My name is Alejandro Gallo and I am currently a physicist at the Technical University of Vienna https://cqc.itp.tuwien.ac.at.

I work in the interface between condensed matter physics, quantum chemistry and software engineering.

I am the author of several scientific packages like CC4S, my personal SISI4S and a high-performance kernel for the CCSD(T) algorithm ATRIP with on-going CUDA support.

I enjoy building many things, be it on the computer or with my hands. Maybe check out my github profile for some examples here.

• I am the main author and maintainer of papis.
• I try to optimize my keyboard layout in the split keyboard lab. and the QMK לוח keymap.
• I build my own dictionaries for hebrew and arabic.

• I had much fun playing in Baasztian's album diagnose: chronisch ironisch.
• I released a demo back in 2006 called Open 24 Hours under the artistic name of Nango, you can check out the bandcamp here.
