When we say tech, what do you first think of? Young men squirreling away in a dark room surrounded by half eaten pizzas, lit only by flickering lines of code – an army of wannabe Mark Zuckerburgs on a mission to develop the newest product which will make them millions? Or a woman? For the majority of us, the first image springs to mind – sort of understandably. After peaking in 1991 at 36 percent, the number of women in computing roles has decreased to 25 %. Gender ratios are as low as 1 female to every 4 male engineers in top tech companies like Google.
