Scope

ClickMasters builds production-grade frontend applications for B2B companies across the USA, Europe, Canada, and Australia. React SPAs with TypeScript, Zustand, and TanStack Query. Next.js web applications with App Router, Server Components, and sub-second Core Web Vitals. Design systems in Storybook that give your product and design teams a shared language.

What is Frontend Development?

Frontend development is the engineering discipline of building the user-facing layer of software. It encompasses everything users see and interact with in their browser from dashboards and data tables to the design system that defines the visual language. A frontend architecture is defined by decisions made before the first component is written: state management, data fetching, and performance targets. Correct early choices make the codebase easy to extend for years.

Key React Architecture Decisions

We follow a standardized default stack to ensure performance and maintainability, while remaining flexible for specific project constraints:

What this engagement delivers

React SPA Development

Single-Page Applications with TypeScript, Zustand, and TanStack Query. Component architecture focused on reusability, testability, and optimistic UI updates.

Next.js App Router

Modern web apps using Server Components to eliminate client-side waterfalls. Streaming UI, Metadata API for SEO, and Edge Network deployment.

Design System Development

Component libraries in Storybook with Chromatic visual regression. Design tokens from Figma to Tailwind CSS for a single source of truth.

Performance Optimization

Sub-second Core Web Vitals improvement. LCP optimization, CLS prevention, and bundle analysis to achieve Lighthouse 90+ scores.

Frontend Accessibility

Legal compliance with WCAG 2.1 AA. axe-core integrated into CI and manual screen reader testing for inclusive B2B products.

Modernization & Migration

Upgrading legacy React apps. CRA to Vite, Redux to Zustand, and JavaScript to TypeScript strict mode migrations without disrupting ops.

Process

  1. Phase 1 · Week 1

    Frontend Architecture

    Selecting framework (Next.js/Vite), rendering strategy, and state management boundaries in a formal document.

  2. Phase 2 · Week 1-3

    Component Foundation

    Establishing the design system in Storybook, extracting tokens from Figma, and building accessible UI primitives.

  3. Phase 3 · Week 2-8

    Agile Development

    Screen-by-screen build using Server Components and TanStack Query with unit tests and a11y checks.

  4. Phase 4 · Week 6-9

    Lighthouse Optimization

    Bundle analysis, image optimization, and script audits to pass the mandatory Lighthouse 90+ CI gate.

  5. Phase 5 · Week 7-9

    Accessibility Audit

    Full WCAG 2.1 AA audit with axe-core and manual screen reader testing (VoiceOver/NVDA).

  6. Phase 6 · Week 8-10

    Launch & RUM

    Playwright E2E tests, Vercel deployment, and Real User Monitoring (RUM) setup for Core Web Vitals.

How we work

Performance Enforced

Lighthouse 90+ CI gate | Basic: Post-launch aspiration

Accessibility Debt

WCAG 2.1 AA by default | Basic: Retrofitted after audit

Type Safety

TS Strict (Zero any) | Basic: any types everywhere

Visual Integrity

Chromatic Regression | Basic: Manual visual QA only

Architecture

Server Components First | Basic: Client-side waterfalls

Where this is used

SaaS Dashboards

Data-dense interfaces with Server Components for fast initial loads and real-time updates.

Fintech Products

Optimistic UI for transactions and strict TypeScript to prevent financial display bugs.

Healthcare Portals

WCAG 2.1 AA compliant clinical documentation tools with complex form logic.

Headless Commerce

Next.js frontends with ISR for sub-second product page loads and high search rankings.

FAQs

What is the difference between React and Next.js?

React is a UI library; Next.js is a framework built on top of it that adds SSR, SSG, and App Router for better performance and SEO.

Why does TypeScript matter for the frontend?

It catches type errors at compile time, provides better IntelliSense, and makes refactoring large codebases safe and predictable.

What is a design system?

A library of reusable UI components and tokens (Figma to Code) that ensures visual consistency and speeds up development across teams.

What are Core Web Vitals?

Google metrics (LCP, CLS, INP) that measure page load speed, visual stability, and interactivity. We enforce a 90+ Lighthouse score to ensure these are met.

How do you handle accessibility?

We build to WCAG 2.1 AA standards using semantic HTML, ARIA, and manual screen reader testing to ensure legal compliance and inclusive UX.

SSR vs SSG vs SPA?

SSR is for user-specific data; SSG is for maximum speed on marketing pages; SPA is for interactive tools without SEO needs. We use a hybrid approach.
