Howdy! I’m Mat, _{(an aspiring engineer focused on open protocols, embedded systems, and rapid prototyping^[1].)}

:where to find^[2] me

a lil' `:about` me

A decade of technical experience has shaped me into an indie maker who builds engaging, accessible, and secure tools^[3] for real people. I am especially passionate about search UX, decentralized infrastructure, and a safer internet.

Outside of computing, I’m also a guitarist, competition aficionado^[4], and linguaphile._{(English, Spanish, and Esperanto)}

	README 88x31s?!
competitive environments fostered my "ship early" mentality↩ i normally go by `@matmanna` (or `@mat`) but please verify ↩ i see my projects as tools meant to serve (what do i use ↩?) esp. trivia, having competed on a TV quizbowl and won 3^rd at a regional NOSB.↩
