tazjin's interblag

Hi, I'm tazjin.

I spend a lot of my time hacking on the TVL monorepo and doing other computer-related things. Follow me on Telegram, via the feed here or (occasionally) catch me in-person at undef.club.

Below is a collection of my projects, blog posts and some random things by me or others. If you'd like to get in touch about anything, send me a mail at mail@[this domain] or ping me on IRC.

@tazlog on Telegram

My new channel on Telegram, for occasional updates smaller (and more frequent) than what ends up being posted here.
