Personio is one of the fastest-growing modern all-in-one HR solutions specially made for SMEs.

On this project, I acted as a senior front-end developer for a design system team where I was engaged in creating new and optimizing existing component libraries. Part of the engagement was consulting and collaborating with the whole team (designers, developers, leads) and suggesting improvements or possible edge-case problems that must be overcome. Solutions with the best approach to spend the least time were the main focus, as fast-growing requirements from other teams were always present.

While working on my primary task, I also supported other teams with faster and preferable implementation of design system component libraries while maintaining and suggesting the implementation of design guidelines.
