Signs your frontend needs work
Is the interface quietly working against your product?
None of this points to a bad product idea or a weak backend. It points to the layer people actually see and touch, and every one of these is fixable with the right build.
06 failure points we design out of every build
- 01
Every interaction feels a beat too slow
Scroll stutters, animations drop frames, the first paint takes too long. Users read that lag as low quality, and most of them will not wait around to find out otherwise.
- 02
What shipped isn't what was approved
Small drifts in spacing, colour and type add up fast. By the time it's live, the product looks like a rough draft of the design your team signed off weeks earlier.
- 03
Mobile was an afterthought, and it shows
Shrinking a desktop layout is not the same as designing for mobile. Cramped touch targets and awkward scroll behaviour push away the majority of your traffic.
- 04
The codebase has become a liability
Legacy jQuery, tangled callbacks and no type safety turn every change into a gamble. A modern React or Vue foundation with TypeScript makes the code something a new hire can pick up in a day, not a month.
- 05
There's no system, just repetition
Without shared components and design tokens, every new page is built from scratch. That slows the team down and lets the UI drift out of sync with itself.
- 06
Accessibility and SEO were bolted on late
Missing labels, broken heading order and non-semantic markup quietly cost you both screen reader users and search rankings. Retrofitting is always harder than building it in from the start.

What we build
Our frontend development services
From a single component library to a full product UI migration, every engagement is scoped, tested and documented before it lands in your hands.
Vue.js Development
Vue 3 single-file components, Pinia for state and the Composition API, aimed at frontends that stay readable as they grow rather than getting harder to touch.
Next.js Development
Server-side rendering, static generation and hybrid rendering from one Next.js codebase. Fast by default, and built with search visibility in mind from the start.
Angular Development
Enterprise Angular builds with strict TypeScript, reactive forms and RxJS, structured so large teams can work in parallel without stepping on each other.
UI Component System Development
A documented library of reusable components with design tokens and Storybook coverage, so visual consistency holds as your product grows past the first release.
Performance & Core Web Vitals
Code splitting, lazy loading, bundle analysis and render-blocking cleanup aimed at green Core Web Vitals scores that hold up under real traffic, not just a Lighthouse run.
Frontend Redesign & Modernization
Move off legacy jQuery or Angular 1 onto a current framework while the app stays live, the data stays intact and your team keeps shipping through the transition.
Progressive Web App (PWA)
Service workers, manifest configuration and offline caching that make your web app installable and app-like on any device, no app store required.
TypeScript Migration
An incremental move from JavaScript to TypeScript with full type coverage, a strict config and a pattern guide so the whole codebase converges on one standard.
Accessibility Compliance (WCAG 2.1)
Semantic HTML, focus management, keyboard navigation and colour contrast checks, tested with real screen readers to hit WCAG 2.1 AA without watering down the design.
Frontend Testing
Unit tests with Jest, component tests with Testing Library and end-to-end coverage with Cypress or Playwright, built as a safety net your team can trust before every release.
Frontend Maintenance & Support
Dependency updates, security patches and browser compatibility checks backed by a helpdesk that actually responds, so the frontend stays current long after handover.
Why choose us
Frontend work held to a higher bar
Performance, accessibility and test coverage are requirements here, not extras that get cut when the timeline gets tight. This is what stands behind every frontend we ship.
Start your project-
We pick the framework, not our comfort zone
React, Vue, Next.js or Angular, we recommend whatever actually fits your project, your team and your timeline, not whichever we happen to reach for by default.
-
AI-driven speed, human-reviewed quality
AI-assisted tooling speeds up routine component work, and every performance budget is still enforced and reviewed by experienced engineers before it ships.
-
Pixel-accurate, whatever tool you design in
Figma, Sketch or Adobe XD, we translate the file into a working interface with exact fidelity to spacing, type and colour, not an approximation of it.
-
Accessible from the first component
Semantic HTML, correct ARIA and full keyboard support are built into components from day one. We do not treat accessibility as a pass we run before launch.
-
TypeScript by default, not by request
Every new project starts in strict-mode TypeScript. Better autocomplete, fewer runtime surprises, and refactors your team can make with confidence later.
-
Verified on real hardware
Chrome, Firefox, Safari, and actual iOS and Android devices, checked before anything reaches staging, not assumed to work because it worked in one browser.
-
Built from components, not from scratch each time
Every project ships with a documented component library, so new pages get assembled from what already exists instead of being rebuilt from zero.
-
Since 2008, still hands-on
Building software since 2008 for clients across the US, UK, Canada and India. We stay around for questions, dependency updates and new feature work long after the initial engagement ends.
How we work
Our frontend development process
Eight stages from design review to handover, each one producing something real you can check before we move to the next.
- 01
Discovery
We review your goals, technical constraints, existing codebase and current performance baseline before recommending anything.
- 02
Design review
Figma files get audited for component reuse, edge cases and responsive patterns before a single component is built.
- 03
Architecture
Component hierarchy, state management strategy and folder structure get agreed and documented up front.
- 04
Component build
Components built in isolation with tests and Storybook documentation, with AI-assisted tooling speeding up routine work without cutting corners.
- 05
API integration
Components get wired to real backend endpoints, complete with error states and loading skeletons, not just happy-path demos.
- 06
Testing & QA
Unit, integration and end-to-end tests run alongside cross-browser and cross-device checks.
- 07
Deployment
CI/CD pipeline configured, build output optimized, and the deployment verified before we call it done.
- 08
Handover
You get documentation, a component guide and a live knowledge-transfer session, not just a repo link.

