How's It Going?

I'm Henry Haefliger.

Software Developer, Data Scientist, Writer

Dear Visitors,

I am so glad to have you here!

Let me begin by introducing myself. I was born in April 2003 in Geneva, Switzerland. My mother is American and my father is Swiss.

In 2010, I was fortunate enough to have the opportunity to move to Shanghai, China, where I lived until 2017. It is also here that I met Mr. Cressey, my math and computer science teacher in sixth grade, who led me to fall in love with technology.

I have always had a passion for understanding and building things, but this is where my journey with computers began...

It has been a while since 2014, and we have all probably come a long way in the last few years. I personally have had countless opportunities to break things, experiment, learn and create.

I have not, however, diminished in my curiosity. Some of my projects are scattered around the place or seem somewhat janky, but this is merely a symptom of exploration and I look forward to continuing this relentlessly, wherever it may lead.

There is an infinite number of people who have helped me to arrive where I am today. I have tried my best to compile a non-comprehensive list here.

If you are interested in talking to me, you can do so using this form.

Best Regards,

Henry Haefliger
