Quantified Self

What were you doing on July 27, 2013 or December 18, 2008? What was your heart rate? What did you eat? How did you feel? These are questions I'm answering using my Quantified Self dashboards: a series of dashboards covering finances, exercise, health, psychology and other things to keep track of me. A helpful way to notice trends in behaviour and to work on the machine that is me. I'm hoping to move all of this data into mongoDB or mySQL to make this into an app, but for now Excel serves as the project's data store.

Sample Data: Spending on biscuits over 15 years in ZAR


Book, TV & Film reviews


Exercise sets


Transactions recorded


Some visual coding done on Android using the Automate app, which allows you to create apps that respond to inputs on your phone. The applet I created below runs a daily review at a set time and collects all the information shown below and weather and air quality (both from APIs). This information is stored in a CSV and then sucked into the one of the dashboards mentioned in the Quantified Self section of the projects page.

LookBook 2018

A short look and feel for some of the styles, looks, materials and combinations that were inspiring me in this year. I didn't get to build many of them in real-life, but snippets here and there exist in my now rarely used wardrobe (thank you pandemic!).

Over the past 15 years I've been keeping managing my finances using various methods. In the last three years I switched to using Excel as one of my projects to do this, because an app I liked had stopped being maintained. I created a spreadsheet that records daily transactions, tracks investments, manages debt and has an asset register. All of this is summarised neatly in the dashboard. This gives me information to help manage my finances; right down to niche data like how much I'm paying for fruits and vegetables per kilogram for any period.


This website (and the other web apps I run) has existed in different forms for over a decade. The latest reformat happened in 2020 and involved more custom development: from a custom must-use plugin to deep customisation of WordPress, Woocommerce and Elementor. These projects are ongoing and I hope to keep this skin for at least a couple of years.

The island of Réunion offers everything - beach, mountain, volcano, jungle and city - in an area small enough to drive through in a single day. These are few pictures from a trip I took that bountiful place.

Behind the Numbers series

I designed and typeset two books in the Behind the Numbers series. A look at some gruesome history from the Apartheid years. The books are for sale on the writer's website.
