Hi! My name is Taavi (he/him).

I am a site reliability engineer, and professionally I'm currently working on the Wikimedia Cloud Services platform.

As a volunteer I maintain many authentication and security-related MediaWiki extensions, including CentralAuth which powers the Wikimedia single user login system. I was granted commit ("+2") access to MediaWiki core in 2021 and in August 2022 I was awarded the Wikimedia Tech Contributor of the Year award.

In addition I'm involved in the Debian project, and I maintain the Debian packages for MediaWiki and other software. I became a full member of the project (Debian Developer) in May 2024.

Most of my miscellaneous personal projects are available on sr.ht, and some older projects are still on hosted GitHub.


My latest blog posts are:

If you use PGP, my key is 3465 469C B19D 61E5 E2EA 8AFB EF24 2F70 9F91 2FBE, which is available from taavi.wtf/pubkey.asc and common keyservers such as keys.openpgp.org, keyserver.ubuntu.com and keyring.debian.org. (Ok, the last one is maybe not so common.)



This website is built using Hugo. It features a custom build of the Iosevka font. The source code is hosted on sr.ht, and the built site is deployed on infrastructure powered by Debian, Apache HTTPd and HAProxy.

It uses zero JavaScript and just a couple of kilobytes of CSS styles. Most of the page size currently comes to the custom font, which takes about 25kb to fully load, even with most unnecessary characters removed.
