• Harald Lazardzig

    CTO / Online Entrepreneur

    Hi, my name is Harald Lazardzig. Coding since the late eighties, I'm on the Internet since 1991, installed and configured my first web server in 1993, wrote a book on Unix in 1994, used to be an academic in what feels like a previous life, whereas now I'm an Internet Startup manager, a CTO, and somehow still a full stack web developer, specializing in Internet Startups and Online Media. Currently I work as an IT-Consultant and Business Angel, mostly at my own company, Übungssache GmbH. I love learning (not least from my mistakes), working with intelligent people and discussing what I've learned with them. This is a private website, automatically generated from my LinkedIn profile with the help of strikingly.com, and here you can find more about me and maybe get in touch for a chat about potential projects.
