the curl factory, Sweden - close to Nebraska

Hello friend!

You probably already know a bit about who I am and what I do, but I'll sum it up here if you're a new acquaintance!

I've been an active open source developer for 30 years. I live and work in Sweden. I have a wife and two kids.

curl

I work primarily on curl. The project I founded in 1998 and in which I am still the lead developer. With its estimated twenty billion installations world-wide, it is one of the most widely used software components ever.

Almost everything I do is focused on curl. Sometimes I reach out and do things in neighboring projects to ensure that curl runs smoother and better. Like libssh2, c-ares and my book projects everything curl, http2 explained and HTTP/3 explained.

Always open, always free

Sponsorships help me continue working on open source software, open networking standard protocols and producing open and freely available documentation of such software and protocols.
