So glad that I signed up for this course. Arpit has a very well curated topics which he covers in depth. From small nuances to big design decisions. This course has helped me move away from a developer mindset and look at systems at a holistic picture. I can now relate to the designs of so many systems I helped in developing.

This is the best cohort course when you want to understand how systems are actually designed and built. The course is designed in such a way that you will never feel this is beyond your grasp.

Every system starts with a naive architecture and you will be amazed to see the end system after discussing all tradeoffs. If you can’t relate to this course now, You will definitely find this course helpful somewhere in your career.

On a personal note, I was being introduced to several jargons and components which play a key role in Designing the systems. You are doing a Fab Job Arpit! Thanks a ton :)

“Your enthusiasm is contagious” - a fellow student said to Arpit on our last day of the cohort, and I couldn’t agree more.

• It goes beyond what’s just needed for interviews and tries to address difficult design choice questions

• The classes are well organised: They aren’t just a unidirectional flow of information. The students get to participate in brainstorming the problem statement, building them from scratch, and Arpit ensures to nudge us just enough to keep us on track, and more often than not, the students themselves only are able to come up with quite similar approach as Arpit later discusses. This is a really good quality of a teacher: not giving away the answer, but at the same time, making the students capable enough to arrive at the answers by themselves.

• No class ends with a student having some doubt: At the end of each class, there is an open discussion, where all doubts related to the topics discussed are clarified, and then only the class is concluded.

• What makes Arpit stand out from other instructors out there is that most of the content discussed in the classes, Arpit had first hand experience building similar systems in production. So, he is teaching from his practical experience.

• Recently, he announced system design video library: All the best discussions for each problem statement would be updated here and all the new problem statements covered in the future batches will also be made available to all the students who had enrolled in any cohort. Life-long learning, what else can one ask for

• One major learning was: We always think too ahead and complicate things. Repeatedly throughout the course, just how starting simple and iterating over it with common sense leads to good robust designs instills a lot of confidence in students, making them realise designing system is no rocket science, its just taking one step at a time, and being aware of the already available solutions out there and building on top of them.

• And finally, like I mentioned in the beginning, apart from just the content of the course, there’s a lot more to it: I’ll highly recommend another fellow engineer just to be part of the discussions: the enthusiasm with which Arpit discusses in all the classes is something to witness. It takes you back to the point of thinking why all of us got started with software engineering in the first place: to get the sheer joy of building things. Down the line, its very normal to lose motivation or not feel as enthusiastic as we were when we were fresh out of college. Its really one of an experience to witness Arpit’s enthusiasm in all these classes, how he has sustained it for so long over these years, and if you look closer, it’ll tell you the BTS of making of a great engineer, what sets a great engineer apart from others: because of their ability to find pleasure and being hungry for more always.

I can only say that taking this course has been a really great decision. It has far exceeded my expectations. I’ve never seen anything on system designs that goes this deep into talking the ‘what’ ‘why’ & ‘how’. What makes this cohort even better is that it’s not your classical ‘watch your instructor’ instead it’s more inclusive you’ll have all your doubts answered.

Great learning experience. Absolutely worth it.. Loved the content and brainstorming sessions.. I would definitely recommend it.

I almost envy Arpit. Not because of his financial success, (there are many financial successes out there for one to get envious) but because he is so in joy when he talks, teaches and brainstorms system design. Kind of like the Ikigai. Anyways thanks a tonne for explaining system design so beautifully 🙏

Arpit’s cohort is the answer for everyone who want to genuinely learn(or grow their knowledge of) how to design highly scalable & resilient systems, not just how to crack system design interviews.

Arpits’s approach of problem solving, starting from the ground up, asking “WHY” for every design choice, big or small. Arpit makes you think of that one remote performance improvement scenario and it’s this attention to detail, that makes Arpit’s cohort truly unique and informative.

Couple the above with the cohort’s diverse thought processes and experiences, and you get yourself a fabulous learning environment. I cannot remember one session post which I didn’t have any new takeaways/learnings.

The cohort has been the best part about my weekends, and I definitely recommend it to everyone!

What you get - Amazing Mentor, Great discussions/Brainstorming sessions & #AsliEngineering concepts!

This course is certainly the best for anyone who wants to go in-depth on the High-level design of multiple scalable architectures in different domains.

I had done one-on-one with Arpit and come to know that this guy is really passionate about learning new stuff in the depth and finds real joy in teaching other people this amazing stuff. His funda is “Ek hi zindigi hai, seekh lo jitna seekh sakte ho”. He regularly reads research papers to go in-depth just so that he can understand and make others understand.

Coming back to the course, since a lot of iterations have already happened over the past 1 year and I have also attended the March-April cohort, I can ensure you that you won’t go empty-handed no matter how much experience you have. You will definitely get to know the behind the scene working of some of the amazing systems. For me certainly, this is one of the best investments on myself in the past 2-3 years.

Undoubtedly one of the best educational content! Arpit’s love towards system design is infectious. One will definitely fall in love with system design after his cohort. He makes complex concepts look very easy with his good analogies which will make core concepts stick to mind for long time.

Thanks Arpit for doing such great job! Definitely blockbuster movie for system design must attend 😊😊😊

Thanks for the amazing course. The amount of depth and breadth you are going into for each problem statement is just mind-blowing. You are a real inspiration and a true gem. Thankyou very much for spreading the knowledge. The cohort-based structure of the course really helps.

