@TechLead

Please "like" the video to support my technical content, and I will be happy to make more for you 👍 I'll do one for mobile systems design if we can hit 5,000 likes.

@bin4ry_d3struct0r

This is definitely one of the more useful vids for techies on this channel. This guy isn't just boasting about being a tech lead. He really is the TechLead.

@justinv3512

The TechLead ran out of trolling/sarcastic video ideas, so The TechLead actually put out useful content that he learned from being an Ex-Google, Ex-Facebook Engineer (as a Millionaire).

@domibr4966

I don't even know the least bit about computer science or IT. I just love to listen to the Tech Lead.

@willdedill

The BEST TechLead video I ever watched hands down, you see he didn’t mention a single second that he’s an ex-Google ex-Facebook whatever, nor talking about his wife. 
Straight to the point, thank yoi for breaking this concept to us 😅

@akai2112123

The database replication with slave and master and  sharding! splitting the tables vertically and horizontally blew my mind like wow ! ps: I am just 2 years into dev so I found all of these concepts very intriguing and exciting!

@cam41527

This is like one of the old Tech Lead videos that got me to subscribe in the first place! I love these type of technical topics, keep them coming! :D

@neerajkulkarni6506

Still one of the best and most concise explanation of key system design concepts on YouTube!

@chevalier5691

I can't believe this video exists. This man will singlehandedly helped me and others land a job even 5-10 years from now. I have no experience about scalability because my projects have never needed that much, but now I can atleast understand some terminology that would help a lot in system design interviews.

@icebox747

This is the reason why I started following TechLead a year ago, , thanks for bringing it back. Love your explanation alot!

@stevenmccarther5836

In Boot Camp and a relative suggested I review this video.  Very much appreciated.

@ByteMock

System Design questions are challenging to prep for. It is a great way to show off your problem-solving ability and personality when compared to whiteboard questions.

@fredwu6812

Techlead, this is the time that you are showing us how much power you have.  Holy shit!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!  I think even my university professors cannot even compete with you.

@TheSvs1

Those types of videos proves that he is the Real Tech Lead (as a millionaire and an ex Google & Facebook);

@NicolaAmadio

this is one of the best videos he's put out
