Talentefinder is the number 1 match making application for career events. Recruiters and talents can use the match making interface to find the perfect career opportunity and the class' best talents.

In 2021 the application held over 100 events with more than 35000 talents. As the frontend developer of this team, I ensure that the application runs smoothly and that new features are implemented effectively. Some of my proudest achievements include: implementing localisation, implementing updated brand identity, developing the job platform with payment subscription and much more.

DHI GRAS - Development

React, Mapbox

Design, web development

Between 2018 and 2020, I have been working at DHI Gras where I was responsible for almost all digital output.

The web development focussed on online data viewers and portals through which we raised awareness for our products and projects. I streamlined the design, implemented a mobile-friendliness focus and improved the techstack to include the most modern frontend frameworks.

It resulted in over 2 dozen viewers and new ways of sharing and promoting our work.

DHI GRAS - Design

Wordpress, Elementor, After Effects

Design, motion animation

During my time at DHI GRAS, I was responsible for defining a graphic style and increasing the organisation’s online presence.

This required us to esteblish a online brand identity and a streamlined tone for communication. It resulted in a new DHI GRAS website developed in Wordpress with Elementor, and dozens of SoMe videos that have gained significant online attention.
