👋 About These Guides

I've worked at FAANG companies and fast-moving startups.

Over the years I sat through hundreds of system design discussions, failed interviews, passed interviews, and watched others do the same. I took notes on everything — what worked, what didn't, and what nobody on YouTube actually explains clearly.

I compiled all of it into two focused PDFs.

━━━━━━━━━━━━━━━━━━━━━━

📐 SYSTEM DESIGN PDF

Not another 10-hour course. This guide cuts straight to the patterns and trade-offs that senior engineers think about every day — and that interviewers are actually testing for.

What's inside:

✅ Core system design principles (simplified)

✅ Architectural trade-offs explained clearly

✅ Patterns from real production systems

✅ How to think and communicate like a senior engineer

Perfect for: devs prepping for system design interviews, juniors levelling up, or anyone tired of vague explanations.

━━━━━━━━━━━━━━━━━━━━━━

💻 DSA MASTERY PDF (C++)

Pattern-wise. Clean solutions. Real problems from Google, Amazon, Microsoft, Meta, and more.

Covers: Arrays → Two Pointers → Hashing → Sliding Window → Kadane's → Recursion → Backtracking → Trees → Dynamic Programming → Stack → Queue → Linked List → Binary Search

Built from real interview experience — on both sides of the table.

The gap between junior and senior dev isn't years of experience.

It's how you think about problems.

Juniors ask: "how do I build this?"
Seniors ask: "should we build this, and if so — how do we make it scale?"

That shift doesn't happen automatically. It takes deliberate learning — and most people don't know what to study or in what order.

That's why I created a system design PDF that gives you a clear foundation — the concepts that actually come up in senior roles and system design interviews.

And if you want a more personalised path — whether it's a learning roadmap, career direction, or just a conversation with someone who's been through it — I also do 1 on 1 coaching sessions.

A few years ago, I was confused about where my career was going.

Good job on paper. But no direction. No plan. No one to talk to who actually got it.

I figured it out eventually — but it took way longer than it should have.

That's why I'm now opening up 1:1 sessions for anyone who's at a crossroads:

↳ Should you switch companies or go deeper where you are?

↳ How do you transition into a new tech stack or role?

↳ What does your next 2 years actually look like?

Whether it's career advice, a tech learning plan, or just making sense of the bigger picture — I'll help you think it through.

Limited spots. Honest conversations. Practical outcomes.

The #1 mistake junior devs make in system design interviews

Most junior engineers jump straight into drawing boxes and arrows. They start talking about microservices, Kafka, Redis — throwing out buzzwords like they're solving for Netflix at 200M users.


The interviewer isn't impressed. They're confused.


Here's what actually works:


Start with requirements. Every single time. Ask clarifying questions for 3-5 minutes before you draw anything:

  • What are the core features?

  • How many users? What's the read/write ratio?

  • What matters more — consistency or availability?


This does two things:

  1. Shows the interviewer you think before you build (senior trait)

  2. Gives you constraints that make the design 10x easier


A junior dev designs for "scale." A senior dev designs for specific constraints.


I broke down the exact framework I used to pass system design rounds at top tech companies into a guide — covers 15+ real questions with detailed solutions, from URL shorteners to distributed message queues.


If you're a junior dev trying to break into a senior role, this is the playbook.
