Learn System Design With This Newsletter 🔥

tl;dr: I’m adding a paid subscription plan.

August 2023 - Ko Samui, Thailand.

I went there on a family vacation and was lucky to stay at a beautiful place.

But I couldn’t write long articles on my website as the internet and power there weren’t reliable.

So I started this newsletter.

Now it has grown to 167,000+ subscribers, and I want to make it more valuable for you.

But I won’t be able to grow and improve this newsletter without your support. So I’m adding paid subscriptions on 1 August 2025 (tomorrow).

I’ll send occasional deep dives to paid subscribers besides weekly newsletters. Here’s a sample deep dive.

(I shall add more benefits for paid subscribers later based on requests.)

Pledge your support

Do you find it difficult to stay updated because of limited time? Or you don't know which topics are important to learn? Then you should consider subscribing to this newsletter.

I write this newsletter to help you become good at system design by spending less than an hour each month.

If your employer has a learning budget, you can ask them to pay for this newsletter. Just use one of these templates for it.

You can also get a group subscription at a reduced price. (It comes with a single invoice.)

And if you live in a country with low purchasing power, or you're a student, simply reply to this email to get a discount. Please don't forget to mention the country name.

Pledge your support

This newsletter subscription will pay for itself.

Here are 5 ways it has helped its subscribers:

  1. Learn from case studies

Subscribers get simplified breakdowns of real-world architectures and fundamentals. So they spend less time doing research; instead apply those concepts at work.

  1. Accelerate your career

Each newsletter is to be read in a few minutes and remembered for years. Subscribers have impressed their team members, earned promotions, and passed interviews.

  1. Deliver impact at work

Subscribers have reduced infrastructure costs, improved performance, and contributed more to architecture decisions. Thus getting more recognition from their managers.

  1. Communicate like a leader

Subscribers have learnt to explain complex architectures to team members and even product managers. Besides they learned how to run better design reviews and mentor others.

  1. Mentorship in your inbox

Subscribers say this newsletter helped them better understand technical discussions and design tradeoffs. Thus enabling them to make better design decisions and avoid burnout at work. Also they feel interview ready when it’s time for a job change.

This newsletter isn't just about learning system design.

It's about growing your career and income.

Pledge your support

If you don't see the results within 9 months of paid subscription, let me know. I'll then extend your subscription until you see results without extra cost.

Here are 100+ happy subscribers who think you'll love it, though:
