ for the lead, plus 3 × $10,000–$15,000 = from about $45,000–$60,000 per month.
- Migration program (several product areas moving off a legacy framework): 1 lead, 4 senior front-end engineers and 1 QA automation engineer, quoted per team after scoping.
Quotes are scoped per team. Before anything starts, you get a plan, a price and the names of the people who would do the work.
Dedicated team or staff augmentation?
Choose a dedicated development team when the work has a finish line: a migration with a cut-off date, a design system at version 1.0, a Web Vitals target on your top templates. The team owns the plan and reports in weekly demos.
Choose staff augmentation when your front-end lead owns the roadmap and needs more senior hands. Then you hire front-end developers who join your team, take tickets from your backlog and follow your conventions. If your codebase is React-only and you need product features rather than platform work, our React development services are the closer match.
When Ryz isn't the right fit
If you need a marketing landing page built this week, or an hourly freelancer from a self-serve marketplace, a freelance platform will suit you better. If your team needs coverage in European or Asian time zones, or follow-the-sun support, a global network is a better match. And if you want a branding or creative agency to define your visual identity, that is not what we do; our teams build and ship the front end.

FAQ
How much do front end development services cost with Ryz?
Ryz engineers typically cost $7,000 to $15,000 per engineer per month: $7,000 to $10,000 for mid-level, $10,000 to $15,000 for senior, and $15,000 and up for leads, quoted per team. A two-person senior front-end team is $20,000 to $30,000 per month. Project cost is team size times duration times monthly rate, and you get a scoped plan, a price and names before you start.
How quickly can a front-end team start?
After the scoping call we propose a team with named engineers. Most of the timeline depends on scope and your onboarding: repository and analytics access, environments, security reviews and how soon your design leads are available. We don't promise a start date before we have seen those.
How is this different from web development services?
Web development covers whole applications, back end and infrastructure included. Front end development services focus on the layer users touch: architecture, design systems, performance, accessibility and migrations, usually in a product that already exists.
Can you make our site meet WCAG 2.2 AA?
Our engineers audit against WCAG 2.2 AA, fix issues in shared components first and add automated and manual checks to every release. We don't issue legal certifications; for a formal conformance statement, pair our work with an independent accessibility auditor.
Should we move to micro-frontends?
Only if separate teams need to deploy independently and a shared release is blocking them. For most companies a modular monorepo with clear ownership gives the same benefits at lower runtime cost. We will tell you which one fits after looking at your teams and your build.
