I work as a database and smart contract architect for FinTek Development. I am also a published tech writer and video instructor; one of which is my YouTube channel SQL In Six Minutes.
In the more than seven combined years I've worked in tech, the largest opportunity I've seen - whether for a freelancer or potential business owner interested in data - is the opportunity to automate data and build a structure which acts on these data. From hospitals to colleges, few, if any, organization does this well and students who take this course will have obtained the experience that many people learn over the course of a decade or more.
Finally, I am a proponent of the learn-by-doing methodology. I've worked with and interviewed many individuals who had too much theory, often from higher educational institutions, and too little practice. Since tech changes rapidly, people interested in tech must show a willingness to practice often and learn quickly from their practice.
