Frontend: the user's first contact with the product

Frontend development is the user's first contact with your product. Performance, accessibility, and UX detail are decided here.

React + TypeScript + Tailwind CSS as the modern frontend stack. Component-based, tested, accessible, with a Lighthouse Performance >= 95 target.

Frontend architecture decisions

Modern frontend development hinges on: SPA, SSR, or hybrid? How is routing done? How is state managed? These decide the product's lifetime performance and dev speed.

For most enterprise frontends, Next.js + React + TypeScript is the healthiest path. Vite + React Router can be enough for SaaS dashboards and internal tools.

Performance optimization

Three pillars of frontend performance: bundle size, image optimization, network request management. Code splitting (route-based + component-based), tree shaking, dynamic import — all part of the standard package.

Image optimization via next/image, modern formats (AVIF, WebP), lazy loading, responsive srcset. Network requests handled with React Query cache, prefetching, optimistic UI. Result: a UX where the user never feels they're waiting.

Accessibility and WCAG 2.1 AA

Accessibility isn't only for vision-impaired users — it makes the experience better for all users. Keyboard navigation, focus management, screen-reader compatibility, contrast, dynamic type support.

We reference WCAG 2.1 AA; axe-core auto-runs on every PR. Manual checks (VoiceOver, NVDA, TalkBack with real experience) are also added.

Design system integration

Frontend stays in continuous contact with the design team. Design tokens defined in Figma (colors, typography, spacing, motion) reflect directly in Tailwind config; design changes ship in code in minutes.

Storybook becomes a sustainable UI documentation reviewable by the design team. Design review happens pre-merge; no rework cycle.

Frequently asked questions

Should I hire a frontend developer or full-stack?

A specialist frontend developer goes deeper on quality. A full-stack developer is more efficient for small teams; on larger projects frontend and backend separate.

Which CSS approach?

Tailwind CSS in most projects — performance and fast iteration. CSS-in-JS (vanilla-extract) when very complex design systems are required.

What does mobile-first mean?

We start design and dev from the smallest screen, then 'expand' to desktop. Result: mobile experience isn't an afterthought.

How important is animation?

Micro-interactions (hover, focus, click feedback) significantly raise UX quality. Large animations (page transitions) hurt performance unless optimized. We balance from day one.
