Robert "r0ml" Lefkowitz is the Chief Architect at Warby Parker, a technology-enabled lifestyle brand. In 2015, Fast Company named Warby Parker the most innovative company in the world.

Prior to Warby Parker, r0ml worked mostly in the financial and telecommunications industries, acting as Chief Architect at AT&T Wireless and Vice President of Data Services at Asurion and Morgan Stanley. In 2006 he was named a Distinguished Engineer of the ACM.

At one of his first seven jobs, r0ml was the Public Software Librarian for a timesharing company -- seven years before the GNU manifesto. In 2000, he became the first person at Merrill Lynch to install Linux, and as a result, his computer was confiscated by the IT department. In response, he became the Director of Open Source Strategy for Merrill Lynch, and secured the email address r@ml.com. He regrets the loss of that address.

r0ml is an enthusiastic, albeit not very accomplished, fencer and juggler, and enjoys studying obscure programming languages. He grew up in Brazil, with a French mother and Chinese father of Russian ancestry. He would love to say something about his wife, Gina, and their seven children, but space does not permit.