It was amazing to see how each and every time you align the thoughts of all the participants into the most ideal solution. Learned many new concepts during the last 2 months. Wishing you and your family all the very best!!!

I would recommend this course to everyone who are still looking out for mentors who can teach how amazing engineering is. I joined this course not from an interview perspective but i wanted to know the bigger picture on how different systems are scaled to a million users, and definitely i got to learn a lot.

I can confidently say Arpit’s approach to teach system design is exceptional, you cannot find this kind of content on any youtube video or MOOCS. Personally, this has been an inspirational 2 months for me where I got to know exactly how we can approach engineering problems and what resources to go through to brush our skills. His passion for engineering is contagious and if you want to know Asli engineering inside out then this is a must join cohort.

This course was the highlight of my weekends for the past two months. I’ve been exploring system design content for quite some time and after going through a lot of content, I must say Arpit does full justice to the time people invest in his course. Arpit does not shy about going to a detailed analysis of any system, he makes sure that every possible doubt that comes into your mind is resolved during the session and later in the open forum session. I found this very useful as Arpit’s extensive background in industry and academia gives him the ability to go as in-depth as you want when answering your questions. Be it databases’ internal implementation, operating system quirks or hardcore computer architecture question, Arpit knows his stuff really well.

Small cohort size and interactive brainstorming sessions helped me to get quick feedback on my design decisions. This made sure that the session was not just a one-sided lecture but an exchange of ideas amongst the peers. The cohort had people form different domains and varying experience - I used to search for the technologies and jargons people floated in the discussion which gave me an amazing exposure.

Initially, I joined this course to become comfortable in system design interviews but later I realised that the main intention of the course is core engineering and detailed analysis of systems, which you might miss if you’re simply studying system design for interview purposes. Cracking interviews is a favourable byproduct of this course and not the sole intention. Thanks Arpit, I thoroughly enjoyed this course.

The course lives upto the hashtag #AsliEngineering, and not just cracking interviews. The depth and nuances that Arpit covers in each system that we design is worth the time spent on the course. The add-on benefits of a great community and networking is also great.

This course definitely lived up to its name - VERY LEGIT - “#AsliEngineering”. These classes became the highlights of my weekends.

Arpit has designed the course in such a way that you will be able to relate the content of every class to its next one. He wouldn’t straight up give you a solution with random jargon nor would he recommend using one technology over other without proper reasoning. He rather conducts brainstorming sessions where he nudges us to come up with solution. While doing so, he discusses the tradeoffs, he encourages to see the patterns and reuse the solutions discussed/built in the previous classes.

I highly recommend taking this course. It is a course worth investing your money and time on.

This course challenged my fundamental understanding of systems designing & made me appreciate the beauty, intricacy & logic of software at scale. Arpit is a natural teacher & passionate tech evangelist who will start from the ground-up & then refine your concepts with this hands-on-engineering journey.

To start with, this has been one of my best decisions in life to join Arpit’s cohort. Despite there being “too many sources for system design on the Internet” as people say, I haven’t seen a single course or educator talk about an in-depth dissection of a given system and questioning different alternatives for even small micro-decisions, which are very critical and which Arpit covers in great depth for all the problem statements.

The aim throughout the course is to build intuition and a strong foundation. With a cohort-based model, learning increases multiple folds and it feels like a day-to-day technical discussion that you have with senior folks at work, which makes it the most fun part of all.

There are people with varied experiences here, and you get to learn from their experiences as well as get to connect with them, which is an added advantage. The “cost - driven development” mantra, as Arpit says in every design discussion, is an aspect that I have seen no one touch upon, and it is something that leads to very exciting discussions and approaches.

Arpit’s energy and passion for computer science are infectious and something that rubs off on everyone in the cohort, leading to great brainstorming sessions. I would personally recommend this course to anyone who loves backend engineering and computer science in general to be a part of great technical discussions, not just for the sake of interview preparation, but to learn and have fun while building systems!

At least I did for the same reason :)

Arpit has the knack of breaking down a very complex problem into simpler and smaller understandable components. The problem statement followed by the solution is communicated very clearly and in a structured way. The live sessions unfold so beautifully that you don’t realize that you have been listening to someone for 2.5 hours straight.

One of the nicest attributes about Arpit other than being brilliant at his field is that he shares the knowledge without being condescending. My approach to work has certainly changed after the cohort. Thanks for the knowledge, keep up the great work.

Honestly, this is one of the best courses I have been in till date. I thought I would probably know like 60% of the topics, but as and when we are completing this, I can be sure that I knew no more than 30% of topics discussed.

Some topics, systems, designs are so fabulous, using the same things we use everyday, and seeing them work and make our systems fault tolerant were mind blowing.

The delivery of the lectures, making it interactive, the efforts in building the notes, discussing all the points and also teach us more than engineering - How to be a “better” engineer and ask the right questions, think on the right lines is what motivated me the most and I got from this cohort.

This I feel would make me go a long way in my personal career space, just because of the “mode” of content delivery. Seeing youtube videos / reading articles or theory doesn’t make sense till the time you actually solve a problem. Even if these were on calls, they looked like actual Product Development calls we have in office where we design something from scratch, thinking about everything.

Thanks for the efforts you put in and helped me and the community. :)
