I'm Arslan Ahmad, co-founder of DesignGurus.io and the creator of the 'Grokking' series of courses on system design and coding interviews. Over the years, I’ve worked at companies such as Meta, Microsoft, and Hulu, where I built and scaled distributed systems, developed data storage infrastructure, and helped ship real-world applications used by millions.

Teaching and mentoring have always been a passion of mine. Through DesignGurus, I’ve helped thousands of engineers level up their skills and secure roles at top tech companies. I focus on sharing real insights from my own experience, not just textbook knowledge.

Whether you're preparing for a system design interview or trying to master problem-solving techniques, I’m here to help you break things down, understand them clearly, and move forward with confidence.

I’m a SWE @Snap and ex-Amazon SDE, where I spent over 3 years as a professional interviewer. I’ve run 200+ mock interviews and helped engineers break into top-tier companies with confidence.

I don’t just run through questions—I coach you like a real interview loop would.

Whether you're struggling with DSA, system design, or behavioral rounds, I’ll help you build a sharp strategy, fix blind spots, and communicate like a top-tier candidate.

Let’s get you interview-ready—the smart way.

I am co-founder at DesignGurus.io. Over the years, I’ve worked as a Senior Development Lead at Microsoft on Azure Storage and as a Software Engineer Lead at Meta, building large-scale systems and tackling tough engineering problems.

I’ve always enjoyed breaking down complex ideas — whether it’s system design, algorithms, or scalable architecture — and making them easier to understand. That’s what led me to mentoring.

At DesignGurus, I focus on helping software engineers prepare for interviews and grow in their careers. My approach is practical and based on what actually works in the industry — not just theory. If you're aiming for a top tech role or just want to level up your skills, I’m here to help.
