Swiggy/Zomato Low Level System Design | Whiteboard explanation, UML, Code in Detail

[@kishorepurswani1212]

Congratulations Keerti! Whenever you create a video - even seenagers like me can learn something. Proud of you ♥♥♥

[@Sasikumar-kr7xy]

I can see the how well the preparation was , the way its being carried throught out the video and the amount of work done to make it understandable. Kudos Keerti !!! :)

[@KeertiPurswani]

Thank you so much! Please do show your support by sharing the content with your friends 😇

[@sreeharshagarimella1593]

Class !!!! People should appreciate the deep worked need to pull off a video of this kind. Hats off

[@kyayaaromkar]

Huge respect to you ma'am for the efforts you put into creating these lectures. These detailed UMLs and then the implementations. You can rarely expect all of these at a single place. I am more impressed on how you've been implementing these in Cpp. Thank you so much!

[@rishiraj2548]

very nice tee, and excellent venture. 06:45

[@mouneshdb9211]

I watched so many videos regarding system design no one explained detailly like you i like the way you explain even beginners can understand how things will happen in the background Thank you so much and I'm waiting for more content like this 🎉❤

[@asmitamishra4965]

Congrats Keerti ! for coming up with an excellent educative video

[@aviralgupta9869]

I can say for sure creating a video like this would have taken a lot of efforts for sure !!. You got a new subscriber :)

[@barishkhandelwal8757]

can you please start the video with mentioning the requirements first before directly going into classes like Food Mgr,etc. It would be great to give 5 mins to go through requirements. It would help in understanding what all functionalities you are going to cover in your design

[@gulnazshamsi981]

Tq mam for making so useful videos like Faraz sir and Nishant sir

[@hydtechietalks3607]

Thank you Keerti for your efforts.. Please do give these code hubs in terms of MicroServices, that helps new generations... and also Challenges you discuss gives more AUTHENTICITY and POPULARITY instead of usual routine flips... All the best!

[@umadasari7339]

Loving the Content 🥰

[@VinayListenMe]

You should first give a high level overview of users of any system before going to deep dive technical, like:- 1 normal user who orders 2 restaurant admin 3 System admin Then you can touch the each component accordingly...very nice explanation though.

[@shaikhanuman8012]

Thanks for providing always good content on low level design.

[@piyushkumar-bl2ck]

What about pricing? I believe it should be determined using strategy pattern in OrderManager itself. Others can share their input.

[@tle964]

Nice Video, One feedback, you could divide big functions into smaller function and also could have make classes inside relevant packages for more readability

[@user-gt1me5mg3k]

Nice Explanation, really insighful

[@PS-ne2rp]

Nice video keerti

[@rahulrahul-cm4mn]

Excellent video

I love her ❤❤❤

[@saravna]

In my view Dish and Dish Addon will not be a composition. Since one addon can be used in multiple dishes. What do you think?

[@sraynitjsr]

This is the trailer of the movie I'm eagerly waiting for that's coming up soon, LLD COURSE 🔥

[@KeertiPurswani]

I am sure we will have a great time together ✌🏻✌🏻😇😇

[@anjalisoni5945]

Ma'am I want to know which tool you re using to make UML diagramme

[@vivekgujari9118]

Hey Keerthi, can you please help me understand how we are injecting RestaurantMgr dependency in FoodMgr? Maybe I missed something here.

[@tanujarora4906]

I need this level of confidence in my lld skills to not bomb these rounds again and again 🗿💀

[@MaxTechKnowledge]

Dish Add on can also be decorator right ?

[@DevSoni-yy7th]

Cold drinks can not be treated as Dish as you can not order only cold drinks , I dont think so swiggy will deliver cold drink only, keep it as addon

[@abhilashbandi3866]

Started watching video. Needed that Tee-Shirt Keerti. Good time to start selling swag?

[@KeertiPurswani]

Already started!!! You can get it at www.theliteratestore.com !!! Hope you will like ✌🏻✌🏻 Let me know 😇

Kafi solid 💀

[@karthiktechhunter1145]

I really loved your idea & swag of the literatestore, but there is one issue for me. I really loved the light green color hoodie of rm -rf /life, but it's only available in purple color. Please make it available for light green "rm -rf /life" as you wore in the video "Why i left atlassian", i loved the hoodie and in obsession with this after watching "Why i left atlassian" Video.

[@KeertiPurswani]

Hey! As a new business, we can keep designs in limited colors for now but if you show us your support now, we will make sure that we provide as many options as possible. For now, if you really want that particular color only, please mail your details like size - we will see if it’s possible to send you a custom made one!

[@karthiktechhunter1145]

@@KeertiPurswani Sure where should I send the details, please let me know!! Thank you for responding, i am really blessed with your presence!! I will always support you and show my support 100%. Please continue, and don't stop!!

Do we have to write all of that code in the interview?

[@premmane9816]

Aap java use nhi karte ho kya 😅

[@codewithjayminn]

Thank you ma'am for this video. You know why I linked KZbin video rather than college lecture because there is no other talks not related to study. Just focus on topic

[@KeertiPurswani]

Please do share it with your friends as well ❤️😇

[@tejasvishnu3836]

i am curious about the notification part which i am stuck before in creating delivery apps

[@salman1098]

You are stuck on notification part?

[@shivaarukonda2640]

Ma'am, in interviews do they ask for end-to-end working code?

[@KeertiPurswani]

Yes! Obviously not of entire system, but you are expected to write code for a subsystem and preferably use design pattern and explain it in detail.

[@shivaarukonda2640]

@KeertiPurswani ma'am, I can draw uml diagrams. I can code classes, interfaces with attributes and methods, and I can map with relationships among them. I can able to explain the use of design patterns in the required areas. But as of now, I can't able to finish end to end workable code .

[@KeertiPurswani]

@shivaarukonda2640 it will come with practice! When you draw UML diagram, try to visualise end to end system then itself. Converting UML to code is very easy then.

[@darshanbs2267]

Came 1 day before interview and felt it was a mountain 😢

[@thesoftwareengineer17]

what is this mtx : Mutex ? can someone help me understand

[@aniketkatakdhond9310]

It is a lock mechanism provided. Basically in singleton design pattern we want only one instance of class to be created. Multiple threads will create many diff instances and so inconsistency in data. So mutex lock prevents that from happening.

[@DevfestCoder]

Hey @Keerti please make your wesite Url clickable for user engagement on your site 😅

[@KeertiPurswani]

Sorry what? Where?

One suggestion - make HLD video live as membership videos over youtube.

Hey, you can enroll on the site for the same - www.keertipurswanicourses.com
