Back when I was a teenager, there were two things I was absolutely sure of: one, that I loved writing software, and two, that I was gay. But it wasn't easy growing up gay in the city of Belfast, so at the age of 18 I left Ireland and moved to London. I thought that my problems were behind me but in reality they were only just beginning. I was ignorant of the trials and tribulations that I was about to face. This talk offers advice for gay men and members of other marginalized groups on how to build a successful and happy professional life within the tech industry, based on my own experiences and those of others that I've met during my career.
