The Course

This is a beginner-friendly self-paced course on system design aimed at providing an exclusive and crisp introduction to building systems. The program will cover most of the topics under System Design and Software Architecture from scratch assuming no prior knowledge.

Program pre-requisites

The course operates at a beginner-level and hence does not assume any prior knowledge of system design. We would start with absolute basics and then scale up to build real-world systems in a very structured way. By the way, there is just one pre-requisite to this course

  • a Google account because I only support Sign-in with Google :)

Why should you join?

The primary objective of this program is to make you comfortable at building systems that are scalable, fault-tolerant, and reliable. But here is what you could reap out of it.

Design systems like a pro

The course will make you comfortable at designing any system, no matter how stringent the requirements are.

Know the unknowns

Learn some of the most interesting concepts, super-clever algorithms, and sophisticated architectures. You are bound to have mind-blown moments.

Crack the interview

Be it FAANG or your dream startup, you would be at ease while designing systems in the interview round.

Upskill and level-up

Learn the designing paradigms and upskill yourself to accelerate your career growth and stand out.

The world is learning

People from all over the world have mastered System Design through my other System Design course meant for experienced engineers.

Arpit Bhayani

Hi, I'm Arpit Bhayani 👋

In my last ~9 years of experience, I have worked at D. E. Shaw, Practo, Amazon, and Unacademy; and have built systems, services, and platforms that scaled to billions.

Post my masters in CSE from IIIT Hyderabad I joined D. E. Shaw for a short stint of 2 months, before moving to Practo and working there as a Platform Engineer, building and owning close to 8 different microservices. Post Practo I worked at Amazon on their primary mission-critical E-Commerce Database and built Data Pipelines that cold tiered the stale data.

After quitting Amazon in 2018, I joined Unacademy as their first Technical Architect and there I designed, built, managed, and scaled services like Search, Notification, Logging, Deployment Engine, and many more. I have now transitioned into the role of a Sr. Engineering Manager, leading the Site Reliability and Data Engineering verticals.

In January 2020, I started my newsletter where I write and share an essay about programming languages internals, deep dives on some super-clever algorithms, and few tips on building scalable distributed systems. The newsletter currently has 38000+ readers.

Recently, I have started building Revine - a programming langauge for kids helping them develop logic through animations and spark their creativity through artwork.

What people say about my courses?

Some testimonials from the people who recently took my courses.

Nityananda Gohain

One thing I can guarantee that after this course you can read any kind of system design book/blog with confidence and you will be able to relate to Arpits classes in someway or the other, also Arpit designed the course in such a way that you will be able to relate to previous classes and bring out patters in solving problems. My best investment ever :)

Tejas Agrawal

Had a super fun in learning how to learn and think system design. I am already using Arpit’s teachings at my work, and I don’t think anything more needs to be said.

Rohan Chougule

It’s easy to throw jargons and assume that a system can be built. But then keeping things simple and starting from the basics, the approach to be taken, taking baby steps, and then heading towards a direction is indeed best taught by Arpit. Plus, his enthusiasm!

Sai Subramanyam Chittilla

Arpit is a passionate individual who teaches one of best system design course, his explanation comes from real implementation and exposure to the problem. He makes sure that individuals develop critical thinking when approaching system design.

I would highly recommend his course for any one who tries to build systems to scale.

Frequently asked questions

You can always drop me an email at arpit.masterclass@gmail.com for other questions.

Is this a cohort based course?

No. This is a recorded self-paced course with bi-weekly doubt solving sessions with me.

How is this course different than your system design masterclass?

Masterclass and Beginner course are mutually exclusive. Beginner course is for absolute beginners and starts things from scratch. Masterclass assumes you have some understanding of systems and we take it forward from there. There will be very minimal overlaps in the topics I cover in the two courses. In general, if you have some understanding of systems and have watched existing system design videos, go for the masterclass. If you want to start from absolute scratch then opt for beginner one.

Is this course right for me?

This course is for any engineer who wants to get started with System Design. If you are a college student or a working professional wanting to start with System Design, this course is for you.

Is there a limit to number of doubt solving sessions I can attend?

No. But the discussion will be strictly related to topics discussed and covered in the course.

Will you be giving teaching for the entire duration?

Yes. I will be teaching the entire course.

Will the course cover LLD?

No. The course is focussed on High Level Design only.

Will we also implement and see the systems in action?

It is not possible to implement every system; it is recommended that you self-implement the system and understand the low-level details. The course will definitely cover systems from every aspect.

Will there be a recording available for future reference?

Yes. You will have lifetime access to the recordings of the course.

Is there a refund policy?

3 day refund window from the day you purchased the course (11:59:59 pm on the rd day from the date of purchase).

Can I share my learnings, resources on social media?

No. I hold complete right to cut-off the access to any course material if I find you sharing course material, learning, videos, and notes on social platforms or the internet.

Will you be the only one teaching this course?

The entire course will be conducted by me, Arpit Bhayani, no external TAs, mentors, etc. You will get to learn everything from the horse's mouth.

What are the programming pre-requisites?

There are no programming pre-requisites, but having a basic idea is always better.

How is this course different from your other system design course?

My System Design Masterclass is an intermediate-level course and hence assumes you know basic system design. This course assumes nothing and will ramp you up on everything you should know about it.

If I have already watched System Design videos on YouTube, is this course still helpful?

Yes. The kind of depth which is touched in this System Design is unmatched. Even if you have watched all the System Design videos out there, you will still have moments that will blow your mind.

Will I be getting an invoice of Payment?

Yes. An invoice will be issued to you with all the legal and necessary details. This means your employer can choose to process this invoice and provide reimbursement.

Will you issue a course completion certificate?

I do not generate the certificate for every candidate, but if you need it, just drop me a message, and I will issue one right away.

Can I use my Credit Card or avail EMI to make the payment?

Yes, we support Credit Card, Debit Card, UPI, and Credit Card based EMIs having a duration of 3 months, 6 months, 12 months, and 24 months as offered by Razorpay.

When are you launching the course?

The course will be launched on 8th April, 2023 and you will be notified about it over email.

Can I share the account with multiple people?

I track the browsers and devices from which the course is being accessed and if I fnd anything suspicious, I hold the complete right to revoke the access of the course and not offer any refund.
