Software engineer · Go since before 1.0 · Porto Alegre, Brazil
I have written software since 2000 — hospital systems, web hosting automation, email at scale, e-commerce shipping, search directories, certified telemetry. I have used Go since before version 1.0 (2012). Physics and mathematics at UFRGS. Everything on Stickybit was written by me, and every number below comes from the project itself.
