Hello guys!
Quick question. Would you like anymore videos on Big Data, Data Science or any other topics?
Please let me know. I'm focussed more on CSS tutorials right now.

Thank you for your VERY clear and eloquent presentation. You have a VERY well-organized flow of conceptual logic, and clearly representative of depth of your knowledge. I have subscribed with the hope that you add to your videos, take your viewers to a journey of exploration of the recent advances in DB theory and implementation. Certainly it is a long journey when ordinary lecture series take on the task. I am certain you will invent a most efficient, yet rigorous road to this goal. My gratitude and admiration.
