The Problem

Why many frontends frustrate

Slow Loading Times

Bloated JavaScript bundles, unoptimized images, no lazy loading. Users do not wait.

Not usable on mobile

"Responsive" does not automatically mean "usable". Touch targets too small, scroll problems, layout breaks.

Browser Inconsistency

Looks good in Chrome, broken in Safari. Edge? Firefox? Was never tested.

Not accessible

No keyboard navigation, missing ARIA labels, too low contrast. Many users are excluded.

My Services

Frontend Development that works

From component architecture to pixel – I develop frontends that users love.

Vincent Kilchherr - Frontend Entwickler Schweiz

Full-Stack with Frontend Focus

I understand not only CSS and JavaScript, but also what happens behind the scenes. This helps build performant and maintainable frontends.

Whether React SPA, Vue.js components or classic JavaScript with modern tooling – I choose the right technology for your project.

  • React, Vue.js, TypeScript, Vanilla JS
  • CSS/SCSS, Tailwind, Bootstrap
  • Webpack, Vite, modern build tools
Component Development

Modern Component Architecture

Reusable, testable components with React or Vue.js. Clean code that is still understandable months later.

  • React & Vue.js – Depending on project requirements
  • TypeScript – Type safety for fewer bugs
  • State Management – Redux, Pinia, Context API
  • Testing – Unit and integration tests

Responsive Design

Perfect on every device

Mobile First does not simply mean "make it smaller". I develop layouts that work optimally on every screen.

  • Mobile First – Smartphone as starting point
  • Touch-optimized – Large buttons, natural gestures
  • Fluid Layouts – No fixed breakpoints
  • Device Testing – Real devices, not just emulator

User Experience

Intuitive User Interfaces

A good interface explains itself. I develop UIs that are intuitive and enjoyable – without users having to think.

  • Micro-Interactions – Feedback for every action
  • Loading States – Users always know what is happening
  • Error Handling – Helpful error messages
  • Accessibility – Built in from the start

FAQ

Frequently Asked Questions about Frontend Development

React or Vue.js – what do you recommend?
It depends on the project. React has a larger ecosystem and is common in enterprise projects. Vue.js has a gentler learning curve and is well-suited for smaller teams. Both are excellent frameworks.
How much does frontend development cost?
It depends on the scope – from simple projects to complex SPAs with many components. After the briefing you receive a detailed quote.
Do you also work with existing designs?
Yes, of course. I implement Figma, Sketch or XD designs pixel-perfectly. Or I work directly with your UI/UX designer.
What about performance?
Performance is not an afterthought. I optimize from the start: code splitting, tree shaking, optimized images, lazy loading. The goal is green Core Web Vitals.
Do you also integrate backend APIs?
Yes, I am a full-stack developer. I can not only consume APIs but also build them if needed. REST, GraphQL – whatever is needed.
How long does a frontend project take?
A simple project: 2-4 weeks. A complex dashboard or SPA: 2-3 months. After the requirements analysis I give you a realistic timeline.
