Swizec Teller

A geek with a hat.

Hi, I’m a digital nomad and full stack web engineer.

I travel the world and help startups win. From setting up new teams and training juniors, to fixing spaghetti code and implementing new features.

My code has been used by MasterCard, Commerzbank, Google, Mashable, Lyft, and many others.

When I’m not coding, I’m writing.

At least 5000 people bought my books ... I don’t know if that’s a lot, but it’s more than zero. I like that.

My work has been featured in Business Insider, LifeHacker, Huffington Post, and several dead-tree magazines. I’ve spoken on BBC Radio, appeared on Slovenian national television, and given talks all over the world.

My Books

Why programmers work at night
Why programmers work at night

The early bird does not always catch the worm, sometimes it meets a cat.

Programmers often work on unusual schedules that do not jive with the modern 9-5 office culture. They don't even do their best work at offices.

This book shows programmers and those around them that there's a better way.

"My girlfriend loved your book!" ~ Jan Hančič

Data Visualization with d3.js

When you're learning d3.js on your own you often feel like Step 1: Draw two circles, is followed by Step 2: Draw the rest of the owl. My book aims to bridge that gap.

I guide you through complete examples from basic shapes on a page to full blown visualisations. There is no magic here, no steps left unexplained. You will understand everything that goes into making a visualization with d3.js.

React+d3.js
React+d3.js

Creating dynamic data visualizations on the web is a pain in the ass.

You either have to use dumbed down libraries that won't let you do what you want, or make everything from scratch. Every time.

You want a quick way to build complex visualizations. Build once, use everywhere. In every project. Don't believe me? Scroll down.

With React+d3.js you'll learn how to build re-usable visualization components in about an hour.
