Skills Heat

The landscape of tech job skills is shifting at a dizzying rate. This tool uses data from the Dice job site to show which skills are heating up from demand outstripping supply - and which are going the other way.

Si came up with a brilliant succinct clean way of visualizing that dynamics while tackling the challenge of way too many skills cluttering the screen.

We at the Data Science team had the need to represent tech skill supply vs demand to provide a glimpse into which skills are hot, which have fallen out of popularity, on some sort of relative scale. Si came up with a brilliant succinct clean way of visualizing that dynamics while tackling the challenge of way too many skills cluttering the screen. One can clearly see the entire landscape and zoom in on particular skills or groups of skills. In addition, trend information is readily available in the form of line charts. This visualization shows how a big volume of data points can be exposed in an elegant comprehensible way on one single page.

It was really delightful to work with Simon as he was highly professional, respectful and really responsive to our feedback throughout the process...

Simon kindly helped Refugee Rights Europe in 2017 with a visualisation of our field research data relating to refugee children in Europe, on a pro bono basis. It was really delightful to work with Simon as he was highly professional, respectful and really responsive to our feedback throughout the process. Even though this was a pro bono project, he worked in a timely manner and ensured effective communication with our team. The final product was fantastic, and it really helped us tell the story of some terrible predicaments which refugee children in Europe face, so that we could better communicate our message and influence policy and practice for the better.
