Alex Karasulu is an entrepreneur with over 25 years of experience in the software industry and a recognized leader in the open source community. He is widely known as the original author of the Apache Directory Server, used by IBM both as the foundation of the Rational Directory Server and also integrated into the Websphere Application Server. Alex co-founded several Apache projects, including MINA, Felix and Karaf, among others, which, along with their communities, thrive independently past his day-to-day involvement in the projects. He is the founder of Safehaus, where he authored the first low-resource mobile OTP algorithms in open source with the OATH community that was later adopted by Google in their Authenticator product. In addition to IBM, Atlassian, Cisco, and Polycom are just a few of the many companies that sell commercial hardware and software solutions that bundle or embed software and products that Alex has created. Alex holds a BSc. in Computer Science and Physics from Columbia University.
