I am a trained Robotics engineer, a professional hacker, a stand up comedian and an entrepreneur. I’ve hacked Salesforce, Slack, Servicenow, Dropbox, Google and have been recognized for it. I’ve run an agency for 15 years and founded it just when the global financial crisis was unleashing on the financial markets. As an engineer, I’ve been trained to solve problems using experimentation. As a hacker, I often write tools that help others solve problems. As an entrepreneur, I have survived two global recessions and have put up steady growth in our business every year.
