Interval Splitter

Front-end developer (technical test)

Client: Eurocontrol

Dec 2024

The technical test for Eurocontrol, built as a small React app.

Enter a start and an end breakpoint: the app splits the range into intervals drawn as bars whose width is proportional to their length
The splitting algorithm is written from scratch, with no third-party library, as the brief required
The input is validated
Hidden tip: when a split leaves single-value intervals (like 21 - 21) they get an animated outline, and two or more are joined by a bracket labelled "Magic ranges"

Stack: React, TypeScript, Redux Toolkit, Jest, React Testing Library, Vercel.
