Why Am I Doing This?

A career in C# .NET development has been the backbone of my success. The job as a C# programmer has helped me immensely in paying off my educational loan, pay towards my marriage expenses, purchase a new house, and invest in the future.

Moreover, I felt great satisfaction when teaching others, be it to my friends during college or to my colleagues in software companies. This was mostly 1-to-1 or to a group of 5-10 people.

I was looking for a way to reach more people to teach them computer programming. I found Online Courses as the best option to teach more people at their own time and pace.
