About

Hi, I'm Hồ Bảo Lân — a software engineer who loves building scalable backend systems.

I write about system design, ASP.NET, Spring Boot, and software engineering in general. My goal is to share practical knowledge that helps developers build better systems.

This blog is where I break down complex topics into digestible articles — from distributed systems and microservices to API design patterns and database optimization.

What I write about

System Design — Scalability, distributed systems, load balancing, caching strategies
ASP.NET / .NET — Web APIs, Entity Framework, authentication, middleware patterns
Spring Boot / Java — REST APIs, Spring Security, JPA, reactive programming
Architecture — Microservices, event-driven design, CQRS, DDD
