Who I am: - A manager of one. - A big fan of the 80/20 rule. - I believe in the Ruby renaissance. My strengths: - I can clean up legacy code that others are afraid to touch. - I can write a project from scratch. I know how to work with Ruby without Rails. - I enjoy reducing infrastructure costs; optimization isn't limited to fixing n+1 queries. - I love improving DX; automation and short feedback loops are everything to me.
