Trainer at Linux Weekend Learning
I have been working on Linux for more than 7 years. I have seen many people still lack their skills on Linux. So, i am working on courses for Linux which will make them Learn Linux in an easy way. The agenda of my courses will be more practical and less theoretical. Show more examples and you will easily grab the concepts.
