Frontend development

We implement high-quality interfaces with optimal performance and an excellent user experience.

The code the user sees and feels.

What it involves

Our frontend team turns designs into real digital products with obsessive attention to detail. We specialise in modern technologies such as React and Next.js, delivering applications that are fast, accessible and maintainable in the long run.

This is for you if…
  • You have Figma designs ready to turn into code
  • Your site loads slowly or has poor Core Web Vitals
  • You need a design system implemented in code
  • You want product-grade animations and interactions
  • Your current frontend is hard to maintain or scale
How we work

Our methodology,
paso a paso

01

Design review

We go through the design files, identify the components and define the project structure and the design system.

02

Project setup

Architecture, static analysis tooling, testing and CI pipelines configured before the first line of business logic.

03

Component development

Bottom-up construction: atomic components first, then composites, and finally the pages.

04

Optimisation

Performance audit, bundle size reduction, lazy loading, image optimisation and Core Web Vitals improvements.

05

Delivery and documentation

Storybook with every component documented, test coverage and an onboarding guide for the team.

Frequently asked questions

Everything you need to know

We specialise in React and Next.js, though we also have experience with Vue.js and Svelte where the project calls for it.

Mandatory code reviews, component tests, static analysis with ESLint and strict TypeScript across every project.
