After a long career in the hospitality sector, Alessandro discovered The Information Lab thanks to a demonstration carried out at the University of West London, where he graduated in hospitality management. Alessandro was positively impressed by the hiring process of The Information Lab, which was based on the creation of a project rather than being tied with CV’s.

Since then Alessandro has pursued a career change towards data visualisation. Applying to the Data School was his first real attempt in this direction. The teaching and placements activities seem perfect to provide Alessandro with a solid foundation to successfully begin his career change path.

Second Client Project, First Imposter Syndrome Case

Last week I wrote a blog post in which I explained the work that my fellow DSers and I have carried out for our first client project at the Data School. This week, instead I will focus on the difficulties I have encountered during our second client project and how these reflected in my actual presentation.

DS13’s First Client Project

Last Friday, I and my fellows DSers presented our first client project since the beginning of our studies. So far, every Friday, we had the opportunity to watch DS12 client project presentations, while we would produce a presentation based on some data provided by our coaches, but not linked to any specific client. Hence, this represented an important milestone for our cohort, from now on this will become our weekly routine.

Project Week 4 – Table Calculations in Alteryx

Last Friday’s project challenged us to practice the two main topics covered during week 4, Table Calculation in Tableau and Macros in Alteryx.
The task aim was to reproduce as many table calculations as possible in Alteryx, transforming them in dynamic macros.
In this post, I would like to show the calculations I’ve managed to reproduce in the time span of 4 hours.

Week 3 Project Public Trade Companies Stocks

Data Preparation… for Dummies

Last Friday DS13 was assigned a project. In the time span of 2 hours (which became 4 afterwards), we had to re-create our application viz. It was also required to find a new dataset, preparing it with Alteryx or Tableau Prep, and adding it to the original Viz. In this post, I would like to describe how I used to clean up the data before joining DS and how this process can be streamlined using a tool such as Alteryx or Tableau Prep.

Data Visualisation… using crayons?

At the beginning of this week, Andy informed us that an upcoming session was composed of over 200 slides. Due to this all I was expecting was a long theoretical session, instead, Andy gave us some crayons and large paper canvasses.

My application Viz: Pokémon, a guide to beginners.

The first Viz I’ve published on Tableau Public, Pokémon: A Guide to Beginners, was a great, and unexpected, success.
In this post, I would like to describe the first step of the Data School application process, focusing on the techniques I have used to build such a successful Viz, which guaranteed me the access to the next stage of the process.
