about!

Hi there! I’m Alex. I go by dari online (or qcoral depending on where you found me). I’m a 20-year old from Toronto who’s been making projects on and off for the past ~10 years!

I’m currently focused on building out the open-source hardware community I wish I had as a kid growing up @ Hack Club! I also study math & physics @ University of Toronto.

Want to hang out? Find me at:

In the past, I designed my own 3D printer from scratch (that fits in a filament box!), ran a 4-day hardware hackathon at GitHub HQ, and also played Overwatch semi-professionally. (and also did origami. and chess. and sold keyboards. and some other random adventures)

The next event I’m attending will be: RMRRF 2026

If you ever see me in public, please say hi! You might just [get something cool from me]

Explore my various adventures:

[gap year at Hack Club (WIP)] - [e-sports & competitive gaming (WIP)]
[events & cons I’ve been to] - [more coming soon!]

I’ve been on this planet for 20 years! Here’s some of the stuff I have cobbled together in the meantime:

  • Neutrino, a $200 USD printer that fits in a filament box!
  • more coming soon!