Client words
Trusted by product teams that care about quality
Our React app got rewritten with TypeScript and a proper component structure, and the Lighthouse score jumped from 44 to 96. New engineers can actually make sense of the codebase now, which was never true before.
The Next.js build came in five weeks. Every screen matched our Figma files exactly, and the app cleared our WCAG audit without any follow-up work on our end.
Our Vue 3 migration had been stuck for months with a previous vendor. This team wrapped it in six weeks, added real TypeScript coverage, and left us with a test suite that actually passes. Night and day difference.

Questions, answered
Frontend development FAQs
How much does frontend development cost?
Frontend development is priced according to the project's requirements, complexity and level of customization. Smaller interfaces and component systems require less work, while full product frontends with advanced interactions and testing require more. We provide a detailed quote after reviewing your requirements.
Which frontend framework do you recommend?
It depends on your project and team. React and Next.js suit most product and marketing needs and have the largest hiring pool. Vue is a strong choice for teams that prefer a more opinionated structure. Angular suits large enterprise teams with strict consistency requirements. We recommend based on your context.
Can you work with our existing backend or API?
Yes. We work with REST APIs, GraphQL endpoints and third-party data sources. We review your API contracts early in the project and flag any issues before build begins.
How do you ensure frontend performance?
We set Lighthouse score targets at project start and enforce them. We use code splitting, lazy loading, image optimization, tree shaking and font subsetting as standard, and we audit the bundle before delivery.
Can you migrate our jQuery codebase to React or TypeScript?
Yes. We do incremental migrations, running old and new code side by side so the site stays live throughout. We establish patterns early and work through the codebase systematically rather than doing a risky big-bang rewrite.
Do you build design systems and component libraries?
Yes. We design and build component libraries with design tokens, Storybook documentation, variant coverage and usage guidelines. These become the foundation that makes future development faster and more consistent.
How do you handle accessibility?
We write semantic HTML, use proper ARIA roles and labels, test keyboard navigation and check colour contrast against WCAG 2.1 AA as a standard part of every build. We do not treat accessibility as an optional bolt-on.
Can you work directly from our Figma files?
Yes. We work from Figma as the source of truth. We audit files for completeness before build and flag ambiguous states, missing mobile designs or inconsistent spacing before they become build problems.
How long does frontend development take?
A component library takes 3 to 6 weeks. A full product frontend with testing and CI/CD typically takes 8 to 14 weeks. Timelines depend on scope, design readiness and API availability.
Do you write tests?
Yes. We write unit tests for logic, component tests with Testing Library and end-to-end tests with Cypress or Playwright. Test coverage is agreed at scoping and treated as part of the deliverable, not optional.
Can you help with state management?
Yes. We set up and advise on Redux Toolkit, Zustand, Pinia, Jotai or React Query depending on what your application actually needs. We do not default to complex state management when simpler options are sufficient.
What happens after the frontend launches?
We provide documentation, a component guide and a handover session. Most clients retain us for ongoing development, dependency updates and feature additions on a retainer or time-and-materials basis.
