I've been a System Administrator and full stack developer for over 10 years, the typical profile for a DevOps engineer. I've been working in multiple organizations and startups. I've cofounded a startup that focusses on applying DevOps and Cloud. I have been training people in newer technologies, like Big Data. I've trained a lot of people working in FTSE 100 & S&P 100 companies. Today I mainly work together with companies to improve their software delivery processes, while coaching and teaching on platforms like Udemy.
