EngineeringFront-end Development

Start building. While you’re still designing.

Our designers and frontend engineers work together from the start, using AI to create working prototypes and reusable code.

We carry validated components into production, reducing handoffs, rework and time to launch.

What do our engineers review?

Component structure, accessibility, responsive behavior, data states and performance. Suitable prototype code becomes part of the product after review and testing.

Move faster from design to product.

  • COLLABORATE

    Build during design.

    Explore interactions in working code, with engineers reviewing structure and feasibility early.

  • REUSE

    Reuse what works.

    Turn suitable prototype components into production code instead of rebuilding every screen.

  • DELIVER

    Keep delivery moving.

    Develop shared components and integrate real data while the design takes shape.

Our approach

One workflow from prototype to production.

  1. 01

    Align

    Designers and engineers agree on user flows, components and technical constraints before detailed implementation.

  2. 02

    Prototype

    Use AI to generate interfaces and test interactions. Engineers review the code as the design evolves.

  3. 03

    Build & integrate

    Reuse validated components, improve what needs work and connect APIs, application state and business logic.

  4. 04

    Test & release

    Check accessibility, performance and behavior across browsers and screen sizes. Ship and improve through real usage.

Why Cleevio

Less handoff. More progress.

We’ve been building products since 2008. Today, AI helps our designers and engineers work on the same implementation from the earliest stages.

Frontend developers review design-generated code from the start, guiding component structure, reuse and integration.

Our speed comes from overlapping design and development, reusing good code and catching issues early.

AI helps us build faster.

Our engineers own the implementation.

Our stack

A preferred stack. An open approach.
