Hi, I'm João.
I studied physics and informatics, and I like building things, understanding complicated systems, and following interesting problems wherever they lead.
This is my corner of the internet — part notebook, part portfolio, part excuse to keep tinkering.

Into
Music, and DJing whenever I get the chance.
