Hey, I'm Sameer 👋 — a Software Architect with 20+ years of hands-on experience designing and transforming large-scale, mission-critical systems for Fortune 100 clients across Europe, North America, the Middle East, and ANZ. System Design and Architecture is not just my profession — it's my obsession. From Microservices and Event-Driven Architecture to Cloud Native, Domain-Driven Design, and Generative AI — I've architected complex, globally distributed systems across industries like BFSI, Telecom, Public Sector, Healthcare, and Retail. I've also authored 10+ books on System Design, IT Architecture, and Microservices — used in university programs worldwide — so breaking down complex concepts in ways that actually stick is kind of my thing. I'm a Global Top 20 Thought Leader (Thinkers360), IBM Champion (Top 1%), Oracle Certified Master Java EA, and TOGAF certified — but what drives me more than any title is seeing someone finally get system design and use it to unlock the career they've been working towards. If you're an aspiring architect trying to crack system design interviews, understand real-world architecture patterns, or build the mental models that senior architects actually use — this is exactly the space for you. No textbook theory. No gatekeeping. Just real system design, the way it works in the wild. 🚀
