Hello, World! 👋

Welcome to my portfolio and blog! I’m Shoaib Hasan, a Backend Architect and Distributed Systems Expert passionate about building scalable systems that power millions of users.

Who I Am

I specialize in designing and implementing distributed systems, microservices architectures, and cloud-native solutions. With experience building platforms that handle significant scale, I’ve learned that great backend architecture isn’t just about code—it’s about understanding system behavior, trade-offs, and the art of making complex systems simple.

What I Do

• Backend Architecture: Designing scalable, maintainable systems
• Distributed Systems: Building resilient microservices that handle millions of requests
• Cloud Infrastructure: Leveraging AWS, Docker, and Kubernetes for production systems
• Blockchain Technology: Exploring decentralized systems and smart contracts
• Open Source: Contributing to projects that make developers’ lives easier

My Journey

I’m based in Dhaka, Bangladesh 🇧🇩, and I’ve had the privilege of working on systems that generate $200K+ in platform revenue while maintaining 99.9% uptime for 30K+ users.

One of my proudest achievements was winning 6th place internationally at the International Blockchain Olympiad (IBCOL) 2023 in Amsterdam, Netherlands. This experience deepened my understanding of blockchain technology and its potential to transform industries.

Why I Write

I believe in sharing knowledge and learning from the community. Through this blog, I hope to:

• Document lessons learned from real-world production systems
• Share architectural decisions and the reasoning behind them
• Discuss challenges and how I’ve overcome them
• Connect with fellow engineers who are passionate about building great systems

What’s Next

I’ll be publishing articles regularly on topics ranging from deep technical dives to practical guides. Some upcoming posts I’m planning:

• Building resilient microservices: patterns and practices
• Event-driven architecture: from theory to production
• Kubernetes in production: lessons learned
• Blockchain scalability: exploring Layer 2 solutions
• System design case studies: real-world architectures
