Henri Aunin

Student, frontend web developer and Linux sysadmin based in Tallinn, Estonia.


Mainly my expertise is in frontend web development. I sometimes tinker with Linux, open-source software and servers. I am keen on learning new technology or on how old technology can still suit us better even today.

Sometimes I write in my blog about whatever pseudo-intellectual nonsense I have on my mind — mostly nerdy technological ramblings but could extend to a discussion into random personal topics. I'm also quite interested in internet privacy, self-hosting and web decentralisation.

Find me on Mastodon, Github or send me an e-mail to [email protected] (GPG).
