Our expertise

The user interface (frontend) is the first thing your users see and interact with. A high-quality frontend experience—fast, responsive, intuitive, and visually appealing—is crucial for engagement and satisfaction. Geekworkers, a design agency tailor-made development in Lausanne, has a team of frontend developers passionate about creating modern web and mobile interfaces. We master HTML5, CSS3, JavaScript (ES6+) and cutting-edge frameworks like React, Vue.js, or Angular to build exceptional user experiences for your SME in Switzerland.

FAQs

The frontend is the showcase of your applicationIf the interface is slow, confusing, or doesn't display properly on mobile, users will become frustrated and leave. Good front-end development ensures a positive first impression and a pleasant interaction. Our experts in Lausanne are dedicated to this quality.

The choice depends on the size and complexity of the project, the existing ecosystem, and the team's preferences. react is very popular, flexible and benefits from a large ecosystem. Vue.js is appreciated for its simplicity and gentle learning curve. Angular is a more comprehensive and opinionated framework, often used for large enterprise applications. We recommend the best choice.

A SPA is a web application that loads a single initial HTML page, then dynamically updates the content when the user navigates, without reloading the entire page. This provides a much smoother and faster user experience, similar to a desktop or mobile application.

We adopt a “mobile-first” or “desktop-first” approach depending on the project, using responsive CSS techniques (media queries, Flexbox, Grid) to ensure the interface adapts perfectly to all screen sizes. Testing on different devices and browsers is carried out.

Yes. If your current frontend is slow, outdated, or no longer meets your needs, our developers in Lausanne can create a audit your code, suggest performance optimizations, or even a complete overhaul with more modern technologies. Contact us for a frontend development quote.
