Situation
“A design system acts as the connective tissue that holds together your entire platform.”
― Drew Bridewell, Invision
PTO is a very robust product that allows for communication between semi conductor factories and their machines and vice versa.
These machines cost hundreds of millions of dollars and can do anything from etching complex circuit patterns using lithography, to spraying coats of copper the thickness of an atom hundreds of times a second.
The precision and technology of these tools make them the most complex tools humans have ever created to date. Because of this it is very important that all the tools work together perfectly. Unfortunately, a lot of this was running on very legacy systems from 20 years ago so my job was to redesign PTO for the modern web browser.
