About
I am Juan de Dios López, a computer systems engineer from Instituto Tecnológico de Pachuca. I started in the public sector automating paperwork, moved through analytics, and ended up where I am now: building web and mobile products, and leading small front-end teams.
What interests me most is the point where an application stops feeling slow. Refactoring until load time is cut in half is unglamorous work that completely changes how a product is perceived.
