Frontend Development That Users Remember
Create fast, accessible, and beautiful user interfaces. InterCode builds component-driven frontends with React and Next.js that deliver exceptional Core Web Vitals scores and seamless user experiences.
Interfaces That Perform and Delight
Your frontend is where users form their opinion of your product in the first seconds. InterCode builds frontends that load fast, respond instantly, and work flawlessly across every device and browser. We combine React and Next.js expertise with deep CSS knowledge and accessibility best practices to create interfaces that are both beautiful and inclusive.
Our frontend development goes beyond pixel-pushing. We build maintainable component libraries, implement design systems that keep UI consistent at scale, and optimize for Core Web Vitals so your pages rank well and convert better. Every component is typed with TypeScript, tested with Playwright, and documented for your team.
Whether you need a complete frontend rewrite, a design system implementation, or performance optimization for an existing application, InterCode delivers measurable improvements in speed, accessibility, and developer productivity.
What We Deliver
High-performance frontend development with a focus on quality and maintainability.
Component-Driven Architecture
Reusable, composable component libraries that scale with your product and reduce development time.
- Atomic design methodology
- Storybook documentation
Design System Implementation
Turn your design tokens and Figma components into a living code library your whole team can use.
- Figma-to-code pipeline
- Theme and variant support
Performance Optimization
Achieve top Core Web Vitals scores with code splitting, lazy loading, and rendering strategy optimization.
- LCP, FID, and CLS optimization
- Bundle analysis and reduction
Accessibility (WCAG 2.1)
Inclusive interfaces that meet WCAG 2.1 AA standards for screen readers, keyboards, and assistive technologies.
- Automated and manual a11y audits
- ARIA patterns and semantic HTML
SSR & SSG
Server-side rendering and static generation strategies that balance performance, SEO, and dynamic content needs.
- Next.js ISR and streaming SSR
- Edge rendering for global performance
Our Frontend Development Process
Design Review & Architecture
We analyze your designs and define the component architecture, state management, and rendering strategy.
- Component tree mapping
- State management plan
Design System Setup
Build the foundational component library with tokens, primitives, and documentation before feature development.
- Storybook and design tokens
- Theme configuration
Feature Implementation
Develop features as composed components with full TypeScript typing and responsive behavior.
- Mobile-first implementation
- Cross-browser testing
Performance & Accessibility Audit
Comprehensive audit of Lighthouse scores, bundle sizes, and WCAG compliance with remediation.
- Core Web Vitals optimization
- Screen reader testing
Testing & Deployment
Automated testing suite with visual regression, integration, and E2E tests before production deployment.
- Playwright E2E tests
- Visual regression with Chromatic

Technologies We Use
Modern frontend tools for fast development and production-grade performance.
React and Next.js are our core frontend stack for their ecosystem, performance capabilities, and developer experience. We complement them with TypeScript for type safety and Tailwind for rapid, consistent styling.
Client Results
Rebuilt a data-heavy dashboard achieving a 96 Lighthouse performance score, up from 52 in the legacy version.
Next.js migration with code splitting and image optimization cut average page load time by 40%.
Complete accessibility remediation brought the platform to full WCAG 2.1 AA compliance across 200+ pages.
Why InterCode for Frontend Development
Performance Obsessed
We optimize for Core Web Vitals from day one, not as an afterthought, because fast pages convert better and rank higher.
TypeScript Everywhere
Full TypeScript coverage means fewer runtime bugs, better IDE support, and safer refactoring as your codebase grows.
Accessibility Built In
WCAG 2.1 compliance is part of our development process, not a checkbox at the end of the project.
Design System Expertise
We build component libraries that keep UI consistent across teams and products, reducing design drift and speeding development.
Frequently Asked Questions
Yes. We collaborate closely with your designers through shared Figma files, design token handoff, and regular review sessions. Our developers understand design intent and flag implementation challenges early to avoid costly redesigns later.
Absolutely. We have migrated frontends from jQuery, Angular, and custom frameworks to React and Next.js. We use incremental migration strategies that let you ship improvements gradually rather than doing a risky big-bang rewrite.
We build a design system with documented components, design tokens, and Storybook. This creates a single source of truth for UI patterns that all developers reference. Visual regression tests catch unintended changes before they reach production.
Most of our projects achieve 90+ Lighthouse performance scores. Content-heavy pages with third-party scripts may score slightly lower, but we optimize aggressively and document the tradeoffs. We set specific performance budgets during project planning.
Yes. We use mobile-first responsive design as our standard approach. Every component is designed and tested across mobile, tablet, and desktop breakpoints. We test on real devices in addition to browser dev tools to catch platform-specific issues.
